Backflow Prevention Policy

Backflow prevention devices stop contaminated liquids entering the water supply system.  

The Backflow Prevention Policy outlines Council's commitment to the protection of drinking water, and contains guidance for industrial, commercial and residential properties. 

Residential properties must have a testable backflow prevention device at the property boundary if they have:

  • an alternative water supply
  • a swimming pool
  • a spa
  • an irrigation system.
