Keeping Your Water Safe Through Backflow Prevention

The District provides water that meets or exceeds all primary drinking water standards. If water from irrigation systems, pools, water softeners, or leaks, reverse direction and water flows back into the water system, it could potentially contaminate the drinking water supply and make it unsafe. Thus, it is important to prevent the backflow of water. 

Backflow and Cross Connections

The District’s water system is designed to deliver water in one direction – from the water supply source to homes and businesses. When backflow occurs, water from private plumbing systems may flow back into the District’s water system through “cross-connections” and potentially contaminate the drinking water supply.

A cross-connection is any connection between the District’s potable water system and a source of non-potable water or another substance. Cross-connections can be found on both commercial and residential properties. Without proper protection, these systems could allow contaminants to enter the public drinking water system during a backflow event.

The District is required by state and federal law to implement a cross-connection control program to protect the water system from backflow. Through this program, the District works closely with customers, contractors, and engineers to ensure that the necessary backflow prevention assemblies are properly installed, maintained, and tested.

Backflow Assembly Testing

Customers with backflow prevention assemblies are required to test their devices annually. State regulations require the use of certified testers. Provided below is a list of certified backflow assembly testers, program FAQs, and other related resources. Please contact the District’s Cross-Connection Specialist with questions or for additional information.
