ON THE COVER:It takes a special touch — and a strong leader — to keep a 120-year-old water plant ticking. That’s what Scott Bailey has done for more than 25 years in Monticello, Ill. (Photography by Bradley Leeb)


Try to remember a time when it was harder to locate funds to improve water system facilities (or for that matter any public infrastructure).

Equipment and buildings are aging. Things are falling into dis-repair. Downtime is a worry. Updates to newer and more efficient

technology would improve service right away and save money in the long run, but that would require an up-front investment — and where will the money come from? Especially when the decision-makers and customers have little appetite for a rate increase in a still-troubled economy.

The answer may be simpler than it seems, and it doesn’t involve some new-fangled, exotic financial instrument. Sometimes it’s easy to overlook a proven solution that has been around for years. In fact, the one I’m about to describe is so well proven and so low risk that I’m amazed more public- and private-sector entities don’t use it.

No leap of faith

It’s called performance contracting, or in the parlance of the federal government, which uses it extensively, energy-saving performance con-tracts (ESPCs). Across the nation, this tool has been used to improve effi-ciency at military bases, upgrade schools and city halls, renovate hospitals and, yes, reinvigorate water utility operations.

Water utilities have used it to upgrade aging pumps, replace water meters, install automated meter reading (AMR) and advanced metering

infrastructure (AMI) systems, install leak detection systems and more — and in the bargain improve energy efficiency in the administration build-ing, with high-efficiency lighting, better comfort controls, new windows and thicker insulation.

Best of all, performance contracting lets a utility take on a big bundle of projects all at once (instead of nibbling away at things year by year), and do it without investing any of its own capital. So what’s the catch? Try as I might, I can’t find one.

Simple concept

The concept behind performance contracting is simple. Efficiency improvements pay for themselves over time. So why not go ahead and make the improvements and let the savings themselves make the annual payments?

In a typical performance contract, an energy service company provides

the capital to finance a package of improve-ments that have been analyzed up front and projected — based on solid information — to deliver a specific level of savings. Those savings are then guaranteed by contract over a defined term, typically 15 to 20 years.

Ideally, the annual savings exceed the amount of the annual payment on the improvements, so the utility sees somewhat lower costs right off the bat. At the end of the contract term, the utility reaps all the annual savings.

During the contract term, the actual savings are tracked. If the amount of savings in a given year exceeds the guaranteed amount, the utility pockets the excess. If the savings fall short of the guarantee, the energy service company has to write the utility a check to make up the difference.

Time to take a look?

It’s hard to imagine any other way to make wholesale improvements with the bare minimum of risk (next to none) and without laying money on the table up front. The old adage — if it sounds too good to be true, then it is — may not apply in this case.

Any number of highly qualified and reputable energy service compa-nies can complete performance contracts. In today’s fiscal times, this cer-

tainly looks like a financial tool worth exploring carefully.

And speaking of innovative approaches, this issue of Water System Operator profiles a water plant in Tampa, Fla., that was constructed under a design-build-operate (DBO) contract. DBO is a departure from the traditional bid-to-spec approach

that offers advantages for many projects.

What do you think?To my less-than-expert eye, it seems the best feature of DBO is that it

forces the chosen contractor to think not just about holding down the cost of construction, but about holding down the total lifetime cost of owner-ship. That means a facility built under DBO is likely to include not the lowest-priced equipment and components but those that will be the most reliable and the least costly to operate in the long run. This, too, looks like an avenue worth investigating in times of fiscal stress.

Do you have experience with performance contracting or DBO? If you have tried them, what was the outcome? If you haven’t, why not? We would like your thoughts. Send me a note at [email protected]. I promise to respond, and we’ll include the comments in a future issue. wso

W ater System Operator aims to bring stories that help you and your plant perform better. Now we do more of the same on the WSO website. There you’ll find stories that appear only online — and that are current, because they’re not subject

to the lead times involved in the print magazine. Here are a few online exclusives recommended by the WSO editorial team:

Xylem expands range of Medium-Pressure UV Water treatment solutions

Xylem has expanded its range of medium-pressure UV water treat-ment solutions with the launch of two additions to the WEDECO Quadron series, suitable for drinking water disinfection and also for fish farming, swimming pool and wastewater reuse. The Quadron series is validated according to the U.S. EPA UV Disinfection Guidance Manual. It can be uniquely tailored to meet the requirements of individual water or wastewater treatment facilities.

Louisville Water Kicks off Pumping station restoration and Water Works Museum

A project to restore the interior of a National Historic Landmark in Louisville, Ky., began this year. The Louisville Water Company kicked off a restoration project at its original pumping station. The project will renovate and restore the interior of pumping station No. 1, built between 1858 and 1860 as part of the city’s original Water Works. The site also fea-tures the city’s iconic water tower, also a National Historic Landmark.

Program offers Multi-Faceted Learning With training Laboratory

Mike Smith’s enthusiasm for the Water Quality Management pro-gram at Red Rocks Community College is contagious. And his pride in the curriculum he’s helped build is clearly justified. The college, at the foot of the Rocky Mountains in Lakewood, Colo., has one of the most extensive water quality management programs in the United States with an enclosed mobile laboratory used for coursework and as an emergency response unit in the event of a water-borne disease outbreak. “There’s really no other institution with anywhere near the offerings we have,” says Smith, department chair, program coordinator and lead faculty member.

Virginia Water department earns 2012 excellence in Water treatment Plant Performance Award

The City of Manassas Public Works and Utilities department received the 2012 Excellence in Water Treatment Plant Performance award from the Virginia Department of Health Office of Drinking Water. The awards were recently presented in Roanoke, Va.

“The City of Manassas is dedicated to maintain quality water for our citizens,” said Mike Moon, director of the city public works and utilities department. “We’re honored to be recognized for our water treatment performance.” Three levels of performance are honored: gold, silver and bronze. Manassas earned the silver designation. wso

IncentIves to conserve I read your article about water conservation in the June 2013 edition

of Water System Operator [On Tap: The Conservation Paradox]. I found it quite interesting in light of the way municipalities have handled water rates over the past years.

I work for the Detroit Water and Sewerage Department and have seen decline in water demand, and yet the costs have gone up for the custom-ers. Although there is no immediate remedy to this, I do believe there are ways to entice the customers around the country to help in water conservation.

With the ever-increasing cost of chemicals used in water treatment plants, and the increasing cost of electricity and staffing, the term “water conservation” is the only viable and necessary practice. Lowering water rates, as we all know, just will not happen. People will continue to reduce their water consumption, and the rates will continue to rise due to lower product demand, as we have seen in the past.

Here is my idea: Municipalities have many residential/family perks — such as swimming pools, indoor hockey rinks, recreational centers, parks, and sometimes the occasional trip to an amusement park or casino. All of these the residents must pay for using. My family does not partake of these because we can get them all cheaper elsewhere.

But if cities would offer freebies to families that met a water conserva-tion budget, I think this would help in water conservation and might also help bring future business and revenues to municipalities by showing what can be offered. Free memberships or a free day at the pool — there are many possibilities. Cities won’t go broke offering such things, and they just might help attract new residents.

I understand that cities are a big business, but in order to make resi-dents and customers happy, incentives to reward conservation sound like a good business practice. It can show that a city cares in many ways.

It takes a special touch — and a strong leader — to keep a 120-year-old water plant ticking. That’s what Scott Bailey has been bringing for more than 25 years.

Now plant supervisor for the Monticello (Ill.) Water Plant, Bailey started as a laborer with the city Public Works Department in 1987. He

has forged a career built on learning all he can about the water business, developing his expertise and motivating the operators who work for him.

Indeed, Bailey has proved himself a savvy manager and an innovator at the 1 mgd facility, with 2,460 service connections in this city of 5,300, an hour east of Springfield between Champaign and Decatur. After learn-ing that the plant supervisor would retire in five years, Bailey kept his eyes on the prize. He took courses at two community colleges, eventually earning an associate degree and a certificate in management. He also attended AWWA seminars.

In three years, he earned his Class A Surface Water license, and he became water supervisor in 1996. “When I first started here, I felt like everybody else: you just turn on your tap and the water is there,” Bailey says with a smile. “The fact is, you learn something new every day, and I love that part of the job.”

Seeking advancement After high school in Monticello, Bailey went to Lincoln Land Com-

munity College in Springfield for the water classes he needed to get his license. Then he attended Parkland Community College in Champaign.

Bailey decided to shoot for a degree, which he felt would make him

more valuable. “Originally, my associate degree was to have been in con-struction technology, but I needed a few classes during the day, which I couldn’t take because I was working, so I ended up changing my major and getting a degree in general studies,” he says. “I also took a set of manage-

ment courses at Parkland and earned a certificate. That has been a big help in my supervisory duties.”

Bailey’s determination paid off at the water plant, built in 1892. He shows pictures from the early 1900s and points out that until a major renovation in 1935, the facility’s water softeners were steam-powered. The oldest well, still in use, was built in 1915. Other reno-

vations took place in 1958 and 1976. Nonetheless, “Our water meets all federal and state standards; we haven’t had a violation in years and years.”

It takes a special touch — and a strong leader — to keep a 120-year-old water plant ticking. That’s what Scott Bailey has been bringing for more than 25 years.

Now plant supervisor for the Monticello (Ill.) Water Plant, Bailey started as a laborer with the city Public Works Department in 1987. He

has forged a career built on learning all he can about the water business, developing his expertise and motivating the operators who work for him.

Indeed, Bailey has proved himself a savvy manager and an innovator at the 1 mgd facility, with 2,460 service connections in this city of 5,300, an hour east of Springfield between Champaign and Decatur.

(Siemens) for iron and arsenic removal and four ion-exchange water soft-eners (Siemens). The plant averages 500,000 to 600,000 gpd. Treated water goes into a 750,000-gallon clearwell. The city also has two water towers that hold a combined 650,000 gallons.

“A typical day at the plant starts with taking readings,” Bailey says. “We have a SCADA system where we get readings on our pumps and meters. We check the plant inside and out, then come back and do our testing at the lab. We also do maintenance inside the plant and keep the infrastructure in shape.”

His biggest challenge came in 2006 when the U.S. EPA reduced the arsenic limit in drinking water from 50 parts per billion to 10. From the time he heard talk about the new regulations, he began doing pilot stud-ies, experimenting with treatments and chemical combinations that finally yielded the 10 ppb level. But Bailey wanted to do even better.

“We used a lot of chemicals, and I was able to eliminate some of them through trial and error,” he says. “We had a chemical engineer who wanted to treat the water with chemicals, so we started out using copper sulfate, hydrogen peroxide, ferrous chloride, chlorine bleach and a SUPERFLOC A-1894RS polymer (Kemira).

“We reached 10 ppb, so I started changing the formula and eliminating one chemical at a time, doing some testing and sending samples into the lab. Just by accident we upped the polymer until we finally got the arse-nic level to 6 ppb. What really worked best was using bleach at the well and then adding the polymer right before the water went to the filters.”

Beyond the positive health impact, there was an economic benefit to the arsenic removal, according to Floyd Allsop, city manager and Bailey’s boss for 18 years. Allsop feared that the new regulations and the accom-panying increase in chemicals would force the city to raise water rates in a tough economic climate.

“Scott worked with engineers and others, experimented, tested and came up with a relatively low-cost way to reduce the amount of chemicals we use and still cut arsenic levels to below EPA standards,” Allsop says. “As a result, we’ve been able to hold rates steady. In fact, we haven’t had a rate increase in more than five years, and that’s a real credit to Scott and his team.”

earning honors

Such devotion drew notice in 2012, when Bailey was named Operator of the Year by the Illinois Potable Water Supply Operators Association (IPWSOA). His quarter-century of service includes being a member of the Iowa AWWA section and serving on its Small System Committee, being a member of the Illinois Rural Water Association, and serving on the City of Monticello’s Safety Committee.

