Undetected leaks

An undetected leak is where there is no visible sign of water loss, and both the fault and/or loss could not have been reasonably identified prior to us issuing you a bill.

It may have been an underground leak in your water service, under your home or hidden in a wall cavity and importantly not visible to you.

What is the Undetected Leak Rebate?

We offer an Undetected Leak Rebate to eligible customers as a gesture to our community, providing support above our contractual obligations. And as a goodwill gesture, we may give you an allowance of up to 50% of the increase in water usage if you meet the criteria.
