The Bexar Metropolitan Development Corporation (BMDC) contracted United Water for the fi rst design, build and operation (DBO) of an ultrafi ltration water treatment plant in the United States in San Antonio, Texas. The BMDC is an industrial development corpo-ration formed by the Bexar Metropolitan Water District, which provides water to about 150,000 residents in the San Antonio area.
SCOPE OF SERVICES
The new high-tech water treatment plant is part of a 10-year $30 million agreement between United Water and the BMDC. Under the terms of the contract, United Water is responsible for all aspects of designing, build-ing, managing and operating the new surface water structures including the ultrafi ltration water treatment facility, raw water intake, raw water pipeline and pump-ing station. The BMDC owns all the facilities, provided fi nancing for the construction project and constructed a fi ve-mile pipeline to bring safe drinking water to key points on the west side of San Antonio.
The innovative ultrafi ltration process provides an absolute barrier to unwanted particles in fi nished water through removal of solids, organics and pathogens.
The new ultrafi ltration plant treats water from the medi-na River, making it the fi rst facility in the San Antonio
area to treat surface water. This represents a major step in reducing the water demand on the Edwards Aquifer.
United Water recently ran pilot testing that resulted in the rated capacity of the facility increasing to 14.5 MGD in summer months and to 10.8 MGD in winter months, compared to the plant's designed capacity of 9 MGD. United Water achieved this without additional capital investment.

Happy New Year! Januaryʼs meeting will take place on the eighth at the Bexar Met Plant southwest of town. The map, and directions to the site are posted on the IN THE NEWS section at ABPA-SA.com. We are all in-volved in a program, which seeks to prevent damage to their product. For those of you who have to ex-plain the merits and need for the backfl ow program and/or its requirements, a visit to this facility can add weight to your comments.You will be able to say that you have been there,that you have seen the expensive equipment and ef-fort which gets used every day to provide safe drink-ing water to the community. Wouldnʼt it be a shame to let some neglected device or connection ruin the investment made at that plant, and possibly add injury to insult in the process? Come out! Ron is bringing food, Troy and buddies are bringing grills, and good or bad, the weather will certainly be there!

ACCOMPLISHMENTS
Decreased Cost• By utilizing the IDC and a DBO procurement methodology, the total project cost was reduced to under $1.25
per 1000 gallons produced, an estimated 30% reduction over a traditional design-bid-build approach.• Extensive pilot testing performed during the design phase of this project signifi cantly reduced equipment costs
from the original manufacturer estimates.Innovative Technology• United Water brings the ultrafi ltration water treatment technology of "Crystal," developed by parent Suez, to
the San Antonio community.• To extend the life of the membranes, the design of the plant includes a Super Pulsator clarifi er to pretreat the
raw water prior to fi ltration. This results in greater fi ltration effi ciency.

Safety Tip of the MonthThe water utility industry has continually ranked
back injuries, due to strains and sprains, as its most common injury, and National Safety Council statistics show that oc-cupational back injuries “account for at least 20 percent of all occupational injury cases.” This means that approximately 400,000 disabling back injuries occur at work each year.
Special Note: 25 percent of all occupational back injuries occurred to both men and women who work in the offi ce. Bending over to retrieve items from bottom fi le cabinet drawers, reaching over desktops, stooping to pick up items from the fl oor.
AWWA statistics show that approximately 18 percent of reported disabling injuries resulted in back injuries. Ob-viously, prevention of back injuries should be an issue of unanimous concern.
What can we do about preventing back injury? Cer-tainly one of the most practical things we can do is to be in good physical shape through proper diet, regular exercise, and adequate rest. Another thing we can do is to realize that there are certain objects, due to size, weight or bulkiness that one should not lift alone. Too often, we say to ourselves, “Heck, I can lift this, No Problem! ” We donʼt acknowledge the aging process of the body as readily as that of our aging eyes. Donʼt assume that because you could lift that load for the last few years, you will always have that ability!
Oddly, the weight of the load doesnʼt have to be ex-treme to bring about an injury. If it has an irregular shape, that requires you to twist or bend in an awkward position to lift, the back becomes much more susceptible to injury. Do you realize that if you bend from the waist to pick up a 50-pound object that in reality you are applying 10 times the weight to your back? You must lift properly. What is the proper technique? The proper technique can be stated very simply: “ Bend Your Knees.”
Thatʼs right. If you will remember these three short words, you will have accomplished what we are trying to instruct you to do. Obviously, there are more proper lifting techniques such as grip, being able to see over the object that you lift, wearing the proper personal protective equip-ment (i.e., back support belt, gloves, and safety shoes), and realizing that fi ngers can get caught in “pinch points” if you arenʼt careful. But when it comes to basics, remember those three simple words---Bend Your Knees.
Back injury is not just an occupational injury. We can also injure our backs working at home, while playing sports, on vacation and so on. Keep in mind the lessons we learn from work when we leave work. No one is exempt from a back injury. The pain is the same no matter if your injury occurred at home, at work, or a play. Safe Behavior and At-Risk-Behavior applies no matter where we are. Play it safe.
Experts estimate that approximately one third of all back injuries are result of excessive mechanical stress on the back and spinal column. In our daily routine we lift, carry, hold, and push objects in many sizes, weights, and shapes, placing stress on the structure of the back. We incorrectly lift because of lack of help or poor initiative to do it right.
While trying to become more productive and save time on the job or at home, we often attempt to handle more than we are physically able. In the short term this appears to be of no harm, but we are setting the stage for a debilitating injury. Back injuries are caused by repeated stress and strain throughout one s̓ lifetime. The stress and strain creates many little “micro fractures” that scar joints and result in loss of elasticity and inability to bend.
A back injury is a direct result of poor lifting tech-niques. Your back consists of a series of muscles and bones, and contains your spinal chord and nerves, which pass signals from your brain to the many parts of your body. A pinched nerve due to a back injury is very painful. The spinal chord, an S-shaped bone structure with stacked bones and cushions (discs), is much like a jelly donut. As a personʼs back is injured, some of the “jelly” is removed. In time, as most of the jelly has exited, the bones rest directly on each other and grind away their substance. Then the pain increases.
Use Your Brain and Prevent a Strain
Use a fl at straight clear route (even if it is longer)
Move objects that you might trip over.
Clear the loading and unloading area.
Bend at your knees and keep your back vertical.
Grip with your hands, not your fi ngers.
Let your legs do the lifting work.
Lift your head and shoulders fi rst.
Do not twist as you lift or carry.
Back safety is not a question of strength; it is one of sensibil-ity and longevity. To protect our backs, we need to do it right all the time. So itʼs up to you to take care of your back.
Remember, you need your back pain free, at home, at work and at play.
