Backflow prevention devices

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

Backflow is the flow of water from a property back into the drinking water supply.

Council is committed to ensuring that our drinking water supply remains safe for everyone. A robust and effective backflow prevention system in place can help ensure water is safe to drink.

Contaminated water incidents can be serious. A backflow prevention device stops unwanted water flow entering our drinking water supply. This protects us from drinking or using contaminated water.

Failure to maintain your devices may result in compliance enforcement action.

There may be any number of contamination sources within a property. Backflow prevention provides a barrier, keeping contaminated water separate from the drinking water supply.

Sources of contamination can include:

  • irrigation systems
  • swimming pools
  • vehicle maintenance pits
  • ornamental ponds
  • air conditioning towers
  • vehicle/bin washing bays
  • chemical injection areas
  • fire hose reels (FHR)
  • commercial and manufacturing processes.

For more information refer to our backflow prevention devices fact sheet.
