Backflow Prevention

As required by the Texas Commission on Environmental Quality (TCEQ), the City of Marshall 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 City'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 City of Marshall continues to upgrade its program for Backflow Prevention and Cross Connection Control.  As required by the Texas Commission on Environmental Quality (TCEQ), the City continues to contact various businesses and residents with lawn sprinkling systems 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 checked on installation and annually thereafter by a state-licensed tester.
