UTILITY MANAGEMENT COMMITTEE (UMC) RECOMMENDATION
THAT Report No. WSC 118-2012, dated November 26,2012, from Len Stein, Director of Utility Operations, regarding JAMES Plant Monthly Report - November 2012, be received.
DISCUSSION
The plant effluent quality met all regulatory parameters for effluent discharge during the month of November 2012 and was well within the regulated limits. The key plant measurement parameters discussed below are defined and tabulated in appendices A-E. Al l results are forwa rded to MoE on a quarterly and yearly basis. All non-compliance parameters are listed in the reports to MoE.
InfluenVEffluent Data (Appendix A)
This shows the daily flows and influent and effluent quality on each day of the month. The fecal coliform test gives an indication that bacteria originating from the intestines of warm blooded an imals may be present in the wastewater.
All the required fecal coliform testing for the month of November 2012 were within acceptable limits. The limit for coliforms is 200 counts per 100 ml outside the initial dilution zone. The counts recorded are end of pipe prior to dilution from the Fraser River.
Biochemical Oxygen Demand (BOD) (Appendix B)
BOD is the rate at which oxygen in wastewater is used for the decomposition of organic matter in the waste water. High BOD rates reflect high organic content in the wastewater. Treatment plant processes reduce BOD levels before discharge to the environment.
The following chart compares monthly average BODs in mg/I.
The average BOD strength in the plant effluent for the three months listed was well below the regulated limit of 45 mg/!. BOD on the influent has increased due to industrial loading and increased concentration (not being diluted from the domestic sewage from Langley).
Total Suspended Solids (TSS) (Appendix C)
Total suspended solids are the total amount of solids that remain in suspension in the water. The higher the suspended solids concentration the harder the effluent is to disinfect and the higher the Biochemical oxygen demand will be.
The following chart compares monthly averages TSS in mg/!.
The above compares the average of TSS influent and TSS effluent strength over the same time period one year previous, for three consecutive months and is well below the regulated limit of 45 mg/!. For the month of November influent TSS are still higher than last year but are returning to a more normal level over the two prev,ious months.
All tests done for the month of November were well below the toxicity curve. In recent months Ammonia has increase over the same time period last year. Ph in the effluent has also increased slightly increasing towards the toxicity curve. This can be seen in appendix E.
Biosolids Utilization
2012 Biosolids Utilization Program (total to end of October. 2012) Highland Valley Mine 2,763 tonnes Biosolids to Val-E-Gro 2,729 tonnes Val-E-Gro sales 13,748 yards

DEFINITIONS
BOD (Biochemical Oxygen Demand) is defined as the
rate at which microorganisms use the oxygen in wastewater while stablizing decomposable organic matter under
aerobic conditions.
BOD Test is a procedure that measures the rate of oxygen use under controlled conditions of time and temperature.
Standard test conditions include dark incubation at 20 C
for a period of 5 days.
Suspended Solids (s.s.) are solids that either float on the surface and/or are suspended in water, wastewater, or other
liquids, and which are largely removable by laboratory
filtering.
Ammonia N (Ammonia Nitrogen) is tested as an indicator of
toxicity in the ptant effluent. General rule of thumb is that toxicity is being approached when the Ammonia N is in
the 20 - 25 mg/l range if the PH is above 7.S. At that range
or beyond, there is a good possibility of failing the required 96 hour LCSO Bioassay Test as outlined by Environment Canada
Fecal Coliform Test is an indicator for the presence of bacteria originating from the intestines of warm-blooded animals and their
presence may be indicative of the presence of disease producing
organisms that may be found with them. Zero or counts below the
maximum level of 200 cotonies/100 ml sample indicates that sufficient ch torine has been used for disinfection purposes.

WATER & SEWER COMMISSION (WSC) RECOMMENDATION
THAT Report No. WSC 122-2012, dated December 3, 2012, from Len Stein, Director of Utility Operations, regarding the Monthly Water Report - November 2012, be received.
DISCUSSION
Dickson Lake reservoir is at 638.4 meters (100%) of gravity and pumping. Cannell Lake reservoir is at 278.8 meters (100%) of gravity.
Attached are comparisons between November 2011 and 2012 flow percentages between Mission, Abbotsford and FVRD connection for the Cedar Mill. The flow percentage to Mission averaged 22.55% this month.
On Friday, November 30, 2012, above average chlorinated water was inadvertently allowed to enter into the potable water system at the water treatment plant. Although there was no health concerns, staff notified the health Department and the Mission Engineering department. Operations staff monitored different sites as the "slug" of chlorinated water moved through the system. Staff received no customer calls. An investigation is being conducted into how this happened.
SUMMARY
Staff are conduc' g a review to determine how a "slug" of above average chlorinated water entered the p e water system.

