Your water supplier. Newbury Park is part of the City of Thousand Oaks, and depending on the address it is served by California American Water or the City of Thousand Oaks. The supplier on your bill sends the annual notice. ### How often do backflow assemblies need to be tested? At least once a year, and again after installation or repair, by a certified Backflow Prevention Assembly Tester, under the State Water Board Cross-Connection Control Policy Handbook (section 3.3.3). Your water supplier mails the notice with the due date. ### What happens if my assembly fails? A failed assembly must be repaired or replaced and retested, generally within 30 days of the failure under the handbook (section 3.3.3), unless your supplier allows more time. We report the failure, coordinate the repair with a licensed contractor and retest the assembly. ### How much does a backflow test cost? It depends on the type and size of each assembly, how many you have, access, and any filing fee your supplier charges.
