Water backflow

The installation of an appropriate backflow prevention containment device ensures the public water supply is protected from unintended cross connections and backflow.

Western Water’s Backflow Prevention Containment Policy applies to all property owners who have a connection to Western Water’s systems. It outlines the type of backflow prevention required for property connections in our service region.

Backflow prevention devices need to be maintained in accordance to plumbing regulations. A registered plumber should install and maintain the device.
