Cross connection and Backflow Protection Program
What are cross-connections?
A cross-connection is an interconnection or possible interconnection (permanently or temporarily) between a potable water supply (water safe for drinking) and a non-potable supply (not safe for human consumption).
Cross-connections can occur between a potable water supply and private irrigation systems, fire sprinkler systems, well systems, and any other pipe systems that receive the potable water supply.
What is Backflow?
Backflow is an unintended or unwanted reversal of water flow or other substances through a cross connection into a water system's distribution. Backflow can result in a potentially serious public health hazard.
Backflow Testing
The State of California requires backflow prevention assemblies be installed on all hazardous cross-connections to help keep our water supply safe. These assemblies must be tested and certified every year to ensure that they are working properly.
You as a home owner are responsible for hiring a licensed backflow tester to perform the annual test and certification of the backflow assembly(s) on your property.
Testing documents are sent out starting in October of the testing year and tests are due no later than December 15th.
