Maintaining your service

Property owners are responsible for maintaining water and wastewater pipes and equipment up to where they connect to our systems. This includes:

  • private water and wastewater pipes and fixtures
  • backflow prevention devices
  • pumps used to boost water pressure in private water pipes
  • flow restriction devices on low pressure water services
  • wastewater pumps, tanks and other equipment (unless we have an additional services agreement with you that says we'll maintain it)
  • trade wastewater treatment equipment
  • fire services
  • extended private services and private water mains
  • joint private services and encroaching private services.


You must also keep our water meter free from damage and make sure we have access to read, maintain or replace it.

We own and maintain our:

  • water meters. We replace them periodically to ensure they stay accurate
  • own pipes. If you see a leak in our pipes, call 13 20 90.


As a courtesy, we may fix the section of your water pipes between our water main and your meter for free. We'll only fix pipes that are less than one metre inside the property boundary.

We won't do free repairs on:

  • extended private services 
  • unauthorised connections
  • fire services
  • inaccessible services
  • services where the damage was deliberate or negligent.

We'll maintain the junction, or the point where your wastewater pipe connects to our system. If your wastewater pipe has to drop steeply into our wastewater main, it's called a 'vertical'. We'll maintain any part of your vertical that's deeper than 2.5 metres from the surface.

We won't maintain any other part of your wastewater pipes, unless it's stated in an additional services agreement we have with you.

Joint services

You have a joint service if your water or wastewater pipe also serves other properties. Each owner who shares a joint private service is responsible for it. Joint services are more common in old parts of Sydney, such as terrace housing developments or very old industrial areas.  

If you think your property has a joint service, talk to your neighbours about engaging a private plumber to understand which neighbouring properties share your service. Once you understand this, you'll need to discuss:  

  • maintenance arrangements for the shared service, including access to private property
  • how you'll share maintenance and repair costs.


To disconnect the shared service from our water supply entirely, you need agreement in writing from all properties connected to the service.

To disconnect your property from the shared service, contact a licensed plumber. They'll arrange:

  •  the disconnection from the shared service
  •  a new connection to our network. 


Email connections@sydneywater.com.au if you need to discuss disconnections and reconnections.

Encroaching services 

You have an encroaching service if your private pipe crosses another property to connect to our mains.

Customers who benefit from encroaching private services are responsible for maintaining and repairing them. This includes the cost of any repair work – even when the pipe is in another person’s property.

If you have an encroaching service, talk to your neighbours to:

  • understand what properties your service crosses
  • negotiate reasonable access to their property to maintain and repair the service.


If you own a property that has someone else's private service pipes on it, talk to your neighbour. Make sure you both agree on reasonable access to maintain or repair pipes.

Extended private services 

Extended private services are more common in rural and bushland areas.

You might have an extended private service if:

  • your water meter is a long way from your property
  • access to your property is from a minor lane or road that doesn't have a water main along it
  • there are no hydrants along your road (indicating there may be no water main).


An extended private service may serve a single property or multiple properties.

If you have an extended private service, you and those who share the service are responsible for the costs of maintaining it.

If the pipe or meter is on public land, contact your council to find out if you need any permits before you start work to install, maintain or replace your extended private service. 

Leaks in extended, joint and encroaching services

If there's a leak, surcharge or blockage in a joint or encroaching wastewater service, the responsible owners must repair it as soon as possible to prevent health hazards and harm to the environment.

If an encroaching wastewater service is leaking in your property, contact the owner and ask them to fix it immediately. You may have to give them, or their contractors, access to your property to fix the problem.

Your local council may take action under the Protection of the Environment (Operations) Act if leaking wastewater is not stopped as soon as possible. 

If there's a leak in a joint or encroaching water service, responsible owners must repair it as soon as possible. Leaking services pose a threat to our network. If the leak is not fixed in a reasonable time, we'll disconnect your supply.

Managing disputes
Try to negotiate a solution to land access and cost sharing issues with your neighbour.

If negotiation isn't effective, NSW Community Justice Centres provides free mediation services to help people reach an agreement.

If you still can't reach agreement, you may be able to gain an order from your Local Court under the Access to Neighbouring Lands Act. You may wish to get your own legal advice about this.