The Joint water supply system encountered ammonia spill incidents, one at Marshal and one at Townline Wells. The Townline well incident was first reported to Abbotsford Fire Rescue Service (AFRS) Saturday Nov. 10 at 0800 as they received a 911 call from a nearby resident who thought they smelled chlorine. When AFRS was on scene they called the operations Standby who responded to the site and found that the Ammonia Vat had become pressurized and overflowed with an ammonia/water solution. Staff proceeded to check other locations where ammonia is used and found that Marshall Wells had the same incident occur. The chorine/ammonia systems were installed and commissioned in 2012.
Ammonia is used in the chloramination process as an additive, so the chlorine has a longer life, thus preventing the installation of chlorine injection points in the distribution system. The ammonia used is a 29% solution and one (1) tote (approx. 50 gallons) is on site at each well location as very little ammonia is used in this process. The vat has the ability to hold 7 totes, so the ammonia spill was diluted at about a 7 to 1 ratio prior to spilling over and flowing to a rock pit drainage system.
Although Ammonia has a very pungent odour and is a severe respiratory tract irritant, the solution was contained within the well buildings and there was no public risk . A private company dealing with spills was contracted to dispose of the ammonia/water solution at an approximate cost of 8 to 9 thousand dollars.
Staff has taken all the wells offline and started an investigation into: How the system failed-which parts did not work properly Why they failed-was the right material used for the right application Was proper emergency procedure followed? Can costs be recovered from the designer/supplier/installer? What can we learn from this-did we do it right or can we improve

Dickson Lake Level - 2012 640 ,------------------------------------------------------------------------,
THAT Report No. WSC 117-2012, dated November 26,2012 from the Budget & Payroll Analyst (Abbotsford), regarding Financial Statements - October 2012, be received.
DISCUSSION
The attached statements present the operating and capital financial activities for the ten-month period ended October 31,2012 , along with projections to the end of the year.
Water Operating
Water Operating expenditures overall are projected to end the year slightly under budget.
Lease revenue for Water Operations is higher than planned due to an increase in the contract with Telus for their infrastructure on the Mt. Mary Ann Reservoir.
Water conservation is projected to end the year $100,000 over the original WSC approved budget due to the continued popularity of the toilet and washer rebate programs. The $100,000 expenditure increase was approved at the August WSC meeting and will be offset by savings in mai ntenance and utilities. The toilet and washer rebate programs each had an initial budget of $100,000 for 2012.
Spending in 2012 on the toilet and washer rebates has seen a consistent increase over prior year ($268,000 vs. $168,000). To date, $143,000 has been spent on toilet rebates and $125,000 on washer rebates. ICI audits and rebates have seen a decrease in expenditures ($30,000 vs. $101,000) which corresponds to a decreased 2012 budget for that area ($80,000 vs. $200,000).
Both maintenance and utilities are projected to end the year under budget which will offset the extra funding needed in water conservation . Maintenance and utility costs will continue to be monitored monthly and, should the need arise, a budget increase may be required at a later
24

date. Treatment and disinfection is projected to end the year $30,000 under budget; the soda ash facility is temporarily offline pending resolution of an equipment warral')ty issue. The facility is anticipated to resume operations by the end of December.
Sewer Operating
Sewer Operating expenditures are projected to end the year below budget.
Sewer revenue is projected to be $314,000 higher than planned. The variance relates to increased revenue from Industrial Extra Strength charges, and decreased revenue in the area of Biosolids Fabricated Soils.
Industrial Extra Strength charges are 25% ($204,000) higher than 2011 year-to-date (associated with higher BOD and TSS levels). The increase in Industrial Extra Strength charges for one company in particular accounts for 60% of the increase in revenue. The main impact of heightened BOD and TSS is on the capacity of the secondary part of the plant. Capital upgrades may be required sooner than planned if this trend continues. Industrial Extra Strength revenue is billed on a quarterly basis.
Biosolids fabricated soils revenue (Val-E-Gro) is lower than prior year due a wet spring that has resulted in slower than planned sales.
Hydro costs for the JAMES plant (accounted for under Wastewater Treatment Operations) continue to be higher than prior year; the Nitrification blower was not used for the majority of 2011 but is being used this year. Savings related to a vacant operator position are anticipated to more than offset the increased hydro costs. Maintenance costs are projected to end the year lower than planned as a millwright position was vacant for half of 2012 (savings of $45,000). Wastewater Treatment overall is projected to be under budget for the year.
Water Capital
Overall expenditures are currently within budget for the year. $0.7 million was spent in October, bringing the current year-to-date total to $11.2 million. Current projections indicate that $14.1 million of the $16.6 million budget is expected to be spent this year.
Sewer Capital
Overall expenditures are currently within budget for the year. $31 ,000 was spent in October, bringing the current year-to-date total to $2.5 million. Current projections indicate that $4.2 million of the $20.7 million budget is expected to be spent this year. Project delays due to pending grant funding accounts for the majority of the variance between projected capital spending and plan. Specifically with respect to the Stage VII upgrades at the JAMES plant, $9.8 million is projected to not be spent due to delays in grant funding. The funding for Stage VII has now been received and projects have gone out to tender. With respect to the JAMES Outfall Restoration of Pipe Cover, $2.6 million is currently projected as not being spent and will be rebudgeted in 2013 per WSC 96-2012. Current assessments indicate that this capital expenditure will not be required in 2012.
SUMMARY
MuniCipal contributions for operations are projected to end the year $43,000 below budget for the water system and $425,000 below budget for the JAMES plant. Capital expenditures are
25

