What is backflow?

Backflow occurs when dirty water or other liquids flow in the opposite direction than intended, introducing contaminants and compromising the safety of the public drinking water supply.

This can be prevented by installing a backflow prevention device inline of the water supply. The appropriate type of backflow prevention device depends on the risk associated with the water use of a property.

Adequate backflow prevention is an important part of protecting public health and is required under:

  • The Building Act 2004
  • Health Act 1956
  • Health (Drinking Water) Amendment 2007


Why introduce a policy?

A Backflow Prevention Policy will:

  • Set out how the legislative requirements will be achieved
  • Provide guidance around how backflow risk should be assessed, and the appropriate device selected
  • Clarify device ownership, and assign responsibilities for maintenance, testing and renewal


Am I affected by the draft policy?

If the activities undertaken on your property require the use of chemicals or any other substance that could contaminate the water supply, then you should read and understand this policy.
