The city term helps discovery. The governing utility still decides the rule, submission method, tester route, and follow-up order.
Fresno annual backflow testing
Annually once the assembly is in the city program Fresno says annual tests of backflow devices are mandated to verify they work correctly. The Water Division manages more than 9,700 backflow devices across the city and coordinates planning, installation, and maintenance through the Cross Connection Control program.

Why Fresno maps to City of Fresno Water Division Cross Connection and Backflow
City search demand maps directly to Fresno Water Division and the governing cross-connection program.
- Fresno water customers with protected service connections, cross-connection hazards, or recycled-water systems that interact with the potable system.
- Fresno frames cross-connection control as a city program with records of locations, tests, and repairs. Recycled-water customers must notify the city at least 48 hours before a cross-connection test supervised by the city.
