The Texas Commission on Environmental Quality (TCEQ) requires every water supplier to develop and implement a comprehensive cross connection control program for the elimination of existing cross connections and prevention or protection from all future cross connections. As you may already know, the Rockett Special Utility District has elected to move forward with an eco-friendly online cross connection control (backflow preventer) tracking program. Backflow testers enter annual test data over the internet thereby saving tons of paper. Cross connections are sometimes protected by a valve called a backflow preventer. Backflow preventers are the property of the water customer and the responsibility lies with the customer for required annual testing and maintenance. The water customer must contract with a licensed tester to perform the required annual tests and any necessary repairs. Most plumbing contractors are now certified to test backflow preventers. Note that there are costs associated with testing, maintaining, and filing test results of backflow preventers. Backflow preventers may be found at any number of locations on your water systems. Typically, commercial & industrial customers will have backflow preventers just after the water meter and also on wet fire protection systems. They may also have lawn irrigation systems or other water connections throughout their facilities that require backflow protection. Residential backflow preventers may be found on lawn irrigation systems, wet fire protection systems, hot water heating (boiler) systems, swimming pool fills, water features, etc.  Backflow preventers may also be required if there is another water source on the site such as a well, pond, river, etc. Note that lawn sprinkler systems will be starting up soon. TCEQ and Plumbing Code require that your backflow preventer be tested annually and/or when the backflow preventer is re-installed every season. Please contact a local contractor to provide these services for you. The contractor hired by the utility to oversee the backflow program is Aqua Backflow. They specialize in cross connection control management. If you have or require backflow protection, you may be notified by Aqua Backflow for compliance (testing, repairs, installations, inspections, or surveys). They do not provide backflow testing, repairs, or installations. Aqua Backflowcan be reached toll-free at 866-777-2124 with any questions.
