Backflow is the unwanted flow of water from the internal water supply on a customer’s premises to Power and Water’s potable water supply system.

All properties developed after 1 July 2009 are required to comply with the Backflow Prevention Strategy and all existing properties identified as presenting a risk must achieve compliance.

Properties identified as presenting a risk to the safety and security of the potable water supply will be required to install the appropriate testable backflow prevention device.

Backflow from a non-potable supply has the potential contaminate the drinking water supply. Our customer brochure has more information on why backflow prevention is important.
