Cross Connection Control Program

Plumbing cross - connections are actual or potential connections between a potable and non-potable water supply.

Backflow preventers are located on water connections throughout the city, including most commercial and industrial establishments. systems, boiler systems, swimming pools and more.

Aqua Backflow has been hired to implement and oversee Evansville’s cross connection control program. If you have or require backflow protection, testing, repairs or installation, Aqua Backflow may be reached at (847) 742-2296 or toll-free at (866) 777-2124 with any questions.

The Indiana Department of Environmental Management (IDEM) requires municipal water suppliers to develop and implement a comprehensive cross connection control program for the elimination of existing cross connections and prevention or protection from all future cross connections.

Notice - Lawn irrigation systems will be starting up soon. Codes require that a backflow preventer be tested when the backflow preventer is re-installed or started up every season. All backflow preventers must be tested a minimum of once annually. You can read the NOTICE in its entirety here.
