You need to know the pressure in our water main.

This can help you design or certify one of the water connections for the building on the property.

Apply for a ‘Statement of available pressure and flow’ at Sydney Water Tap in.

We don't have any pipes for you to connect to.

Call us on 13 20 92 and apply to extend our water or wastewater system.

You want to change the level of your land and know this will impact the height of one of our wastewater structures.

Approvals: what you need to know

When to get approval

Why to get approval

What to do

You're excavating, demolishing or building on a property.

We need to ensure:

  • your proposed excavation, demolition or building works won't damage our pipes
  • we can still get to our pipes if we need to repair them.

Apply for a ‘Building plan approval’ at Sydney Water Tap in

If you're building close to or over our pipes, we'll refer you to a water servicing coordinator for detailed assessment.

You also need to apply for a Section 73 Certificate through a water servicing coordinator if you're building:

  • an additional dwelling on a property
  • a development, e.g. townhouses, villas, or commercial or industrial buildings.

 

You want to connect to, or disconnect from, our pipes.

We need to ensure the connection meets our requirements when you connect your property to our pipes.

We need to ensure any disconnection of services meets our conditions.

 

Apply at Sydney Water Tap in.

We approve most simple connections right away, but if you have a non-standard or large connection, we’ll ask you to provide more information and apply for approval.

If we approve your connection, we’ll send an approval letter or additional services agreement to you and the property owner.

If we approve your disconnection, we’ll send you an approval letter with conditions for disconnection.

You want to move or remove our pipes.

We need to ensure there are no problems moving or removing the pipes as they may need to provide services to other customers.

Apply for an ‘Adjustment/Deviation’ through a water servicing coordinator. The coordinator will advise you of the process and submit an application to us.

You've been offered the purchase of part of a public road.

We need to check:

  • if there are any pipes on the land
  • if any works are required to protect the pipes and maintain our access to them.

Request approval for a road closure through any water servicing coordinator.


BASIX compliance

You’ll also need to comply with a BASIX water target if you’re building a new home, doing a renovation that costs $50,000 or more, or installing a pool or spa of 40,000 litres or more.
