What to check for Fresno
Fresno irrigation content works because the city treats unavoidable cross-connections as cases where an approved backflow assembly becomes necessary.
- Due basis: 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.
- Who is affected: Fresno water customers with protected service connections, cross-connection hazards, or recycled-water systems that interact with the potable system.