Bailey joined three finalists on stage at last September’s IPWSOA annual conference in Springfield. “Then I looked around, saw I was the only one left, and thought ‘Oh, that’s me,’” he says. He earned the award in the Groundwater Division after a rigorous selection process that included extensive review of plant performance, interviews and a plant tour by IPWSOA committee members. In typical fashion, Bailey credited just about everybody but himself: his two Class A operators, Tom Bates and Matt Utley; and the city Public Works employees.

waTer PlanT SuPervISor 101What does it take to be a successful water plant supervisor? scott

bailey says it starts with listening and responding. “You have to be

sensitive to what people in the community want. clean water, sure, but

they want to keep their rates low. so you have to prioritize maintenance

projects and stick to your budget. that means sometimes you’ll only

replace one or two hydrants a year or two or three blocks of water main.”

another key to success is leading by example. “When we have a

water leak, my guys aren’t the only ones in the hole,” he says. “i’ll get in

with them. We take turns on fixing water main breaks. the guys are good,

and you have to show that you support them.”

responsiveness is another requirement. says bailey, “Whenever we

have a leak, we try to get there as quickly as possible. i’ve had people

complain about their dirty water and give us holy heck on the phone,

but then they praised us because we responded so fast. You have to

take care of things right away.”

scott bailey, with water operators tom bates, left, and Matt utley.

scott bailey believes in leading by example.

Allsop observes, “With Scott as water supervisor, I don’t have to worry about ensuring that our water meets state and federal standards. He takes quality water personally, so I know that whether he’s at the plant or on vaca-tion, he’s monitoring it and keeping in close contact with the other oper-ators. It’s a good feeling to be able to trust someone to do the right thing.”

The Water Department has received a Fluoride Award from the state Department of Public Health for seven consecutive years for maintaining the proper fl uoride levels all 12 months. Again, Allsop credits Bailey and his team.

“This is an older facility, which Scott has been able to maintain and upgrade when the need arises,” he says. “Scott and I have a budget for maintaining the plant and the infrastructure. This includes replacing undersized or old water mains or changing out three or four fi re hydrants every year. That can be expensive, since we often have to replace fi ttings and valves. We’re able to do this cost-effectively because of Scott’s knowl-edge and experience. He has lots of good ideas, and he isn’t afraid to try new and innovative approaches and work with others.”

Those who work for Bailey share Allsop’s assessment. Bates, a 17-year veteran, says, “If Scott were a coach, he’d be a players’ coach. He’s been there and done that, so you have confi dence he knows what he’s talking about. Scott will always say, ‘Can you do this?’ rather than ‘Go do it.’ That’s his style. He’d never ask us to do anything he wouldn’t do. When we have a leak or main break, he’ll go down in the hole and work with us to fi x it. He’s 100 percent hands-on, which is great in a supervisor.”

Utley, who has been at the Monticello plant for fi ve years, considers Bailey “a mentor and father fi gure. When I started here, I had my Class D [distribution] license, and Scott encouraged me to better myself and

get my Class A license. I’ve really enjoyed working for him. He knows so much about water and the plant and what it takes to be a good operator.”

Toni Sommers, a water department billing clerk, adds her two cents: “Scott’s a great guy to know and work with. He’s one of a kind — very cooperative and always willing to help. He gives tours for high school kids, and they really enjoy hearing him talk about the water plant.”

Job that never ends

While grateful for the praise, Bailey remains focused on his work, which includes a program to replace three or four blocks of water main per year. Last year, he and the Public Works staff put in a mile of new water main. He also considers which hydrants to replace, taking that seri-ously because hydrant prices have gone from $900 to more than $2,000 in the last several years.

Bailey also serves as water operator at three small water treatment plants about 10 miles from Monticello: the Village of Cisco (serving 300), the Village of Deland (300), and White Heath Water Works (600) resi-dents. He does the work on Satur-days, making sure the plants are running the way they should.

Bailey insists it’s all part of the job. “People often take water for granted,” he says. “It’s nice when we go on a job and someone says, ‘That’s a lot of work; thanks for get-ting our water back.’ I’m proud to be part of the plant’s success.” wso

Perfectionists. That’s the conclusion you draw after a conversation with the treatment crew at the 2 mgd Bridge Creek Water Treat-ment Plant in Homer, Alaska. Superintendent Todd Cook and his staff strive to improve constantly as they deliver drinking water to 1,500 customers in this community on the Kenai Penin-

sula, 200 miles southwest of Anchorage.The plant includes the largest ultrafiltration membrane installation

for drinking water in the state, but the Homer operators don’t let such advanced technology keep them from tweaking plant processes and adjusting chemistry. They’re on the alert against organics, iron and man-ganese, disinfection byproducts and more, and they have even made adjustments to the membranes and the control systems to give them bet-ter results. “We don’t get bored around here,” Cook says.

Step up to membranes

For many years, the Bridge Creek plant used pressure sand filters, but frequently had to deal with filter blinding. Filter backwashing required a high volume of water, reducing the amount of finished water for custom-ers to only 40 to 60 percent.

The ZeeWeed ultrafiltration units (GE Water & Process Technologies) are the highlight of a major plant upgrade completed in 2009. Raw water comes from the 35-acre Bridge Creek Reservoir, a few hundred yards from the plant. Byron Jackson multi-stage turbine pumps (Flowserve Corp.) bring the water uphill to the plant, where it passes through strainers (S.P. Kinney Engineers) and then is mixed with recycled water decanted from the filter backwash water ponds.

Alum is injected in a rapid-mix tank to promote development of pin-floc in the flocculation basin, which is equipped with three impellers. “We don’t want a bigger floc, because that could blind the membranes,” explains Jerry Lawver, lead operator.

After the floc basin, the water is gravity-fed to the membranes. The membrane train consists of five cassettes, each with 48 modules. The cas-settes can hold 64 modules, a feature that will make it easy to expand. Each module contains thousands of vertically strung membrane fibers, with millions of microscopic pores in each strand. Water is filtered by

A new ultrafiltration system resolved many issues for the team in Homer, Alaska, but that doesn’t keep them from working diligently to continue getting better

applying a slight vacuum to the end of each fiber, drawing the water through the pores and into the fibers themselves.

The filtered water is dosed with orthophosphate for corrosion control and adjusted for pH with caustic soda. Chlorine for disinfection is gener-ated onsite in a Miox system, which creates sodium hypochlorite and hydrogen gas through electrolysis of salt.

While on-site generation is becoming more common due to the risks of transporting chlorine over the road, Homer uses the technique mainly because shipping chlorine to the plant would be difficult. “There are few roads, or no roads, up here,” Cook says. “Liquid chlorine would have to come by boat and would be classified as a hazardous material.”

The filtered, chlorinated water flows to a 1-million-gallon clearwell, then downhill to the city distribution system, which consists of just over 43 miles of pipe and 22 pressure-reducing stations. A small portion of the finished water is provided to private haulers who deliver it to customers in two neighboring communities.

Besides Lawver, Cook’s staff consists of Joe Young and Dave Welty, operators, and Paul McBride and Bob Kosiorek, maintenance techni-cians. They follow a standard membrane cleaning protocol. The filter modules are regularly back-pulsed with an air scour feature and back-washed by reversing the flow. In a maintenance clean, the membranes soak for 15 minutes in a solution of chlorine or citric acid. A full recovery clean involves soaking in a chlorine solution for six hours.

Filter backwash water passes to two backwash water ponds in series. As solids settle, clear water decants from the first pond to the second. From the second, water is returned to the plant inlet, where it is mixed

with raw water. The water recovery rate is 92 percent, meaning that only 8 percent of the water being processed does not end up going to custom-ers — that’s a huge improvement over the old setup.

Keeping it running

While the upgrade to membranes has resolved the issue of filter blind-ing and low water recovery rates, the Homer team continuously seeks to improve treatment operations and water quality. Iron and manganese can cause problems. Cook and his crew have found that the membranes remove most of the iron, but only about half of the manganese. “We used to get black water complaints, and the clear tubing on our chlorine meters would turn black,” Cook says.

By experimenting with increases in the orthophosphate and caustic soda injection rates, the Homer staff brought the manganese issue under control. “We upped the phosphate addition from 0.2 to 2 ppm and are now back to 1 ppm,” explains Cook.

The relatively low pH of the source water, driven even lower by the alum dosing, can also contrib-ute to lead and copper issues and disinfection byproducts (DPBs), so the Homer staff works carefully

to increase pH and maintain it at 7.5 to 8.0. The operators have taken sev-eral other measures to minimize DPBs. “We have only 1,500 connections, and over 43 miles of water distribution lines,” Cook say. “That’s a lot of standing water in the system.”

Joe young, operator iii, checks the pH, alkalinity, turbidity and chlorine levels of a water sample to verify the accuracy of online instruments.

Filter backwash water passes to two backwash water ponds in series. As solids settle, clear water decants from the first pond to the second. From the second, water is returned to the plant inlet, where it is mixed

with raw water. The water recovery rate is 92 percent, meaning that only 8 percent of the water being processed does not end up going to custom-ers — that’s a huge improvement over the old setup.

Keeping it running

While the upgrade to membranes has resolved the issue of filter blind-ing and low water recovery rates, the Homer team continuously seeks to improve treatment operations and water quality. Iron and manganese can cause problems. Cook and his crew have found that the membranes remove most of the iron, but only about half of the manganese. “We used to get black water complaints, and the clear tubing on our chlorine meters would turn black,” Cook says.

By experimenting with increases in the orthophosphate and caustic soda injection rates, the Homer staff brought the manganese issue under control. “We upped the phosphate addition from 0.2 to 2 ppm and are now back to 1 ppm,” explains Cook.

The relatively low pH of the source water, driven even lower by the alum dosing, can also contrib-ute to lead and copper issues and disinfection byproducts (DPBs), so the Homer staff works carefully

to increase pH and maintain it at 7.5 to 8.0. The operators have taken sev-eral other measures to minimize DPBs. “We have only 1,500 connections, and over 43 miles of water distribution lines,” Cook say. “That’s a lot of standing water in the system.”

“We don’t get bored around here.”

The utility recently added variable-frequency drives on its pumps and motors as a way to keep water moving throughout the system. Before, the pumps ran on a fill-and-draw basis; in winter it took six to eight hours to fill the storage tank, and then the system would shut down for 16 to 18 hours. “With the VFDs, the pumps are running at a slower pace and the water keeps moving in the system,” says Cook. “We’ve seen some reduc-tion in DBPs, and our power consumption is more efficient.”

The staff also pays close attention to organics. Influent TOCs come in at about 4 parts per million and leave the membrane system at 2 ppm or less. The operators rely on UV transmittance testing to track TOCs in the raw and finished water, enabling them to better adjust the plant’s alum addition rates.

“We use hand-held UVT meters from Real Tech so we don’t have to send samples out for analysis,” says Cook. “There’s a direct correlation between TOCs and UV transmittance. The higher the UV transmittance through the water, the better organic kill we’re getting. So if our UV transmittance is in a certain range, we know our TOCs are in a certain range, and can adjust our alum dosage rates accordingly. We don’t want to overfeed or underfeed alum.”

On the other hand, turbidity is not an issue. “Our source water is very low in turbidity,” says Cook. “The turbidity in our finished water is 0.02 NTU, rock solid. The filters pretty much do what the manufacturer says they’ll do. They’re awesome from that standpoint.”

That wasn’t always the case in the old days; Lawver remembers the staff used to “backwash and hope the turbidity would come down, then backwash and hope the turbidity would come down.” When summertime temperatures reach into the 60s and 70s, the reservoir can experience

Final analysis

Nearly five years into the $11 million upgrade, Cook and his staff are pleased with the results but nowhere near ready to slack off on fine-tun-ing. “Our membranes have been pretty bullet proof so far,” Lawver says. “They’re making good water.”

The biggest issue has been with programming, Cook says. One of the original issues was with the chemical pumps used for membrane clean-ing. “We were locked out from adjusting the length of time that they would run,” says Lawver. “Run times were too short, especially with the sodium bisulfite — the chemical used for neutralizing chlorine.”

After a chemical clean, he says, the rinse water would have a chlorine residual as high as 2.0 mg/L. The rinse water is discharged to the back-wash ponds, which concentrate the organics removed by the filters.

“The combination of high organics and chlorine created DBPs in the pond,” Cook says. “Tests of the decant water proved DBPs were being formed on site. The operators contacted GE/Zenon to have their pro-grammers remove the locks so the operators could adjust the chemical pumps as needed. It’s under control now. All the chlorine is neutralized before it is sent to the decant pond, and we have seen the DBPs drop off.”

Cook concludes that with advanced technology and a new SCADA system sometimes the engineers and programmers haven’t seen eye-to-eye. “It took awhile in some cases, but the operators got things worked out,” he says.

