We can also help if you have questions about a leaking water meter, wastewater faults and some stormwater faults.

Who looks after pipes and fittings?

Water pipes

You're responsible for maintaining all water pipes and fittings between our water main and the buildings/taps on your property.

We'll repair your water service under certain conditions
As a free service, if you tell us of a failure in your water system, we'll repair it between our water system and the meter -  up to one metre inside your property boundary. For units, this is the master strata property boundary.

You may also choose to hire a licenced plumber to do the work for you.

We may not be able to do any work if the service isn't easy to access, the connection isn't authorised or covered by the Customer Contract, or if it's a fire service.  You'll need to hire a licensed plumber to do this work.

What you need to know
If we repair a water service that's been  damaged or vandalised, we'll charge you to fix it. The cost will depend on the complexity of the work.

We may need to turn off the electricity supply to safely complete the repairs.

The property owner is responsible for restoring any private property affected by repair work, eg concrete, pavers, retaining walls, rockeries etc. 
Leak diagram

Please ensure there's plenty of clear space around your meter so we can easily access it for repairs and meter readings.

If you share a private joint water or wastewater pipe, you must maintain that pipe. How you split these costs is between you and whoever shares it with you.

Wastewater pipes

You're responsible for maintaining all wastewater pipes and fittings between your property and Sydney Water's wastewater system.

If you'd like to know where your wastewater pipes are, simply apply for a sewer service diagram at Sydney Water Tap inTM.