projected to be below budget for the year.

REPORT
To: Abbotsford/Mission Water & Sewer Commission (WSC)
From: Len Stein, Director of Utility Operations
Date: October 10, 2012
Subject: The National Water and Wastewater Benchmarking Initiative
File: 5500-30/5600-30
Report No.: WSC 103-2012
WATER & SEWER COMMISSION (WSC) RECOMMENDATION
THAT Report No. WSC 103-2012, dated October 10, 2012, from Len Stein, Director of Utility Operations, regarding the National Water and Wastewater Benchmarking Initiative, be received.
BACKGROUND
The National Water and Wastewater Benchmarking Initiative (NWWBI) for the water and wastewater industry started in 1997. There are currently 43 municipalities representing 60% of Canada's population involved. AECOM Inc., a consulting engineering company, is coordinating the initiative.
DISCUSSION
The NWWBI compares performance measures from different utilities. The purpose of benchmarking is to record internal changes, compare results with other local governments in order to assess value for money spent, and learn ways to improve. For example, operations and maintenance (O&M) costs per kilometer of water main length are calculated, and then are plotted on a graph showing comparable utilities.
AECOM visits each utility to verify that the cost collection methods are consistent. This ensures that valid comparisons can be made, given that utilities are different ages, sizes, etc. As part of this process, utility staff attend a seminar to discuss the results and operational methods. This forum provides an opportunity for those with new ideas to share their thoughts and innovations with others.
The accompanying presentation shows a series of graphs for works performed in 2010, for both water and wastewater. The 2011 NWWBI analysis is currently underway. For reasons of confidentiality , names of other municipalities are not published . Utilities are plotted along the "X" axis in order of increasing size so that those of similar size are together.

ANALYSIS
Regional Water
The majority of water produced by the AMWSe is from surface sources, which have significantly lower costs than groundwater. Surface costs are kept low since gravity piping prevents the need for pumping water to the distribution system and the excellent raw water quality reduces the level of treatment required. Since staffing levels are low and major turnover can be expected in the next few years, a retirement transition plan should be put into place as soon as possible. Major upgrades to both surface and groundwater sources in 2010 easily met the recommended reinvestment targets.
Regional Wastewater
The JAMES pee has reached more than half of its expected life. It typically runs at 75% capacity, allowing for seasonal and daily fluctuations in flow, as well as some redundancy in case of failure. No non-conformances occurred in 2010. Staffing levels and O&M costs are typical for the size and type of plant. Although capital reinvestment levels have risen over the last number of years, they still did not meet the recommended target levels.
FINANCIAL IMPLICATIONS
N/A
COMMUNICATION PLAN
No communication plan is required.
SUMMARY
The benchmarking program was designed so that performance measurement data from different utilities could be compared. The results show that the wse compares very well with those in the survey group. The wse has a well maintained water and sewer system with a very low operating cost.