That’s typical — Alaskans are known for self-reliance and are not ashamed to brag about it.

A dvanced metering infrastructure (AMI) with fixed network communication has given water utilities an abundance of data — typically hourly information on customers’ water usage. The challenge has been turning that data into information that can

guide performance-enhancing actions.Meeting that challenge is the aim of Advanced Metering Analytics

(AMA) from Badger Meter. The technology combines the company’s ORION SE two-way or GALAXY one-way fixed network AMI solutions, its secure analytics-based ReadCenter software, and its family of meters and encoders. Essentially, the system takes in the hourly AMI data, iden-tifies conditions that require attention, and alerts appropriate personnel to take action — all automatically.

Morrice Blackwell, marketing manager for software solutions with Badger Meter, talked about the technology and its applications in an interview with Water System Operator.

wso: What is the market need this offering is designed to address?Blackwell: It’s part of the evolution of automated meter reading

(AMR), which is a very efficient way to get meter information. AMR has been around since the 1980s. The first fixed AMI metering networks for water arrived in 1996 and supplied daily information.

Most manufacturers now have gone to hourly information, but until now all that has done is give utilities loads of data without giving them a reason to have it.

We saw that having hourly interval data in a water system could be very powerful if it were analyzed and presented in a meaningful way. So

we worked with our customers to understand certain conditions they were concerned about within their water systems. And we developed ana-lytics that allow them to take the hourly information and get feedback on those conditions.

wso: What would be an example of a condition this system would flag?Blackwell: Let’s consider under-usage. In any water utility you have

the 80-20 rule: About 80 percent of users are residential, and about 20 percent are commercial or industrial users. In many small communities, five or six large users may make up a very large share of the revenue. If

those meters were to malfunction or slow down mechanically, the utility would lose significant revenue.

One of the analytics we run for customers is for average consumption. We allow them to set up the analytics to alert them when a large custom-er’s metered usage falls a certain percentage below that customer’s aver-age consumption.

wso: In simple terms, how does the analytics process work?Blackwell: First we define the system exceptions the customer cares

about. Next we define the accounts to monitor for those exceptions — say, commercial meters over 2 inches. We then define who at the utility should be alerted when that exception occurs, and how they should be alerted — such as by email or SMS text. We also define how often they should be alerted — the first time the exception happens? Every time it happens? And finally, we define what action they want the person to take upon receiving the alert.

wso: So, how might this process play out if monitoring for

under-consumption?Blackwell: Suppose we set the analytics to flag consumption down by

25 percent from the average on commercial meters 2 inches or larger. When this happens for a given customer, the system would send the meter supervisor or other appropriate party an email saying the account has shown consumption under normal usage, and the action to take is to set up a work order for investigation.

wso: What other conditions would a utility want to monitor?

Blackwell: They would definitely want to know about leaks, tampers and reverse flows. Let’s consider leaks. If a con-sumer has a leak in the home, the endpoint will notify the

utility that the customer is in a continuous usage state. The system will then send an email telling a customer service representative to call the customer.

Another useful alert is for inactive accounts. This is helpful in states like Florida, where for the summer months some residents live elsewhere. Those people like someone to monitor their homes to make sure they don’t get a pipe burst or some leak that goes on while they’re away. The utility can issue a consumption alert, so that if an account in an inactive state uses more than some small amount per day, someone is sent out to investigate that.

“our trainers work with utilities to explain how the analytics work and help them set up the alerts they care about. A utility has to be smart about deploying the analytics.”

MoRRIce BlAckwell

wso: How would notifications work for tampers or reverse flows?Blackwell: If a wire is cut, the endpoint knows there has been a short

in the line, and then broadcasts to the utility that it is in a tamper condi-tion. It could be that someone is trying to steal water, or it could be that the wire was damaged by accident.

Reverse flow could occur because of poor piping condition. Or you could have an industrial user operating at a pressure that overcomes the normal water pressure in the system. The AMA system would let the util-ity know, and someone would be alerted to take action right away.

wso: Are there any alerts to possibly notify someone about a mal-

function in the metering equipment itself? Blackwell: Yes. Endpoints that have been out in the field for a long

time will send an alert if they go into a low-battery condition. The system will also provide notification of encoder errors or programming changes that may or may not have been performed by authorized personnel.

In addition, utilities may want to know when a particular meter reaches a certain amount of total consumption, as this may trigger them to perform maintenance on that meter. They may say for example that when a 2-inch turbo meter reaches 500,000 gallons, it is time to do a repair or mainte-nance on it. It’s easy to set up an analytical alarm that sends notifications for those conditions.

wso: How do you ensure that customers are ready to use the ana-

lytics optimally?Blackwell: Our trainers work with utilities to explain how the analytics

work and help them set up the alerts they care about. Every utility is a little different. A utility has to be smart about deploying the analytics. If they set them wrong, they could be overwhelmed with alerts. But if they set the alerts correctly and inform the right people to act on them, the analytics can be quite useful.

wso: What other attributes does the analytics system have?Blackwell: The hourly data is very useful for settling billing dis-

putes. Traditionally, when a customer disputes a bill, the utility would go out and test the meter and explain how the meter works, and that’s a lot of time and effort. But when you have proof of how much water the customer used on an hourly basis, it’s much easier to reach a resolution. The cus-tomer may look at the data and say, “Oh, that’s right, my aunt and her three kids were here for a week and they took two showers a day.”

Another benefit is for network management. When a utility installs a fixed network for the first time, there can be a bit of consternation about whether all the endpoints are calling in, and whether all the data collec-tors are online and functioning. We provide a system dashboard with easy-to-understand graphs that show the endpoints and the data collec-tors and the status they’re in.

wso: How has this system been received in the marketplace so far?Blackwell: We have several customers using it, and they are seeing

the value of the analytics. One utility has an area in town with about 10 large hotels. They used to send someone out every day to monitor those meters, because if one of them were to go down, they could lose hundreds or thousands of dollars per day.

With our system in place, they no longer have to send someone out, and no one even has to run reports to check. You tell the system what you’re concerned about, and you don’t have to take any action unless the system tells you to. It’s a system that enables proactive management. It provides vital information utilities need, when they need it, and in the format of their choice, all to improve decision-making. And because it’s web-based, it’s easy to administer and deploy. wso

QUICK-CHANGEARTISTS STORY: TED J. RULSEH

PHOTOGRAPHY: CHip WEinER

The team at a 120 mgd plant in Tampa relies on a rapid settling process, experience, and automation to produce consistent results from variable raw water sources.

As big as it is, the 120 mgd Regional Surface Water Treatment Plant is just part of the supply network for Tampa Bay Water, a wholesale utility serving three counties and three cities on the Gulf side of Florida.

The plant’s operating team has to cope with changeable raw-water quality, and with changes in volume dictated by Tampa Bay Water’s

comprehensive strategy for supply-ing 2.4 million residents in its member jurisdictions.

The plant draws raw water from four sources: The 15.5-billion-gal-lon C.W. Bill Young Regional Res-ervoir, the Alafia River, and two pools in the Tampa Bypass Canal. Helping to keep the finished water supply consistent in quality is a rapid sedimentation process aided by the addition of microsand in the settling basins.

The team also relies on exten-sive automation to meet the En-hanced Treated Water standards in the plant’s operating contract. Veolia Water built the plant in 2002, expanded it in 2010, and operates it under a 20-year agree-ment, according to Mike Kuhn, P.E., Veolia area manager.

Critical need

Tampa Bay Water was formed in 1998 to provide single-source water-supply responsibility for its member governments. At the time, groundwater was the only source of drinking water, and heavy with-drawals were affecting lakes and wetlands. As part of an alternate supply plan, the agency built the reservoir, a seawater desalination plant and the surface water plant to supplement its wellfields.

Water from all these sources is now wheeled around the service territory, the mix of sources depend-ing on cost, seasonal availability and other factors. The surface water plant, designed by the CDM Smith engineering firm, was built with a 66 mgd capacity and expanded in 2010 — with new trains of the

same treatment processes and additional solids handling capacity — to its current 120 mgd capacity. The upgrade also added two 1,250 kW emer-gency generators (Caterpillar) able to power the plant at the 66 mgd rate.

At the heart of the facility is the Actiflo high-rate clarifier process from Veolia Water Solutions & Technologies. In this process, water is floc-culated with ferric sulfate, microsand and polymer. The microsand enhances formation of robust flocs and acts as ballast, significantly reduc-ing settling time. “We achieved significant capital savings because the Actiflo process generally has a footprint about one-fifteenth the size of a conventional settling process with similar capacity,” says Kuhn.

Water enters the plant from a combination of its four sources as dic-tated by Tampa Bay Water and fills two raw-water tanks with 12.5 million gallons total capacity. “In the pipe on the way to Actiflo, we inject sulfu-ric acid for pH adjustment to 4.0 to 4.5, which is optimum for the enhanced coagulation process.

The team at a 120 mgd plant in Tampa relies on a rapid settling process, experience, and automation to produce consistent results from variable raw water sources.

As big as it is, the 120 mgd Regional Surface Water Treatment Plant is just part of the supply network for Tampa Bay Water, a wholesale utility serving three counties and three cities on the Gulf side of Florida.

The plant’s operating team has to cope with changeable raw-water quality, and with changes in volume dictated by Tampa Bay Water’s

comprehensive strategy for supply-ing 2.4 million residents in its member jurisdictions.

The plant draws raw water from four sources: The 15.5-billion-gal-lon C.W. Bill Young Regional Res-ervoir, the Alafia River, and two pools in the Tampa Bypass Canal. Helping to keep the finished water supply consistent in quality is a rapid sedimentation process aided by the addition of microsand in the settling basins.

The team also relies on exten-sive automation to meet the En-hanced Treated Water standards in the plant’s operating contract. Veolia Water built the plant in 2002, expanded it in 2010, and operates it under a 20-year agree-ment, according to Mike Kuhn, P.E., Veolia area manager.

Critical need

Tampa Bay Water was formed in 1998 to provide single-source water-supply responsibility for its member governments. At the time, groundwater was the only source of drinking water, and heavy with-drawals were affecting lakes and wetlands. As part of an alternate supply plan, the agency built the reservoir, a seawater desalination plant and the surface water plant to supplement its wellfields.

Water from all these sources is now wheeled around the service territory, the mix of sources depend-ing on cost, seasonal availability and other factors. The surface water plant, designed by the CDM Smith engineering firm, was built with a 66 mgd capacity and expanded in 2010 — with new trains of the

same treatment processes and additional solids handling capacity — to its current 120 mgd capacity. The upgrade also added two 1,250 kW emer-gency generators (Caterpillar) able to power the plant at the 66 mgd rate.

At the heart of the facility is the Actiflo high-rate clarifier process from Veolia Water Solutions & Technologies. In this process, water is floc-culated with ferric sulfate, microsand and polymer. The microsand enhances formation of robust flocs and acts as ballast, significantly reduc-ing settling time. “We achieved significant capital savings because the Actiflo process generally has a footprint about one-fifteenth the size of a conventional settling process with similar capacity,” says Kuhn.

Water enters the plant from a combination of its four sources as dic-tated by Tampa Bay Water and fills two raw-water tanks with 12.5 million gallons total capacity. “In the pipe on the way to Actiflo, we inject sulfu-ric acid for pH adjustment to 4.0 to 4.5, which is optimum for the enhanced coagulation process. In the Actiflo basin, we can trim the pH with acid if we need to by way of a lower-capacity injection point.”

In the basin, ferric sulfate coagulant is added rather than alum. “Our source water tends to be higher in color and TOC more so than suspended materials,” says Kuhn. “We need to remove precursors for disinfection byproducts (DBPs), which means we need to knock down the TOC in the Actiflo. Our jar testing showed that ferric was much more effective at TOC removal than alum.

“We also have stipulation in our contract to produce a sludge that can be beneficially used.

The sludge is dewatered to about 18 percent solids on six belt presses, four J-Belt units (Siemens) and two Alfa Laval / Ashbrook Simon-Hartley units.

On downstream

After the Actiflo process, the water enters a basin where the pH is adjusted to about 5.5 by addition of lime (with caustic soda as a backup). The water is then fed into ozone contactors equipped with Fuji ozone gen-erators for primary disinfection. “We need tight pH control in the ozone contactors to avoid formation of bromate,” Kuhn reports.

