Why do I need to get my backflow device checked if I have a pool or sprinkler system? The answer is simple, it is the law. TCEQ requires backflow devices on all residential meters that have a pool with an automatic fill or a sprinkler system to prevent harmful chemicals and other dangerous substances from backflowing into the main line and contaminating the entire water system. It is the responsibility of the home owner to let us know if they have sprinkler system or pool or if plan to put one in. In fact, it is all right there in the service agreement. We have a responsibility to make sure that as we become aware of a pool or sprinkler system to check these devices to protect our system. Keep in mind, this not just an SS Water System procedure. TCEQ enforces this for all public water systems, this means cities have to comply as well. Recently, TCEQ has mandated that public water systems will have a comprehensive list of all connections that have a need to be back flow tested and have them tested yearly. This is for your protection and the protection of our entire system. We have been working hard on creating our list, so any help you can provide is greatly appreciated. Our water system is precious and is the most vulnerable for any type of mass contamination of the public. It is our goal to provide every member with safe potable water and by enforcing and following the standards set forth when it comes to backflow prevention, we are achieving that goal.
