All water supply systems intended for human consumption, food preparation, utensil washing or oral hygiene must be safeguarded from contact with contaminated water. This applies to water services connected to rainwater tanks, main water supply and/or alternative water supplies. A water supply should not be offensive in appearance, taste or odour.
Backflow prevention is the term used to prevent the reverse flow of water from a potentially polluted or contaminated source into drinking and bathing water supply systems. By installing a backflow prevention device this risk can be managed. There are a number of backflow prevention devices available to suit any particular situation.
Backflow Prevention Devices
A backflow prevention device prevents the reverse flow of potentially contaminated water into the reticulated water supply system.
Examples of potential source of contamination are but not limited to:
- Fire Hose Reels (FHR)
- Swimming pools
- Ornamental ponds
- Vehicle maintenance pits
- Air conditioning towers
- Vehicle/bin washing bays
- Chemical injection areas
Backflow Prevention Device Guidelines
Register of Backflow Prevention Devices
Council is required to keep a register of testable backflow prevention devices as per the Standard Plumbing and Drainage Regulation 2003
38 Testable backflow prevention devices
(1) A local government must implement and maintain a program for its local government area for the registration, maintenance and testing of testable backflow prevention devices installed in the area.
(2) The local government, or an entity authorised by the local government, must keep a register of the testable backflow prevention devices.
(3) An owner of an installed testable backflow prevention device must-
(a) register the device with the local government or entity; and
(b) at least once each year, have the device inspected or tested by a person who is licensed to do the work.
(4) A person who inspects or tests a testable backflow prevention device must, within 10 business days after inspecting or testing the device, give the local government written results of the inspection or test in the approved form.