Another pH adjustment to 7.3 follows. The flow then passes to biological downflow filters with a top 4-foot layer of granular activated carbon (top-off material supplied by PICA, a Jacobi Carbons Company), a 6-inch layer of sand, and Leopold underdrains.

“The filters have two purposes,” says Kuhn. “The first is traditional strain-ing to remove turbidity caused by lime addition. The second is chemical

and biological action. TOCs remaining after the Actiflo process are frac-tured by the ozone treatment. At that point you create the opportunity for organics that can be combined with chlorine downstream to form DBPs.

“Instead, we allow the bugs that live on the activated carbon to eat those organics. The bugs are very happy in the warm climate of Florida. They’ve stayed healthy since we began operating the filters back in 2002. We have not seen any decline in the microbe populations or in the effec-tiveness of the treatment.”

Filtered water passes through a set of clearwells and then into a 2-mil-lion-gallon covered chlorine contact chamber, where pH is adjusted with caustic soda and sodium hypochlorite is added for chlorine residual. From there, Tampa Bay Water adds ammonia to form chloramines, and the water then enters a set of three 7.5-million-gallon finished water stor-age tanks for delivery to the water company’s network.

Tampa Bay Water’s needs, the plant may produce 50 million to 80 million gallons on a given day, and from a different mix of sources. Seasonal events affect the water composition.

The primary process adjustment is in the ferric sulfate dosing, which relates mainly to the raw water TOC. Operators stay abreast by analyzing process control samples 24 hours a day. In addition, Tampa Bay Water keeps the plant apprised of changes in volume and the mix of sources, generally a week or so in advance.

T he City of Portland is well known for its environmentally minded citizens and government. This sustainable culture extends to the city’s water bureau, which has been steadily reducing use of elec-tricity and vehicle fuel and installing more solar energy arrays. The

improvements mean big cost savings and lower greenhouse gas emissions.With a staff of 600, the bureau serves 935,000 people in Portland and

19 wholesale-buying communities in Multnomah, Clackamas and Wash-ington counties. The fiscal year 2012-2013 budget is $219 million. The primary water source is the 102-square mile Bull Run Watershed in the Mount Hood National Forest, federally protected land managed strictly for drinking water and hydropower production. The pristine waters enable Portland to bypass filtration.

The water is gravity-fed through 22 miles of pipeline to the city. At the Bull Run Headworks treatment plant, chlorine is added. The water travels five miles to the Lusted Hill treatment plant, allowing time for chlorine absorption. Then ammonia and sodium hydroxide are added to sustain the chlorine level and adjust the pH.

Six reservoirs and 62 storage tanks hold three days’ supply of water; 30 pump stations deliver water to customers. The system delivers an average of 100 mgd. When the watershed has high turbidity or during high water demand, Portland uses a secondary groundwater source of 27 wells that can produce up to 102 mgd.

Energy charter

In February 2010, the bureau adopted an energy management charter that set goals for energy efficiency and renewables. Having all depart-ment directors on board was key to setting things in motion. “There was a high level of buy-in from decision makers on energy management,” says Kavita Heyn, sustainability coordinator. “We developed a culture of energy awareness to encourage efficiency, promote renewable projects and establish a baseline to track and evaluate energy use.”

Staff from resource protection, engineering and operations came together to identify efficiency improvements (especially at pump sta-tions), seek financial incentives to implement and track projects.

Portland has cut energy consumption by using its pumps more effec-tively. Since 2005, operators have been analyzing pump efficiency in the seven largest pump stations, which offer the greatest potential for energy savings. They use baseline data from the SCADA system to determine how long the pumps run and how much water they move.

In stations where there are redundant pumps, the most efficient pumps are used most of the time and are set to fill the tanks during off-peak hours when electricity is least expensive. Besides using information from the SCADA system, operators manually read pump gauges and fine-tune valves, yielding more efficiency.

“Originally our system used altitude valves because the pump sta-tions would pump directly into distribution lines,” says Mia Sabanovic, engineering associate. “Now that we pump into the tanks, the valves have been dialed down, which cuts energy waste. We gained efficiency by doing field inspections.” In the colder months, operators close louver vents and lower thermostat settings in the pump stations. More efficient pump operations saved 1.5 million kWh in 2010.

In 2010, the bureau updated its 15,000-square-foot meter testing shop

to LEED Gold certification by adding energy- and water-saving features. A water recycling system allows reuse of half the water used for meter testing. A 12.24 kW roof-mounted solar photovoltaic array replaces 10 to 25 percent of the building’s utility power and has saved an estimated $3,030 in energy costs.

A solar thermal system provides all necessary hot water for half the year. An energy recovery ventila-tion system captures 75 percent of the heat from exhausted air before it leaves the building. Sensors auto-matically adjust interior lighting when sunlight is present.

The meter shop renovation cost $3.26 million, paid with help from a $30,000 incentive from the Energy Trust of Oregon. The bureau plans to incorporate energy- and water-saving features into two new LEED Gold certified staff buildings under construction.

Besides the solar array at the meter station, the bureau has a 9.8 kW roof-mounted array on the groundwater treatment station that has saved an estimated $749 and six tons of CO2 to date. A 267 kW array at the groundwater pump station includes 1,274 Kyocera solar panels that annu-ally produce almost 300,000 kWh. When the groundwater pumps are operating, the array can fulfill 5 percent of the pump station’s energy need. The array was installed under a seven-year agreement with Ground-water Solar, which paid most of the $2.1 million cost in exchange for rev-enue from power sold to the grid.

Fleet management

To reduce fuel consumption in its 400 passenger and construction vehicles, the bureau has an extensive fleet management program. A data-base tracks each vehicle’s fuel use, miles per gallon and total mileage. “We can see if a vehicle is as efficient as it should be and allocate vehicles with lower miles per gallon to staff members who drive fewer miles,” Heyn says. “We also use engine coolant heaters in 40 of our trucks so they don’t idle to warm up on cold winter days.”

Most vehicles use a biodiesel blend that emits fewer particulates, reduces engine wear and cuts greenhouse gas emissions. Between 2007 and 2011, the bureau reduced its gasoline and diesel use by 16 percent, saving 7 percent of CO2 emissions annually.

Overall, the bureau has built a culture of sustainability by educating staff on the benefits of the efficiency and encouraging participation at every level. “We’ve empowered employees so anyone can share good ideas on how to improve operations,” Sabanovic says. “We share the results of our improvements and include the staff, right down to the operators who installed the pumps. Every operator wants to be the one saving money for the organization.” wso

rounds and does process w sampling. Maintenance and administrative staff generally work the day shift.

Life cycle savings

Kuhn notes that the facility was created under a design-build-operate (DBO) model that is projected to save Tampa Bay Water some $85 million over a 20-year life cycle. The savings result partly from the Actiflo process and its small footprint, saving significantly on land and construction costs, but also from multiple decisions made with an eye toward the long term.

“We looked at this not just as a construction project but as an operat-ing entity,” says Kuhn. “It doesn’t make sense to save $1 today on the cap-ital cost of a project if instead you could spend $2 and as a result save $5 on operations over the project life. A DBO team looks at the full picture because they have skin in the game all the way along.

“We’ve got guarantees on this facility. We guarantee power use, chem-ical use, and the quantities and quality of the water. So we had to be com-petitive to win the project, and we have to be smart about how we operate it over the long term.” wso

Having all depart-ment directors on board was key to setting things in motion. “There was a high level of buy-in from decision makers on energy management,” says Kavita Heyn, sustainability coordinator. “We developed a culture of energy awareness to encourage efficiency, promote renewable projects and establish a baseline to track and evaluate energy use.”

Staff from resource protection, engineering and operations came together to identify efficiency improvements (especially at pump sta-tions), seek financial incentives to implement and track projects.

Portland has cut energy consumption by using its pumps more effec-tively. Since 2005, operators have been analyzing pump efficiency in the seven largest pump stations, which offer the greatest potential for energy savings. They use baseline data from the SCADA system to determine how long the pumps run and how much water they move.

In stations where there are redundant pumps, the most efficient pumps are used most of the time and are set to fill the tanks during off-peak hours when electricity is least expensive. Besides using information from the SCADA system, operators manually read pump gauges and fine-tune valves, yielding more efficiency.

“Originally our system used altitude valves because the pump sta-tions would pump directly into distribution lines,” says Mia Sabanovic, engineering associate. “Now that we pump into the tanks, the valves have been dialed down, which cuts energy waste. We gained efficiency by doing field inspections.” In the colder months, operators close louver vents and lower thermostat settings in the pump stations. More efficient pump operations saved 1.5 million kWh in 2010.

Building efficiencies

In 2010, the bureau updated its 15,000-square-foot meter testing shop

Creating a CulturePortland Water Bureau reduces costs and greenhouse gas emissions through electrical efficiencies and a smart fleet management program

By LISA BALCERAk

to LEED Gold certification by adding energy- and water-saving features. A water recycling system allows reuse of half the water used for meter testing. A 12.24 kW roof-mounted solar photovoltaic array replaces 10 to 25 percent of the building’s utility power and has saved an estimated $3,030 in energy costs.

A solar thermal system provides all necessary hot water for half the year. An energy recovery ventila-tion system captures 75 percent of the heat from exhausted air before it leaves the building. Sensors auto-matically adjust interior lighting when sunlight is present.

The meter shop renovation cost $3.26 million, paid with help from a $30,000 incentive from the Energy Trust of Oregon. The bureau plans to incorporate energy- and water-saving features into two new LEED Gold certified staff buildings under construction.

Besides the solar array at the meter station, the bureau has a 9.8 kW roof-mounted array on the groundwater treatment station that has saved an estimated $749 and six tons of CO2 to date. A 267 kW array at the groundwater pump station includes 1,274 Kyocera solar panels that annu-ally produce almost 300,000 kWh. When the groundwater pumps are operating, the array can fulfill 5 percent of the pump station’s energy need. The array was installed under a seven-year agreement with Ground-water Solar, which paid most of the $2.1 million cost in exchange for rev-enue from power sold to the grid.

Fleet management

To reduce fuel consumption in its 400 passenger and construction vehicles, the bureau has an extensive fleet management program. A data-base tracks each vehicle’s fuel use, miles per gallon and total mileage. “We can see if a vehicle is as efficient as it should be and allocate vehicles with lower miles per gallon to staff members who drive fewer miles,” Heyn says. “We also use engine coolant heaters in 40 of our trucks so they don’t idle to warm up on cold winter days.”

Most vehicles use a biodiesel blend that emits fewer particulates, reduces engine wear and cuts greenhouse gas emissions. Between 2007 and 2011, the bureau reduced its gasoline and diesel use by 16 percent, saving 7 percent of CO2 emissions annually.

Overall, the bureau has built a culture of sustainability by educating staff on the benefits of the efficiency and encouraging participation at every level. “We’ve empowered employees so anyone can share good ideas on how to improve operations,” Sabanovic says. “We share the results of our improvements and include the staff, right down to the operators who installed the pumps. Every operator wants to be the one saving money for the organization.” wso

Peristaltic pump improves fluoride injection accuracy

ProblemPulsating-type diaphragm metering pumps were injecting fluoride at the Jones Ferry Road Water

Treatment Plant in North Carolina. The fluoride treatment system at the 20 mgd plant requires one pri-mary pump and one backup pump controlled by 4-20 mA and monitored by a SCADA system. The injec-tion rate is 63 ml/min. Operations supervisor Dusty Martin, with the Orange Water and Sewer Authority, had trouble maintaining accurate and consistent fluoride residuals using the diaphragm pumps, which also were affected intermittently by air pockets that entered the system through the day tank.

Solution

Martin installed a Flex-Pro peristaltic pump from Blue-White Industries. The pump easily hooked into the SCADA system; continuous mon-itoring confirms that the exact amount of chemical is being injected and residual levels are more consistent.

Result: The peristaltic pumps have been in operation for more than six years with very low maintenance. “I highly recommend a peristaltic pump for fluoride injection,” says Martin. “It has proven very reliable and accurate for many chemical injection applications associated with water treatment.” 714/893-8529; www.blue-white.com.

UV disinfection system installed on an abbreviated schedule

ProblemTo meet strict deadlines to implement California Department of Public Health and U.S. EPA LT2

rules for drinking water disinfection, the San Francisco Public Utility Commission (SFPUC) needed to accelerate design, construction and installation of the Tesla Water Treatment Facility, which draws unfiltered water from the Hetch-Hetchy reservoir in northern California.

