Backflow Prevention Devices Backflow Prevention Devices

Council keeps a register of all backflow prevention devices. Find information on testing and registering backflow prevention devices.

Backflow prevention

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.

Where to start

Backflow prevention starts within a property boundary by isolating a possible contamination source from the town mains or storage tanks (rainwater tanks) from the tap or appliance.

Examples of potential source of contamination:

  • Fire Hose Reels (FHR)
  • Irrigation
  • Swimming pools
  • Ornamental ponds
  • Vehicle maintenance pits
  • Air conditioning towers
  • Vehicle/bin washing bays
  • Chemical injection areas

Examples of properties requiring backflow prevention:

Motels, hotels and unit complexes

Botanic gardens and caravan parks

Shops and restaurants

Dry cleaners and laundries

Medical and dental surgeries

​Car and plant washing facilities

Hospitals and funeral parlours

Sports club houses and schools

Day care centres and kindergartens

Pest control and water carrying vehicles

Vehicle repair workshops


Register of backflow prevention devices

Council is required to keep a register as per the following:

  • Standard Plumbing and Drainage Regulation 2003 Section 38 – Testable backflow prevention devices
  • 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.
  • The local government, or an entity authorised by the local government, must keep a register of the testable backflow prevention devices.
  • 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.
  • 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.
