Backflow Prevention Strategy

Managing the Backflow Prevention Strategy

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

A backflow event can occur if a section of water main is isolated for maintenance work or there is a loss of pressure in a water main due to a broken pipe or similar occurrence.  Backflow may also occur if a pump system is connected to a customer’s internal water supply system.  Backflow from a non-potable supply has the potential contaminate Power and Water’s drinking water supply.

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

All properties developed after 1 July 2009 will be required to comply with the requirements of the Backflow Prevention Strategy, all existing properties identified as presenting a risk to the potable water supply must achieve compliance so as to comply to AS 3500.

These forms should be used as a guide only.  Power and Water will provide free of cost, books that contain 25 forms in triplicate, the white copy is to be forwarded to Power and Water, the yellow copy is for the property owner and the green is the book copy for the licensed plumber. Please contact Bill Bracken on 08 8995 5807 for these books.