Solution

The SFPUC used a collaborative design-build construction model and installed a newly designed uV disinfection system engineered by Calgon Carbon Corporation, consisting of 12 Sentinel 48 Chevron UV reactors. Each reactor has nine 20 kW lamps oriented in a chevron formation for effec-tive UV dosing with the least power consumption. The system was designed to function without human supervision except for periodic calibration.

Result: The project brought the Tesla Facility to full compliance with all state and federal public health mandates in about half the time typi-cally required for similar design-bid-build projects, and came in under budget. The plant is the largest of its kind in California, treating 315 mgd and serving more than 2.5 million people. 800/422-7266; www.calgoncarbon.com.

Test confirms effectiveness of PAA disinfectant

ProblemA water treatment plant in Steubenville, Ohio, needed a cost-effective water disinfection

method that would not generate chlorinated byproducts.

SolutionIn a little more than a month, solvay Chemicals conducted independent plant-scale

trials using Proxitane WW-12 peracetic acid (PAA). PAA is a faster-acting disinfectant than chlorine-based chemicals, does not generate harmful DBPs even if overdosed and can be econom-ically retrofitted or work in series with an existing disinfection system. The plant was operating at 5 to 8 mgd with a capacity of 13.5 mgd.

Result: PAA dosage never exceeded 1.5 ppm, and the residual averaged 0.4 ppm but did not exceed 1 ppm. PAA feed was flow-paced, CBOD remained constant and pathogen control was always within the permit limits. The test was a success. 800/765-8292; www.solvaychemicals.us.

New chlorinator improves efficiency at award-winning plant

ProblemThe Village of Montpelier, Ohio, was updating its water treatment facility and wanted to

replace the gas chlorinator equipment. The village originally used a gas chlorinator that needed continual work on its heads, would leak or stick often and needed replacement com-ponents. The staff lacked time to babysit the chlorine tank when it was about to go empty.

Solution

The village chose the Regal gas Chlorinator from Chlorinators Incorporated. When one tank goes empty, it automatically switches to the standby tank and maintains a constant feed rate. When used with Regal SmartValves, the system is flow proportional, allowing the flow to be adjusted from 1,400 gpm in summer to 1,000 gpm in winter.

Result: The system helped the village eliminate downtime, save money and reduce labor. Montpelier has won the gold medal at the annual Inter-national Water Tasting Event in Berkeley Springs, W.V., three times. 772/288-4854; www.regalchlorinators.com.

Ozone disinfection and pretreatment solves taste and odor issues

ProblemThe City of Bécancour, Quebec, Canada, needed a replacement for its older air-based ozone unit.

While the unit was still operational, the city struggled with removing color and total organic carbon (TOC) and reducing disinfection byproducts (DBPs) in finished water.

Solution

Pinnacle Ozone solutions provided a complete ozone treatment system. The Pinnacle Peak Series ozone generator system provides ozone to both the pretreatment and disinfection process steps at the plant via a single integrated system. Working with one provider simplified design and installation; the company handled zone generation, oxygen supply, dual ozone injection skids and com-plete process controls. Other benefits included a significantly reduced footprint, quieter operation and lower maintenance.

Result: By employing Pinnacle’s Ozone-On-Demand controls, the plant maintains constantly high ozone concentrations of 10 percent across the full range of operating conditions. When combined with the ozone generators, this significantly reduces total power and operating costs. 321/205-1717; www.pinnacleozone.com.

Ozone system clears up taste issues

ProblemThe water reaching faucets in Waco, Texas, had such foul taste and odor that residents considered it

undrinkable. The problem originated from high nutrient loadings in runoff from dairy farms in the water-shed above Lake Waco, the city’s raw water source. The contaminants triggered explosive algae blooms and pathogen spikes. Costly chemical treatment added to the process chains failed to suppress the taint.

Solution

A $55 million process upgrade designed by CH2M Hill and The Wallace Group resolved the problem by adding advanced pretreatment clarification, complemented by a 90 mgd PDO1000 ozone disinfection system from WeDeCO – a Xylem Brand. The dual-purpose ozone system provides primary disinfection without harmful chemical byproducts, ahead of mandatory dose of chlorination at release to the distribution system.

Result: The ozone system oxidizes any residual nutrients and delivers maximum disinfection. The taste and odor in the water are gone, along with the complaints. 704/409-9700; www.xyleminc.com. (Continued on page 35)

Leak detection equipment yields savings

ProblemWith 75 miles of pipeline installed before 1950 and the unbilled water rate at 34 percent in 2010, operations manager Richard McDaniel of the Rock-

dale County Water Resource in Conyers, Ga., saw a need to monitor the aging water mains and valves. The department’s budget offered limited leeway.

SolutionIn 2011, after research and competitive bidding, McDaniel purchased 370 Permalog+

acoustic leak noise loggers, a Patroller II drive-by data collection device, a triCorr touch real-time leak noise correlator, a soundsens “i” advanced correlating logger system and an Xmic ground microphone from Fluid Conservation systems. The prod-ucts work together to analyze leak noise from water lines, transmit the data to mobile collection units, and pinpoint leaks to minimize repair time and cost. McDaniel and his team also com-pleted extensive product training to ensure proper operation.

Result: Within the first year, Rockdale County Water found more than 50 leaks responsible for losses of 248,000 gpd. At a cost of $1 per 1,000 gallons of water, the program has already saved customers more than $90,000 per year. The agency plans to continue expanding Permalog+ cov-erage of its distribution network. 800/531-5465; www.fluidconservation.com. wso

In the Town of Windsor, water con-servation has been a challenge for decades, but in 2012 this small Northern California community

hit on a remedy that already has won national recognition.

Launched in August 2012, the Windsor Efficiency PAYS program helps pre-qualified residents make upgrades that improve water and energy efficiency in their homes. They pay a surcharge on their water bills after the upgrades until the costs of their improvements are repaid.

Paul Piazza, water conservation program coordinator, says that even with the surcharges in place, resi-dents should see an immediate reduction in their bills. When

improvements are paid off, the surcharges will end and the sav-ings will be even greater.

Everyone wins

“The innovation the PAYS program brings is that it’s attrac-tive to everyone, even customers who don’t participate,” says Piazza. “The participants ultimately pay for the full program, but they are saving money, too. It actually ben-efits everybody, because even the non-participants benefit from the lower cost of maintaining capacity in the future.”

Reducing demand is important for Windsor because it is nearing capacity during peak demand months. The town created the pro-gram with financial assistance from the Sonoma County Regional Climate Protection Authority and the U.S. Department of Energy Better Buildings Program, but it uses its own reserves as the seed capital for the home improvements.

In January, Windsor Efficiency PAYS was one of 12 projects recog-nized by the American Council for an Energy-Efficient Economy and the Alliance for Water Efficiency for programs that save both energy and water. Of 450 programs nation-wide, five were deemed Exemplary Programs, and Windsor was one

of seven recognized as Programs of Promise.

Not like rebates

Windsor Efficiency PAYS dif-fers from traditional rebate programs in several ways. First, participants must qualify. “We have to qualify them based on their potential sav-ings,” Piazza says. “We have to be sure that their savings will pay for the upgrades.” In most rebate pro-grams, water customers simply have to prove that they installed

Water-efficient landscaping is a part of the Town of Windsor’s efforts tolimit water consumption.

The efficiency program’s basic level includes installing water-saving toilets, showerheads and faucet aerators.

efficient fixtures or appliances. The town has set a goal of

qualifying 2,000 customers in the first year and an overall goal of enrolling half of the 8,000 resi-dential customers. “At that point we’ll probably be at our saturation point of customers who can qual-ify,” Piazza says.

Participants enter the program at the basic level, which covers the up-front costs of installing water-saving showerheads, toilets and aer-ators. The fixtures that qualify exceed the efficiency standards that gov-ern the Windsor rebate program.

Once the equipment is installed, or if the home’s existing fixtures already meet program standards, owners can qualify for “basic plus measures” that help with the instal-lation of drought-resistant land-scaping, high-efficiency washing machines and compact fluorescent lights. A third step involves “co-pay measures,” requiring partial up-front investment by customers for high-efficiency refrigerators, on demand hot-water recirculation pumps and high-efficiency clothes dryers.

At every step, the town reviews applications to ensure that the savings will exceed the bill sur-charges. If a customer moves from a house or apartment before the upgrades are paid for, that per-son’s obligation ends; the new res-ident gets the remaining savings and makes the remaining sur-charge payments.

room to grow

Piazza says the program may expand: “There is the potential to roll this into our commercial side, not so much based on indoor usage, but on landscape.” Water customers who don’t want to take part in or can’t qualify for the PAYS program have other ways to save water and money.

Under the Water Smart Home Program residents can have a water conservation representative per-form an on-site assessment. Toi-lets, faucets and showerheads are checked for leaks and tested for water consumption. Where appro-priate, the town provides free low-flow replacement showerheads and

faucet aerators. Rebates are avail-able for replacing 3.5-gallon-per-flush toilets.

Irrigation systems are inspected for leaks and are given a system performance check. Based on the results, the utility team creates a site-specific irrigation schedule for spring, summer and fall and provides water-saving recommen-dations for tuning up the system. A Water Efficient Landscapes (WEL) program offers rebates for upgrading to water-saving sprin-kler technology or for removing turf grass.

Commercial and business water users also can save water and money:

• The Town of Windsor and the Sonoma County Business Environmental Alliance part-ner to offer commercial, indus-trial and institutional users free water-use assessments conducted by an independent contractor, who provides a voluntary action plan.

• The town offers free land-scape water-use surveys.

• Large users can get rebates up

to $150 per toilet for replac-ing 3.5-gallon-per-flush toi-lets with units that use 1.28 gallons per flush or less.

• The Water Efficient Land-scapes Rebate Program pro-vides up to $650 for commercial mixed-use meter accounts or $2,500 for dedicated irri-gation meter accounts when customers remove turf or upgrade with new water-sav-ing irrigation equipment.

• The Water Efficient Tech-nologies Rebate program can provide up to $25,000 for pro-cess and equipment changes that save at least 50,000 gal-lons per year. wso

Someone wise once said nothing ever goes wrong — until it does. The captain of the cruise ship Carnival Triumph probably thought nothing would go wrong with his 102,000-ton ship when he got underway from Galveston, Texas on Feb. 7 for a four-day cruise to

Cozumel, Mexico. Inspection reports by the U.S. Coast Guard on the condition of back-

up generators and lifeboats raised few red flags. The same goes for the sanitation inspection report by the U.S. Centers for Disease Control and Prevention. Yet, something went wrong, and the 4,200 passengers and crew became poster children for what happens when disaster strikes. Some took it in stride. Others sued.

A fuel line ruptured, crippling the cruise ship. The ruptured line caused an engine room fire, and that caused a complete loss of power. Propulsion was lost. Toilets wouldn’t flush. Elevators and air conditioning didn’t work. Food service was severely restricted. The ship had to be towed to Mobile, Ala.

Are you ready?

What about our utilities? Are we prepared to deal with a complete loss of power? Or a former employee who comes with a gun and methodically shuts down treatment and alarm systems? Or a major main break that causes a giant sinkhole?

An emergency you are unprepared for can ruin your day and your career. Being prepared can make you look brilliant. The basics aren’t that hard. Some states require utilities to have emergency plans on hand. Colorado, for example, requires plants to submit an overall facility operating plan.

If a facility doesn’t have an overall operating plan, it must submit a discussion or outline of the emergency response program used at the facility. That submission must include:

• A description of alternate power sources• A discussion of alarm systems installed at the facility, including

any remote transmission of alarms• A description of the chain of command in emergencies• Any other information needed for emergency responseThe facility also must submit a copy or description of its staffing plan.

The plan must include the number of operators and their certification levels, plus operating personnel coverage during weekdays, weekends and holidays.

The softer sideFiguring out the operating emergencies to plan for and creating plans

for them is relatively straightforward. One approach would be to think, “What’s the worst thing that could happen to us? What is the likelihood of that happening?” Write it down, and then do the same thing for several other potentially disastrous events.

