Backflow is the unintended reversal of flow of contaminated or non-drinking water into the drinking water distribution system.
Every water meter supplying water to a domestic or commercial property must have some form of Backflow Prevention Device (BPD) installed.
City of Coffs Harbour provides water meters with integral low hazard Backflow Prevention on services up to and including 25mm.
For medium and high hazard water connections or services above 25mm in size, it is the responsibility of the property owner to provide a suitable backflow prevention device.
Property owners are responsible for backflow prevention at their property in the following situations:
- medium or high hazard
- water service connections above 25mm
- below ground rainwater tanks, for more information see rainwater tanks