Subject: Industrial Extra Strength Rates Review
File: 5330-60
Report No.: WSC 119-2012
WATER & SEWER COMMISSION (WSC) RECOMMENDATIONS
1. THAT Report No. WSC 119-2012, dated November 30, 2012 from, Stella Chiu, Senior Drainage and Wastewater Engineer, regarding the Industrial Extra Strength Rates Review, be received; and
2. THAT staff develop an industrial extra strength rates review formula to recover capital upgrade costs, review permitting process and fines, consult with industry stakeholders and report back.
BACKGROUND
Currently industries pay extra strength user fees to discharge in the JAMES Plant sewerage area. These are mainly food processing industries in Abbotsford that produce organic wastes. The strength of the organic wastes is measured by Biochemical Oxygen Demand (BOD) and Total Suspended Solids (TSS). The extra strength user rate comprises three main components: (1) Operation and Maintenance (O&M) Costs of the JAMES Plant; (2) Asset Replacement Sinking Fund; and (3) Industrial Source Control Program Costs. The current extra strength rates are $0.42/kg of BOD and $0.47/kg of TSS. The revenue received from the extra strength customers is shared between Abbotsford and Mission based on historical average flow data .
While the extra strength user fee is a means to recover O&M and asset replacement cost from the extra strength industries, it does not account for the capital upgrades that are required at the JAMES Plant when these industries expand and increase their discharge. This report provides a review of this issue and recommendations of next steps.
DISCUSSION
In the past few years, the JAMES Plant has seen an increase in BOD and TSS loading coming to the Plant. An increase in loading was also observed from the industries. Historical flow and load to and from the Plant, digester gas produced at the Plant, biosolids production and industry loading data are summarized in Appendix A. A simplified process diagram that illustrates the data points is included in Appendix B. Note the 2012 projected data and data collected to date are also presented for reference.
56
Report No. WSC 119-2012 Page 2 of 6
The following observations were noted from data in Appendix A:
1) Comparing data in 2010 to 2011 (Table 1), flow to the Plant has decreased by about 10%. At the same time, BOD loading has increased by about 21%. However, this increase in BOD was not reflected in the biosolids production at the Plant during the same period (Table 3). The discrepancy may be due to the changes made to the influent channel to improve sampling methodology during 2010/2011.
2) Loading from the industries has gone up since 2010 (Table 6), and is partially causing the loading to the JAMES Plant to increase.
There are several issues relating to the increasing industrial loading to the JAMES Plant:
• The extra strength industries are mainly food processing industries that discharge organic loading such as BOD and TSS. Some of the industries operate all year around, while some operate seasonally. These industries can expand and change their process within a short period of time, causing large variations in the amount of BOD and TSS loading they discharge.
• Increased BOD and TSS loading to the JAMES Plant uses up secondary treatment capacity at the JAMES Plant seasonally or permanently depending on the industrial processes. This increases the need to move forward capital upgrades before they are planned.
• The current extra strength user fees only accounts for Operations and Maintenance and asset replacement costs. They do not account for growth or expansion from the industries.
• Historically the calculation of Development Cost Charges (DCC) is based on volume, instead of organic loading such as BOD and TSS. Organic loading from industries has a larger impact than flow to the JAMES Plant. For comparison, Joint Sewer DCC collected from the industries since 2010 estimated $56K, based on a total expansion of 1.96 ha. Flow generated from the 1.96 ha is equivalent to 63 people, or 19 homes. It is projected there is an increase of approximately 700 tonnes of BOD during the same period (Table 3). Assuming an average home generates 50 kg BOD/year, the increase in BOD is equivalent to 14,000 homes in Abbotsford, and has 740 times more impact than its flow.
Currently Source Control requires industries submit Wastewater Discharge Permit Applications on an annual basis. Through the permit application process, industries advise JAMES Plant staff their planned wastewater discharge volume and characteristics for the current year.
While the application provides valuable information of each industry, a funding mechanism needs to be in place to account for secondary treatment capacity and upgrades due to industrial loading at the JAMES Plant.
57
Report No. WSC 119-2012 Page 3 of 6
One option is to develop a three-tier system (on a kg/d basis), which is outlined as follows:
• Baseline: Review historical data of each industry and develop a baseline for each. The baseline would be the average of historical data. A nominal rate will be charged if industry discharges are less than or equal to its baseline. Each year the baseline will be adjusted taking into account the loading from previous year.
• Level 1: If the discharge is higher than the baseline but below Level 2, a premium rate will be charged.
• Level 2: If the discharge is higher than Level 2, the industry needs to resubmit its application . A higher rate may be applied, or pre-treatment at the facility may be required . Consideration may also be given to implement fines above the limit, e.g. $500/day.
This option will provide the JAMES Plant a mechanism to recover costs for secondary upgrades due to additonal discharge from industries, but at the same time provide a limit to prevent excessive industry discharges.
Regarding the high BOD and TSS coming into the JAMES Plant, it appears that some of the extra BOD and TSS is not accounted for from the extra strength industries. Staff will be working with Source Control to place composite samplers along the main trunk line to determine if any other customers are accounted for the extra BOD and TSS. Note part of the higher BOD and TSS could be accounted for from improved sampling at the JAMES Plant.
FINANCIAL PLAN IMPLICATIONS
With the proposed new Joint Sewer Capital Cost Sharing Formula, the growth-related capital costs for the JAMES Plant are proportioned based on flow and mass load. Industries in Abbotsford are currently included as part of Abbotsford 's load projection. It is therefore proposed that the extra strength revenue collected to cover capital upgrades be allocated to the city in which the revenue is collected, as this is consistent with the mechanism for sharing load-related costs.
COMMUNICATION PLAN
The proposed rate increase would need to be consulted with and communicated to the industry stakeholders, prior to implementation.
58
Report No. WSC 119-2012 Page 4 of 6
SUMMARY
The organic loading from industries to the JAMES Plant has increased in the past few years. The current extra strength user fees recover costs for Operation and Maintenance and asset replacements due to industrial loading, but do not collect for capital upgrades to address growth or expansion. A funding mechanism needs to be in place to account for secondary treatment capacity and upgrades due to industrial loading at the JAMES Plant. It is recommended that staff develop an industrial extra strength rates review formula to recover capital upgrade costs, review permitting proc d fines, consult with industry stakeholders and report back.