With the event identification done, begin to think outside the fence-line to flesh out the plan. What happens if you have a chlorine leak? That kind of event affects people both within and outside the plant. Your abil-ity to disinfect is likely compromised, and your employees’ and neigh-bors’ health may be jeopardized.

Panic may set in among your neighbors. The media will descend upon

you. Emergency response agencies, firefighters, hazardous materials han-dlers and police will overrun your facility, and you will be one among many agencies involved in the situation. Questions from the media will come thick and fast. Confusion will reign.

Facilities can prepare for the non-technical requirements of handling an emergency by thinking beyond the control room. At the management level, these preparations include:

• List everyone who would be recalled to help deal with an emergency. Include physical address, desk phone, cellphone, home phone, remote location phone (such as a getaway cabin) and email.

• Develop an incident command model for emergencies. The Incident Command System is a good model for which there is much support from the federal government. You can find basic information about it at http://www.fema.gov/incident-command-system#item1.

• Spell out in writing who has the authority to activate the emergency response plan.

• Develop a plan to notify next-of-kin of employees who have been hurt or killed. Make sure you notify the family first. Do not let someone else do it.

When Will It Be Your Turn?Almost every organization has an emergency sooner or later. The best way to make sure you survive it intact is to plan for the worst — today.

BY STeve FrAnk, APr

crisis management experts say there are only two types of organizations: Those that have had a crisis, and those that will. Planning for what to do

in an emergency doesn’t mean you are planning for things to go wrong. It makes you a winner.

• Sign a WARN (Water/Wastewater Agency Response Network) agree-ment so you can borrow people and equipment from other utilities in an emergency.

• Make sure someone on your recall list has enough spending author-ity to rent equipment you might need (like power generators) or hire emergency repair crews.

handling the press

The next several items will help you plan to deal with the media. Depend-ing on the seriousness of the emergency, you could have zero to hundreds of media people on hand, all demanding your immediate attention.

• Identify and appoint in writing an emergency spokesperson or pub-lic information officer (PIO), even if you don’t normally have one. The PIO must not be the person who will lead the operational side of the recovery effort.

• Designate a back-up for the emergency PIO — people get sick and go on vacation.

• Get media training for the PIO and backup, plus the top two opera-tional officials who might serve as incident managers.

• Spell out in writing who the PIO must get approval from to release information.

• Spell out in writing who will contact government officials.• Compile a phone, cellphone, email and fax list of news media in

your town and in nearby large cities. The media can help you notify stakeholders about what to do to avoid danger when lives are at risk.

• Decide where your media holding area will be. You will need chairs and tables, phones, electricity, Wi-Fi access and a place to hold press briefings.

• Write a one-page fact sheet about your utility. Include the head-quarters location, the area it serves, how many people are served, what the annual budget is, how many employees, amount of water treated daily, how many miles of distribution lines, the last major upgrade, history and other basics. This is much easier to do when there is no emergency at hand.

• Conduct a tabletop exercise with operators to talk through some-thing like a complete loss of electrical power or other emergency. Include the communication component and local emergency man-agement officials in the exercise.

Practice is extremely important. That’s when it’s OK to make a mis-take and learn from it.

Someone wise once said nothing ever goes wrong — until it does. The captain of the cruise ship Carnival Triumph probably thought nothing would go wrong with his 102,000-ton ship when he got underway from Galveston, Texas on Feb. 7 for a four-day cruise to

Cozumel, Mexico. Inspection reports by the U.S. Coast Guard on the condition of back-

up generators and lifeboats raised few red flags. The same goes for the sanitation inspection report by the U.S. Centers for Disease Control and Prevention. Yet, something went wrong, and the 4,200 passengers and crew became poster children for what happens when disaster strikes. Some took it in stride. Others sued.

A fuel line ruptured, crippling the cruise ship. The ruptured line caused an engine room fire, and that caused a complete loss of power. Propulsion was lost. Toilets wouldn’t flush. Elevators and air conditioning didn’t work. Food service was severely restricted. The ship had to be towed to Mobile, Ala.

Are you ready?

What about our utilities? Are we prepared to deal with a complete loss of power? Or a former employee who comes with a gun and methodically shuts down treatment and alarm systems? Or a major main break that causes a giant sinkhole?

An emergency you are unprepared for can ruin your day and your career. Being prepared can make you look brilliant. The basics aren’t that hard. Some states require utilities to have emergency plans on hand. Colorado, for example, requires plants to submit an overall facility operating plan.

If a facility doesn’t have an overall operating plan, it must submit a discussion or outline of the emergency response program used at the facility. That submission must include:

• A description of alternate power sources• A discussion of alarm systems installed at the facility, including

any remote transmission of alarms• A description of the chain of command in emergencies• Any other information needed for emergency responseThe facility also must submit a copy or description of its staffing plan.

The plan must include the number of operators and their certification levels, plus operating personnel coverage during weekdays, weekends and holidays.

The softer sideFiguring out the operating emergencies to plan for and creating plans

for them is relatively straightforward. One approach would be to think, “What’s the worst thing that could happen to us? What is the likelihood of that happening?” Write it down, and then do the same thing for several other potentially disastrous events.

With the event identification done, begin to think outside the fence-line to flesh out the plan. What happens if you have a chlorine leak? That kind of event affects people both within and outside the plant. Your abil-ity to disinfect is likely compromised, and your employees’ and neigh-bors’ health may be jeopardized.

Panic may set in among your neighbors. The media will descend upon

you. Emergency response agencies, firefighters, hazardous materials han-dlers and police will overrun your facility, and you will be one among many agencies involved in the situation. Questions from the media will come thick and fast. Confusion will reign.

Facilities can prepare for the non-technical requirements of handling an emergency by thinking beyond the control room. At the management level, these preparations include:

• List everyone who would be recalled to help deal with an emergency. Include physical address, desk phone, cellphone, home phone, remote location phone (such as a getaway cabin) and email.

• Develop an incident command model for emergencies. The Incident Command System is a good model for which there is much support from the federal government. You can find basic information about it at http://www.fema.gov/incident-command-system#item1.

• Spell out in writing who has the authority to activate the emergency response plan.

• Develop a plan to notify next-of-kin of employees who have been hurt or killed. Make sure you notify the family first. Do not let someone else do it.

When Will It Be Your Turn?Almost every organization has an emergency sooner or later. The best way to make sure you survive it intact is to plan for the worst — today.

How can a small water company set up a SCADA system that pro-vides and stores information to support intelligent decisions and control the water system without breaking the budget?

I faced that question two and a half years ago when asked to take over as facilities manager of Gill Creek Mutual Water Company, serving about 86 homes near Geyserville, Calif., when the current manag-ers retired. Having served as a volunteer assistant manager and on the board of directors, I knew the company faced some challenges but had some positive qualities.

On one hand, maintenance and repairs ate up 32 to 45 percent of the budget, our electricity costs were high because we were unable to sync with our utility’s time-of-day rate schedule, and we often depended on customers to tell us when we had a problem such as no water or water overflowing a tank.

On the other hand, we had ample water storage capacity, good-quality groundwater, and a good relationship with regulators and customers. We needed a way to monitor the system and control the equipment.

A traditional SCADA system would have cost $100,000 to set up, and more to maintain and administer — clearly beyond our budget. I called my brother Paul at XiO, specializing in cloud-based automation. He said his company could collect information about our company, store it in the cloud, and use it to make decisions to help control our pumping, ulti-mately saving us money.

While most of the cost of traditional SCADA is in hardware and soft-ware, a cloud-based system is stored on servers shared with other users, and the costs are also shared. Today, we have a cloud-based control sys-tem that runs all our equipment and tells me more about our fairly com-plex water company than I could have imagined. Our total SCADA system has cost less than $25,000.

Each morning when I check our system from a laptop, a smartphone or an iPad, I see that the pumps filled our tanks before electric rates went up at 8:30 a.m. If our system uses more water than expected during the day, the system decides when to run the pumps to avoid peak rates. Also in place is an alarm system that can email maintenance people to report minor anomalies or phone me at any hour if immediate action is needed.

Getting started: communication

We needed to link our three locations: the wells, the pumphouse with contact tank and the hilltop tank reservoir. For years we had used five dedicated phone lines to communicate on/off information between the pumps and tanks. Floats in the tanks directed the pumps to start and stop. One phone line was hooked to an auto-dialer that was less than reli-able in sending accurate alarms. The usual replacement for a phone line is to use radios that work with the SCADA system and use serial modems, which means extra costs with every hardware or software change.

Paul recommended a fairly new technology — reliable and low-cost IP radios, which are used to provide Internet access in rural areas. These smart 900 MHz radios establish a local area network (LAN), but we needed line-of-sight.

My first job was to establish radio contact between the pumps and wells. After using GPS to identify four possible transmitter/receiver loca-tions, we plugged the data into Google Earth and found that we had line-of-sight down a canyon if we could locate one of the pumphouse radios on a hill above the pumphouse. We could then run a cable 150 feet to the pumphouse, which would contain most of our control equipment.

We bolted the radios to 1 1/2-inch galvanized pipe and secured them with guy wires. (If we had been confident that the radio network would perform as well as it finally did, we would have used telescoping towers to make maintenance easier for the two radios that stand 30 feet above the ground.) The wells were in direct line-of-sight from the pumphouse, so that hookup was easy.

System monitoring

Phase one was to monitor the system without changing the controls to see what was happening daily. We installed pressure transducers to mea-sure the water level in the upper tank, the intermediate surge (contact) tank and the two wells. The well transducers hang from stainless steel cables two feet above the submersible pumps, but the tank transducers are at the bottom, outside the tanks, connected to the tanks by narrow rodent-resistant tubing.

Overview of the Gill Creek water system.

SCADA display showing a normal hypochlorite level.

The transducer, in a PVC housing (Figure 2), sends the signal via a cable to our module in a watertight box (a field-installable unit, or FIU) fastened to the radio tower. The transducers measure the depth of water above the sensor, and the FIU converts that signal to feet and inches. We can measure changes of less than 1/8 inch over the 15-foot tank height. Since we had 110 VAC power at the upper tank, we just plugged in, but since the module and radio together use less than 10 watts, we could have used a solar supply.

We also installed electronic pulse generators on our McCrometer flowmeters at the wells and at the output of our lift pumps, and tied them into the nearby FIUs. Our last monitoring station was in the chlorination room. We rebuilt a free chlorine monitor (Hach CL-17) and plugged it into the FIU in the pump house, and also began reading the level of sodium hypochlorite in a 40-gal-lon mix drum using a noncontact gauge.

Then we hooked up the system to the Internet using a cellular modem that plugged directly into the Soft-I/O module. There is only one control component inside the FIU. We can now watch our system from any laptop, iPad or smartphone.

What we learned from monitoring surprised us:Our wells were in good condition after 40 years. The well-level sen-

sors told us that even after the pumps ran for several hours, the water level dropped only 16 feet, leaving at least 66 feet of water over the pumps. Recovery after pumping took only minutes.

For years, the floats in our 84,000-gallon upper tank were only allow-ing 5,000 gallons of outflow before the pumps ran to refill the tank — the result of an error in how the floats were set.

Both well pumps typically ran together to keep up with the 30 hp lift

pump, causing the well pumps to cycle frequently while the lift pump was running. The well pumps seemed to fight each other, and the result-ing flow rate was barely higher than if the faster well pump had run alone. We found that one well pump could do the job without cycling, saving sig-nificant energy and wear on both pumps. For long pump runs, we could turn on the second well pump to finish the cycle without shutting down the lift pump.

Since all of our pumps started at random times during the day depending on float height, we often paid the highest electric rates. In summer, about half our energy cost came from pumping about 30 percent of the water.

The sodium hypochlorite mix level dropped slowly even when the well pumps were not running. A couple of bad check valves created a vac-uum in the pipeline from the wells when water drained back into the well. That sucked chlorine through the metering pump(s) and allowed an extra gallon or so of disinfectant to be drawn into the well pipe each day. This was easily rectified and did not cause a hazard, but we would not have known about it without the controls.

By constantly monitoring the electricity used by each pump, we found that the newer well pump cost us about 50 percent more per 1,000 gallons than the older pump. We also know that one of our lift pumps is much less efficient than we thought.

Several times per month, a flaw in the old startup routine would abruptly stop the lift pumps before the slow-closing Bermad valve shut down. The resulting “hammer” subjected the pipes to damage, and the alternate lift pump often failed to start automatically after the other pump stopped, causing the system to run out of water.

