If you have had a concealed leak on your property that has caused a sudden increase in your bill, you may be eligible for a once-off Concealed Leak Allowance.

The Concealed Leak Allowance:

  • refunds you 50% of the excess water usage charges that result from the leak (read below how this amount is calculated)
  • can only be claimed once per property, per ownership
  • comes in the form of a credit on your account
  • can be applied to a maximum of 2 billing quarters (based on the last two billing periods of the leak, including the one in which the leak was repaired).

If you have a shared meter (e.g. you’re in a duplex or apartment), your rebate will be calculated just like your bills: as a percentage of your overall usage.

The Concealed Leak Allowance does not cover water loss from: 

  • leaking taps, toilet cisterns, hot-water systems or other water appliances 
  • faulty plumbing or human error resulting in the filling of a rainwater tank 
  • property sprinkler or other irrigation systems 
  • swimming pools, spas, ponds and other outdoor water features, or their related fittings.

We examine your billing history to calculate your daily average usage in the last 12 months prior to the leak.

We then look at the bill/s that recorded the leak to calculate the amount of excess water usage.

The allowance is half (50%) of the excess water usage charges and all (100%) of the excess sewerage usage charges (if applicable). This is applied as a credit on your account.

FOR EXAMPLE

Normal water usage

$200

Now (with a concealed leak)

$600

$600 minus $200 =

$400

50% of $400 =

$200

Your allowance =

$200 plus excess
sewerage usage charges
(if applicable)

While our business customers are not eligible to receive the Concealed Leak Allowance, they may be able to apply for a sewerage usage allowance.

If a business has had a proven concealed leak, we recognise that this will lead to higher water usage charges and therefore higher sewerage usage charges on the bill. (Sewerage usage charges are calculated based on water consumption).  

Businesses in this situation can apply for a once-off adjustment to their bill to allow for this.
