WaterCorp Leak Allowance

Water Corp Leak Allowance

What is a leak allowance?

If you have a hidden leak and get it repaired by a licensed plumber or waterwise garden irrigator, you may be able to receive an allowance of up to 50% of the estimated water lost. The allowance, however, does not cover the cost for any repair work or services.

A leak allowance will only be considered after you have your plumbing or irrigation repairs completed to the required industry standards.

Leak allowance eligibility

We consider each application on a case-by-case basis. To be eligible for a leak allowance, you must meet the following conditions:

  • The leak must be undetectable (not visible).
  • Internal pipework needs to be repaired or verified by a currently licensed plumber or for any irrigation repairs, a WaterWise garden irrigator.
  • The licensed plumber must hold a current plumbing tradesperson’s licence under the direction and control of a Licensed Plumbing Contractor or contractor’s licence as issued by the Plumbers Licensing Board. For more information, visit commerce.wa.gov.au.
  • The plumbing or irrigation repairs must be compliant with government regulations.
  • You must be occupying and/or maintaining the property.


A leak allowance won’t be granted for leaks and/or bursts that occur on internal or external taps, internal appliances, fixtures or fittings, including dishwashers, hot water systems, toilet cisterns and valves.

Please note: A WaterWise irrigator is not allowed to repair leaks or install manual isolation or backflow prevention devices on your internal plumbing.