If one of the lift pumps failed to start, the lift pump would shut down and the entire system would lock up until an operator went on site to reset the pumps. During that time, the main tank was heading to empty.

Cloud system startup

We had found a number of areas needing fairly simple fixes. Now it was time to turn the system over to the new controls. The goal is to pro-vide uninterrupted service to the community, so we maintained the abil-ity to run all pumps manually if necessary.

We connected the well pumps so that either could run separately or both could run together to keep the intermediate (contact) tank supplied with water for the lift pumps. This independent operation caused a bit of a problem: Because the flow rate varies greatly depending upon which pump (or pumps) are running, the amount of sodium hypochlorite needed varies similarly. In addition, the only operational flowmeters were nearly a mile from the pumphouse at the wells.

How can a small water company set up a SCADA system that pro-vides and stores information to support intelligent decisions and control the water system without breaking the budget?

I faced that question two and a half years ago when asked to take over as facilities manager of Gill Creek Mutual Water Company, serving about 86 homes near Geyserville, Calif., when the current manag-ers retired. Having served as a volunteer assistant manager and on the board of directors, I knew the company faced some challenges but had some positive qualities.

On one hand, maintenance and repairs ate up 32 to 45 percent of the budget, our electricity costs were high because we were unable to sync with our utility’s time-of-day rate schedule, and we often depended on customers to tell us when we had a problem such as no water or water overflowing a tank.

On the other hand, we had ample water storage capacity, good-quality groundwater, and a good relationship with regulators and customers. We needed a way to monitor the system and control the equipment.

A traditional SCADA system would have cost $100,000 to set up, and more to maintain and administer — clearly beyond our budget. I called my brother Paul at XiO, specializing in cloud-based automation. He said his company could collect information about our company, store it in the cloud, and use it to make decisions to help control our pumping, ulti-mately saving us money.

While most of the cost of traditional SCADA is in hardware and soft-ware, a cloud-based system is stored on servers shared with other users, and the costs are also shared. Today, we have a cloud-based control sys-tem that runs all our equipment and tells me more about our fairly com-plex water company than I could have imagined. Our total SCADA system has cost less than $25,000.

Each morning when I check our system from a laptop, a smartphone or an iPad, I see that the pumps filled our tanks before electric rates went up at 8:30 a.m. If our system uses more water than expected during the day, the system decides when to run the pumps to avoid peak rates. Also in place is an alarm system that can email maintenance people to report minor anomalies or phone me at any hour if immediate action is needed.

Getting started: communication

We needed to link our three locations: the wells, the pumphouse with contact tank and the hilltop tank reservoir. For years we had used five dedicated phone lines to communicate on/off information between the pumps and tanks. Floats in the tanks directed the pumps to start and stop. One phone line was hooked to an auto-dialer that was less than reli-able in sending accurate alarms. The usual replacement for a phone line is to use radios that work with the SCADA system and use serial modems, which means extra costs with every hardware or software change.

Paul recommended a fairly new technology — reliable and low-cost IP radios, which are used to provide Internet access in rural areas. These smart 900 MHz radios establish a local area network (LAN), but we needed line-of-sight.

My first job was to establish radio contact between the pumps and wells. After using GPS to identify four possible transmitter/receiver loca-tions, we plugged the data into Google Earth and found that we had line-of-sight down a canyon if we could locate one of the pumphouse radios on a hill above the pumphouse. We could then run a cable 150 feet to the pumphouse, which would contain most of our control equipment.

We bolted the radios to 1 1/2-inch galvanized pipe and secured them with guy wires. (If we had been confident that the radio network would perform as well as it finally did, we would have used telescoping towers to make maintenance easier for the two radios that stand 30 feet above the ground.) The wells were in direct line-of-sight from the pumphouse, so that hookup was easy.

System monitoring

Phase one was to monitor the system without changing the controls to see what was happening daily. We installed pressure transducers to mea-sure the water level in the upper tank, the intermediate surge (contact) tank and the two wells. The well transducers hang from stainless steel cables two feet above the submersible pumps, but the tank transducers are at the bottom, outside the tanks, connected to the tanks by narrow rodent-resistant tubing.

Overview of the Gill Creek water system.

SCADA display showing a normal hypochlorite level.

The transducer, in a PVC housing (Figure 2), sends the signal via a cable to our module in a watertight box (a field-installable unit, or FIU) fastened to the radio tower. The transducers measure the depth of water above the sensor, and the FIU converts that signal to feet and inches. We can measure changes of less than 1/8 inch over the 15-foot tank height. Since we had 110 VAC power at the upper tank, we just plugged in, but since the module and radio together use less than 10 watts, we could have used a solar supply.

We also installed electronic pulse generators on our McCrometer flowmeters at the wells and at the output of our lift pumps, and tied them into the nearby FIUs. Our last monitoring station was in the chlorination room. We rebuilt a free chlorine monitor (Hach CL-17) and plugged it into the FIU in the pump house, and also began reading the level of sodium hypochlorite in a 40-gal-lon mix drum using a noncontact gauge.

Then we hooked up the system to the Internet using a cellular modem that plugged directly into the Soft-I/O module. There is only one control component inside the FIU. We can now watch our system from any laptop, iPad or smartphone.

What we learned from monitoring surprised us:Our wells were in good condition after 40 years. The well-level sen-

sors told us that even after the pumps ran for several hours, the water level dropped only 16 feet, leaving at least 66 feet of water over the pumps. Recovery after pumping took only minutes.

We were saved by the LAN, which makes the combined flow rates of the two wells readily available at the pumphouse. Within seconds of a well pump starting, the signal from the McCrometer flowmeters at the wells and a flow switch in the disinfection room allow the local Soft-I/O module to calculate how much sodium hypochlorite the metering pump(s) should inject into the pipe to the intermediate (contact) tank. A Hach CL-17 downstream of the intermediate tank tells us the free chlorine level as water is pumped to the main reservoir up the hill.

We set up the 30 hp lift pumps to follow certain priorities:1. Keep the tanks full regardless of electrical costs during high-fire-

danger times.2. Pump water when electrical rates are lowest, if practical.3. If one lift pump fails to start, or stops during its normal run, trig-

ger an alarm so that the other pump automatically starts and keeps the tanks full.

Alarms are also sent:• If the level of available sodium hypochlorite is getting low• If the chlorine analyzer shows a high or low free chlorine reading• If water levels are either higher or lower than a setpoint in any tank• If any pump fails to start or maintain flow• If the cloud servers lose contact with one of the sites

ResultsBy taking advantage of off-peak electricity, we reduced our electric

bill by about 25 percent. Some savings came from running the more effi-cient pump preferentially. Several times we detected system leaks very quickly, resulting in a tight system in which we billed about 99 percent of the water pumped.

More than once, we detected when an operator forgot to fill the sodium hypochlorite tank. We were able to see the outage graphically and refill

the drum before untreated water was pumped into the system. Since the cloud-based monitoring system has been active, we have had no out-of-water events.

I have become accustomed to picking up my smartphone or going to my desk and in a minute knowing that all is well on the system. Every event the SCADA system has recorded in the past year is stored in the cloud and is available, without taking up space on a local computer.

The bottom line is that the cloud-based SCADA system helps us anticipate problems rather than react, and thus our maintenance and repair costs have dropped dramatically. Looking at our energy savings and the reduction in emergency service calls, I can say we have made our small water district a better organization. It has certainly made my life easier!

clean. The Red is subject to wide variations in organic matter and hard-ness, related to weather and the nature of the watershed, Hall observes. Normal flows range from about 3,000 to 5,500 cubic feet per second.

The main feeder streams include the Otter Tail River, with generally high water quality; the Bois de Sioux River, with very poor water quality; and the Wild Rice River. “Every river system that feeds the Red is vari-able, depending on how much rain we’re getting at the time,” says Hall.

At the old treatment plant, which used lime and soda ash softening and dual-media filtration, the wide source water variations overwhelmed the process. At the time, the source water included about 60 percent river and 40 percent well water. Potassium permanganate and sometimes

activated carbon were fed at the river pumping station, but at times that wasn’t enough. When taste and odor problems arose, complaint calls came in bunches.

Reliable processThe MWH engineering firm (then known as Montgomery Watson)

designed the new treatment plant. The Moorhead team has steadily improved on the design with instrumentation and updates to the SCADA system, originally supplied by Instrument Control Systems (ICS).

One river pump station and two well pump stations deliver raw water directly into the plant. The waters mix in an influent chamber, and the flow then enters two 5.5 mgd softening basins (Infilco Degremont). Typi-cally, only one basin operates at a time, and when both operate, they work in parallel.

Water in the basins is fed with lime and soda ash, along with ferric sulfate as a coagulant and polymer for flocculation. Ammonia is also added in the softening stage for bromate control in the downstream ozo-nation process.

The WEDECO ozonation/recarbonation chamber (Xylem) has six cells fed with variable amounts of ozone and carbon dioxide, depending on raw water conditions. Residual ozone is sampled at various points in the chamber.

Before final filtration, fluoride is added, along with sodium hexameta-phosphate for heavy metal sequestration and corrosion control. The

plant’s four dual-media filter cells each hold two feet of anthracite coal atop 12 inches of sand. The filtered water goes to the clear well, where chlorine is fed to combine with ammonia and form chlora-mines for disinfectant residual. The water is then delivered to the res-ervoirs and water towers (7.9 mil-lion gallons total system storage).

Ozone does itHall notes that ozonation is

the key to odor and taste control. “We ozonate at very high pH [at times 11 or higher] so that we benefit from some advanced oxidation,” he says. “Ozone has been a really big improvement since it came online in 1995. It helps break down the organic material. Sometimes we feed CO2 with the ozone as the pH is dropping down close to that of the product water. That helps with taste and odor, too.”

But it wasn’t technology alone that conquered the variability of Red River water. The plant staff’s diligence had a lot to do with it. “Since we started this plant, we have probably doubled or tripled the amount of online instrumentation,” says Hall. “Our SCADA gives us a lot of infor-mation about water quality and what’s happening in the process, and we’re constantly trying to improve that.”

The system’s programmable logic controllers and other control hard-ware are from Allen-Bradley (Rockwell Automation), and the SCADA software is from IntelliSys Inc. Online instrumentation in the treatment plant and water system includes:

• Three total chlorineanalyzers fromWallace&Tiernan (SiemensWater Technologies Corp.)

• Monochloramine/ammonia analyzer, five pH monitors, and eightturbidimeters from Hach Company

• Two pH controllers (CO2 auto control), four ozone analyzers and two conductivity meters from Rosemount Analytical (Emerson Process Management)

• Organiconlineanalyzerfroms::canMeasuringSystemsBenchtop lab equipment includes a turbidimeter and spectrophotometer

from Hach Company, total organic carbon analyzer from OI Analytical, an IC chromatograph from Dionex, now sold as Thermo Scientific – Water Analysis, and an Orion pH meter from Thermo Scientific – Water Analysis.

The team tests raw water for hardness and alkalinity every four hours and tests the finished water every eight hours. The ozone analyzers test the water in the ozone contact chamber every 20 seconds. Ozone dosage is adjusted manually based on monitoring for ozone residual. “We have to adjust the ozone feed rate as water quality changes — on a good day, just a couple of times; on a bad day, once an hour or more,” says Haman.

Water from Moorhead, Minn., won the first two “Best in Glass”

taste competitions held by the state section of the American Water

Works Association at its annual conference in September in Duluth.

The event includes a vendor show where water samples from

communities that enter the competition are subjected to a taste test

and a popular vote among the attendees. The field is narrowed to

the top three vote-getters, which go to a second round of tasting by a

panel of three from Minnesota section members and a celebrity judge.

“In both 2009 and 2010, we won both the popular and the panel

vote,” says Troy Hall, Water Division manager for Moorhead Public Service.

“The official winner is the sample selected by the panel of judges.”

Another honor awaits: The plant is to be featured during 2012 on

an episode of the Discovery Channel’s “Dirty Jobs” program, showing

the process of cleaning the softening basins. Says Hall, “It has been

a fun year.”

