Undetected Water Leak Assistance

Undetected leakage is defined as a leakage within pipelines which are undetected. Both the fault and/or the water loss could not have been reasonably detected by visible inspection prior to Shoalhaven Water issuing an account.

Pipe Water Leak

Property owners may be eligible to apply for an undetected water leak rebate if they have received a larger than usual water usage component on their Water Account due to an undetected leak within the pipelines on their property. 

An undetected water leak rebate will only be issued once to a property while you are the owner.
