A cross-connection is defined as any connection between a public water system and another water source through which it is possible to introduce contamination from the outside source to the public system. Some common examples include in-ground sprinkler systems, boiler type heating systems, fountains, livestock water troughs, wells, and directly connected hot tubs.
A backflow prevention device is required on the cross-connection. A test is required each year by a qualified tester to ensure no connection will contaminate the District’s water system. If you do not have a cross-connection to the District public water system, please notify the District in writing so our records can be updated.
It is the responsibility of the homeowner to contact a licensed testing service to schedule backflow prevention device testing. You must make sure the District receives a copy of the test report showing the device passes these tests
