As required by the Texas Commission on Environmental Quality (TCEQ), Harris County Fresh Water Supply District 61 has an approved backflow/cross connection program in place to protect our drinking water supply.
If a water main breaks down the street, causing the water pressure to drop suddenly, it will create a backflow condition causing the hazardous liquid to be back-siphoned or sucked through the water hose into the District’s water main. Then after the repair has been made and as the water pressure is restored, this hazardous liquid could flow back into any customer’s drinking water system.
To protect our drinking water supply, the District continues to upgrade its program for Backflow Prevention and Cross Connection Control. As required by the Texas Commission on Environmental Quality (TCEQ), the District continues to contact various businesses and residents with backflow devices informing them to have their plumbing systems checked for proper backflow prevention assemblies and cross-connection control devices. All backflow prevention assemblies with test cocks must be tested upon installation and either annually or triennially thereafter by a state-licensed tester.