REPORT
To: Abbotsford/Mission Water & Sewer Commission (WSC)
From: Brent Schmitt, Water Planning Engineer
Date: November 28, 2012
Subject: Bevan Wells - 2012 Operations Summary
File: 5650-15
Report No.: WSC 120-2012
WATER & SEWER COMMISSION (WSC) RECOMMENDATION
THAT Report No. WSC 120-2012, dated November 28, 2012, from the Water Planning Engineer, regarding the Bevan Wells - 2012 Operations Summary, be received .
BACKGROUND
The Bevan Wells Environmental Assessment Certificate (Certificate) was issued in April 2011 . The Certificate required that a number of mitigation measures and commitments be fulfilled in order to operate the wells at full capacity. An amendment to the Certificate issued on August 8, 2012 allowed for the completion of the commitment to the Clearbrook Waterworks District. Shortly after the Certificate amendment was issued, the Bevan Wells production was increased.
DISCUSSION
Prior to issuance of the Certificate, the Bevan Wells production was not to exceed 6.5 MLD (75 lis). The allowable production limit with the Certificate is now 25 MLD, however this limit will not be reached unless the system hydraulics and overall demand require it. Usage of Bevan Wells in 2012 was maximized from August 13 through September 30. Daily flow rates during this period ranged from 6 to 19 MLD, with an average of 10 MLD. The highest output by an individual well was 6 MLD.
ANALYSIS
In order to evaluate the long term capacity of the wells , additional flow data and groundwater level monitoring will be conducted at higher production levels. While the wells were not utilized to the full design capacity of 25 MLD, staff will consider options for temporary system modifications in 2013 to allow for increased production from the wells.
An important consideration in determining the viability of the wells is the rate of drawdown of the wells during periods of increased production. In 2012, from June 1 to September 30, the groundwater level in the wells was drawn down by up to 2.2 m, with approximately 0.7 m recovery by the end of November (see Attachment A). The rate of drawdown was noticeably increased in mid-August during the period of peak production, but the groundwater level stabilized at lower production. Further monitoring of this trend will be conducted during the May
63
Report No. WSC 120-2012 Page 2 of 2
to September operational phase in 2013. Particu lar attention will be given to periods when peak production is encountered over a timeframe of several weeks. Excessive drawdown of the water levels in the wells could limit the pumping capacity.
Minor operational issues were encountered in 2012 . Modifications to the building ventilation system were required due to high temperatures in the control room when all four pumps were operational. Additionally, configuration of the level control transducer resulted in two of the pumps kicking-out frequently , thus not providing full production capacity. The transducers were modified and the issue was resolved.
When the Bevan Wells facility was first constructed the pumping capacity was limited to 6.5 MLD. Due to the reduced production capabilities, only a portion of the hypochlorite generation unit was constructed . The second hypochlorite generation cell is located on-site, but not yet installed. This unit is required in order to provide sufficient production of chlorine when the facil ity is operating at full design capacity for an extended period . Installation of the second cell is scheduled for 2013.
FINANCIAL IMPLICATIONS
There are no financial implications.
COMMUNICATIONS PLAN
There is no communications plan .
SUMMARY
Amendment of the Environmental Assessment Certificate for the Bevan Wells in August 2012 allowed for increased production from the wells in August and September 2012. Well production was previously limited to 6.5 MLD, but with increased pumping encountered a peak flow of 19 MLD in August. Groundwater levels dropped notably during the peak demand period, but stabilized at lower production . Operation of the wells at a higher capacity will again be conducted in 2013 in order to assess impacts on the groundwater level and the long term viability of the Bevan Wells .