The SCADA is programmed with the U.S. EPA ozone contact time (CT) requirements for disinfection. The ozone analyzers feed data directly into the SCADA, which calculates the actual CT value in real time. “In operations, we adjust the ozone, pH or whatever parameter is necessary to make sure the actual plant CT value is above the EPA requirements,” says Haman. “Once we meet the disinfection require-ment, 99 percent of the time the odor and taste issues are taken care of.”

As a teamThe staff’s success derives in part from the team atmosphere its lead-

ers try to create. “There’s a lot of overlap in the way we do things — a lot of cross-training,” notes Kris Knutson, water plant supervisor. “We don’t like to keep secrets between positions. We expect all our operators to be very familiar with the SCADA. As a supervisor, I try to involve the oper-ators so they can help me out with data analysis, maintenance tasks, or whatever happens to come up.”

Halbakken adds, “We communicate with each other. If one of us sees a problem, we alert the others. Everybody is always looking to keep the best product going out of the plant at all times. If that means someone has to be called at three in the morning to deal with a problem, everybody’s open to that. Everyone’s willing to help out.”

Notes Haman, “We try to work to each other’s strengths and shore up our weaknesses. For example, Nate is better at plumbing than I am, so I’ll give him plumbing jobs. In turn, he can give me data to analyze to find out when is the best time to order lime. We each have our little projects and our specialties.”

Hall cites SCADA work as an example of the team’s cooperation. “For the past decade, we have done all our SCADA work internally,” he says. “It’s not a perfect SCADA, but it has been built by people who really care about the end result. When we want to make a change in how a process works, we all work together.

“I’ve done some SCADA work in the office. Kris and Dan have done screen development for various purposes. It has evolved almost entirely in-house. We also select and install our own instrumentation.”

Problem solversTeamwork has helped the Moorhead staff resolve a variety of process

issues. Several years ago, pH variability was a constant challenge. Work-ing together, staff members made the correction by installing pH probes, making plumbing changes, and doing SCADA programming.

In another instance, rising non-carbonate hardness in the Red River was taking a toll on the soda ash feed pumps. A former operator located a peristaltic pump model (Watson-Marlow) that appeared better suited to the task. Operators, an instrument technician and electricians from the utility’s electrical side worked together to test and install the new pumps. “In a few months, we went from having to service the pumps every week to having almost no problems,” says Haman.

Another improvement involved installing a meter in the intake line to sample Red River water for conductivity as a way to predict total hard-ness in the river in real time. The team did the job, including data analy-sis and SCADA programming, entirely in-house, installing a used instrument purchased on the Internet for a few hundred dollars.

Future plans include installing instrumentation at the river pumping station, about three miles (two hours of in-pipe travel time) from the plant. “I’m excited about that,” says Haman. “We’ll be able to see changes in the water before it gets to the plant and so deal with them more effectively.”

Hall calls it a privilege to lead a staff with many and diverse talents. “The strengths of our people make it all work,” he says. “We try our best every day to use the strengths of the people we have.”

The results show up daily in the water glasses of Moorhead residents. wso

TasTesGreaT!Technology and teamwork help Moorhead Public Service deliver consistently high-quality water from a highly variable source in Minnesota’s Red River

STORY: Ted J. RulSehPHOTOGRAPHY: John BoRge

The Red River is best known for periodic floods that afflict North Dakota, most notably around Grand Forks. Much farther south, in Moorhead, Minn., the river is known for something else, though mainly to the staff at the water treatment plant.

“Up here, it’s not a big river,” says treatment plant operator Dan Haman. “Local events can have a large impact on it. A rain event can often wash interesting water into the river, especially if the weather has been dry for a while.”

Years ago, that led to complaints from customers about odor and bad taste in the water coming from the tap. That no longer happens. In 1995, Moorhead Public Service added ozonation to its treatment process, and it proved to be a reliable cure. In fact, for the past two years, Moorhead’s water has been voted the best tasting in the state in a competition held by the Minnesota section of the American Water Works Association.

Troy Hall, Water Division manager, credits the treatment technology, along with a talented operations team, with keeping the process on track. “When we look at the SCADA and see our water-quality trends, we want to see flatlines — everything just humming along,” says Hall. “Through teamwork, that’s what we’ve accomplished.”

Variable sourceWhat the Moorhead team calls the North Treatment Plant (10 mgd

capacity) was built in 1995. The old 6 mgd treatment plant is now rarely used: The staff operates it periodically just to make sure it remains func-tional and available for emergencies. When the plant operates, it treats well water only.

The new plant, with 10 full-time and two part-time staff members, was designed specifically to deal with variable source water in the Red River. The utility also draws well water from the Buffalo Aquifer, but the river provides about 85 percent of the source water on an annual basis.

“There’s a reason it’s called the Red River,” says Nate Halbakken, lead treatment plant operator. Which is to say it’s not what one would call

Water in the basins is fed with lime and soda ash, along with ferric sulfate as a coagulant and polymer for flocculation. Ammonia is also added in the softening stage for bromate control in the downstream ozo-nation process.

The WEDECO ozonation/recarbonation chamber (Xylem) has six cells fed with variable amounts of ozone and carbon dioxide, depending on raw water conditions. Residual ozone is sampled at various points in the chamber.

Before final filtration, fluoride is added, along with sodium hexameta-phosphate for heavy metal sequestration and corrosion control. The

plant’s four dual-media filter cells each hold two feet of anthracite coal atop 12 inches of sand. The filtered water goes to the clear well, where chlorine is fed to combine with ammonia and form chlora-mines for disinfectant residual. The water is then delivered to the res-ervoirs and water towers (7.9 mil-lion gallons total system storage).

ozone does itHall notes that ozonation is

the key to odor and taste control. “We ozonate at very high pH [at times 11 or higher] so that we benefit from some advanced oxidation,” he says. “Ozone has been a really big improvement since it came online in 1995. It helps break down the organic material. Sometimes we feed CO2 with the ozone as the pH is dropping down close to that of the product water. That helps with taste and odor, too.”

But it wasn’t technology alone that conquered the variability of Red River water. The plant staff’s diligence had a lot to do with it. “Since we started this plant, we have probably doubled or tripled the amount of online instrumentation,” says Hall. “Our SCADA gives us a lot of infor-mation about water quality and what’s happening in the process, and we’re constantly trying to improve that.”

The system’s programmable logic controllers and other control hard-ware are from Allen-Bradley (Rockwell Automation), and the SCADA software is from IntelliSys Inc. Online instrumentation in the treatment plant and water system includes:

• Three total chlorineanalyzers fromWallace&Tiernan (SiemensWater Technologies Corp.)

• Monochloramine/ammonia analyzer, five pH monitors, and eightturbidimeters from Hach Company

• Two pH controllers (CO2 auto control), four ozone analyzers and two conductivity meters from Rosemount Analytical (Emerson Process Management)

“We don’t like to keep secrets

The SCADA is programmed with the U.S. EPA ozone contact time (CT) requirements for disinfection. The ozone analyzers feed data directly into the SCADA, which calculates the actual CT value in real time. “In operations, we adjust the ozone, pH or whatever parameter is necessary to make sure the actual plant CT value is above the EPA requirements,” says Haman. “Once we meet the disinfection require-ment, 99 percent of the time the odor and taste issues are taken care of.”

As a teamThe staff’s success derives in part from the team atmosphere its lead-

ers try to create. “There’s a lot of overlap in the way we do things — a lot of cross-training,” notes Kris Knutson, water plant supervisor. “We don’t like to keep secrets between positions. We expect all our operators to be very familiar with the SCADA. As a supervisor, I try to involve the oper-ators so they can help me out with data analysis, maintenance tasks, or whatever happens to come up.”

Halbakken adds, “We communicate with each other. If one of us sees a problem, we alert the others. Everybody is always looking to keep the best product going out of the plant at all times. If that means someone has to be called at three in the morning to deal with a problem, everybody’s open to that. Everyone’s willing to help out.”

Notes Haman, “We try to work to each other’s strengths and shore up our weaknesses. For example, Nate is better at plumbing than I am, so I’ll give him plumbing jobs. In turn, he can give me data to analyze to find out when is the best time to order lime. We each have our little projects and our specialties.”




issues. Several years ago, pH variability was a constant challenge. Work-ing together, staff members made the correction by installing pH probes, making plumbing changes, and doing SCADA programming.


Another improvement involved installing a meter in the intake line to sample Red River water for conductivity as a way to predict total hard-ness in the river in real time. The team did the job, including data analy-sis and SCADA programming, entirely in-house, installing a used instrument purchased on the Internet for a few hundred dollars.


Hall calls it a privilege to lead a staff with many and diverse talents. “The strengths of our people make it all work,” he says. “We try our best every day to use the strengths of the people we have.”

The results show up daily in the water glasses of Moorhead residents. wso

TASTESGREAT!Technology and teamwork help Moorhead Public Service deliver consistently high-quality water from a highly variable source in Minnesota’s Red River

STORY: TED J. RULSEHPHOTOGRAPHY: JOHN BORGE

The Red River is best known for periodic floods that afflict North Dakota, most notably around Grand Forks. Much farther south, in Moorhead, Minn., the river is known for something else, though mainly to the staff at the water treatment plant.

“Up here, it’s not a big river,” says treatment plant operator Dan Haman. “Local events can have a large impact on it. A rain event can often wash interesting water into the river, especially if the weather has been dry for a while.”

Years ago, that led to complaints from customers about odor and bad taste in the water coming from the tap. That no longer happens. In 1995, Moorhead Public Service added ozonation to its treatment process, and it proved to be a reliable cure. In fact, for the past two years, Moorhead’s water has been voted the best tasting in the state in a competition held by the Minnesota section of the American Water Works Association.

Troy Hall, Water Division manager, credits the treatment technology, along with a talented operations team, with keeping the process on track. “When we look at the SCADA and see our water-quality trends, we want to see flatlines — everything just humming along,” says Hall. “Through teamwork, that’s what we’ve accomplished.”

Variable sourceWhat the Moorhead team calls the North Treatment Plant (10 mgd

capacity) was built in 1995. The old 6 mgd treatment plant is now rarely used: The staff operates it periodically just to make sure it remains func-tional and available for emergencies. When the plant operates, it treats well water only.

The new plant, with 10 full-time and two part-time staff members, was designed specifically to deal with variable source water in the Red River. The utility also draws well water from the Buffalo Aquifer, but the river provides about 85 percent of the source water on an annual basis.

“There’s a reason it’s called the Red River,” says Nate Halbakken, lead treatment plant operator. Which is to say it’s not what one would call

We were saved by the LAN, which makes the combined flow rates of the two wells readily available at the pumphouse. Within seconds of a well pump starting, the signal from the McCrometer flowmeters at the wells and a flow switch in the disinfection room allow the local Soft-I/O module to calculate how much sodium hypochlorite the metering pump(s) should inject into the pipe to the intermediate (contact) tank. A Hach CL-17 downstream of the intermediate tank tells us the free chlorine level as water is pumped to the main reservoir up the hill.

We set up the 30 hp lift pumps to follow certain priorities:1. Keep the tanks full regardless of electrical costs during high-fire-

danger times.2. Pump water when electrical rates are lowest, if practical.3. If one lift pump fails to start, or stops during its normal run, trig-

ger an alarm so that the other pump automatically starts and keeps the tanks full.

Alarms are also sent:• If the level of available sodium hypochlorite is getting low• If the chlorine analyzer shows a high or low free chlorine reading• If water levels are either higher or lower than a setpoint in any tank• If any pump fails to start or maintain flow• If the cloud servers lose contact with one of the sites

ResultsBy taking advantage of off-peak electricity, we reduced our electric

bill by about 25 percent. Some savings came from running the more effi-cient pump preferentially. Several times we detected system leaks very quickly, resulting in a tight system in which we billed about 99 percent of the water pumped.

More than once, we detected when an operator forgot to fill the sodium hypochlorite tank. We were able to see the outage graphically and refill

the drum before untreated water was pumped into the system. Since the cloud-based monitoring system has been active, we have had no out-of-water events.

I have become accustomed to picking up my smartphone or going to my desk and in a minute knowing that all is well on the system. Every event the SCADA system has recorded in the past year is stored in the cloud and is available, without taking up space on a local computer.

The bottom line is that the cloud-based SCADA system helps us anticipate problems rather than react, and thus our maintenance and repair costs have dropped dramatically. Looking at our energy savings and the reduction in emergency service calls, I can say we have made our small water district a better organization. It has certainly made my life easier!
