Steps for first time developers

You need to follow some simple steps if you're developing your land, including:

  • building a new house
  • building residential apartments
  • building a factory
  • subdividing land.

As part of your council's development application process, you'll need to make sure you have adequate access to our services.

You need to apply for a Section 73 Compliance Certificate before you start building extra dwellings or subdividing your land.

You need to think about your development's water, wastewater and stormwater needs as you may need to build or construct something to meet our servicing requirements.

To help your planning, you can:

If you'd like to lodge a Feasibility application, you must engage a water servicing coordinator. They'll give you a copy of our letter that explains our charges, requirements and conditions for your proposed development.

When you're ready to start your development, you must apply for a Section 73 Compliance Certificate . This includes paying the application fee and doing any works listed in the Notice of Requirements.

Are you planning a large-scale land rezoning, new development or redevelopment project?
Call 13 20 92 for advice and ask for the Urban Growth - Growth Strategy team.


You need some type of consent or approval for your development from your local authority.

To find out what type of consent you need, visit your local council's website. They may have conditions for you to meet before they give consent. This will depend on what type of consent you need.

Once you have consent from your local authority, one of the conditions may be that you apply to us for a Section 73 Compliance Certificate. This certifies you have adequate access to water and wastewater services for your new development.

Read our Land development guide  for all detailed application steps.

If you're building, we'll need to approve your building plans. Your water servicing coordinator or your Sydney Water Developer Direct™ case manager can manage your approval for this.

Apply for your Section 73 Compliance Certificate

When you build or subdivide land, you normally require a Section 73 Compliance Certificate from us depending on the type of development you're planning.  

Find out more about what's involved in getting Section 73 Compliance Certificates.

At minimum, your development must have:

  • access to a suitable drinking water main to connect a metered property service 
  • a wastewater connection point (sewer junction) inside each property boundary.

Your local authority or council will ask for verification that you have a Section 73 Compliance Certificate. It ensures that:

  • your development or subdivision is served by our water, wastewater and stormwater system
  • your development or subdivision won't affect our water, wastewater or stormwater systems
  • you have paid any necessary contributions towards existing infrastructure (if applicable)

You can choose to apply for a certificate through:

  • a water servicing coordinator using our e-Developer system
  • Sydney Water Developer Direct™ online if you have a small-medium sized development.

Once you've paid your application fee, we'll assess your application. If you need to construct work to meet our requirements, we'll provide a Notice of Requirements outlining what you need to do.

You have to meet our requirements to get your Section 73 Compliance Certificate.

Your water servicing coordinator or Sydney Water Developer Direct™ case manager will give you a Notice of Requirements letter detailing what you need to do to get your certificate. This will be based on an assessment of your development and plans, and its impact on our systems. It will detail:

  • the construction works needed to make sure each lot has a frontage to a water main and a connection point to a wastewater main. Private water/wastewater service lines in easements or joint service arrangements are not acceptable
  • any costs and charges
  • any other requirements. This may include amplification or adjustment of our systems or pipes, or protecting our assets when you build over or next to them.

In general, most developments need a sewer connection point constructed and a water service for each new lot as a minimum.

If you need to build works, they must be constructed by one of our listed accredited  providers at your cost. 

The process is different depending on whether you lodged your application through a water servicing coordinator or Sydney Water Developer Direct™.

What you need to know about your application

Applications lodged with a water servicing coordinator

  • A coordinator must manage the design and construction work using listed providers. You can continue to use the coordinator who lodged your application, or change to another coordinator.
  • You and your providers must sign a Developer Works Deed.
  • You must sign a Complex Works Agreement for more complex works.


Applications lodged with Sydney Water Developer Direct™

  • Your case manager will have provided a design and quote for the construction works using listed providers. You can continue to use Sydney Water Developer Direct™ or change to a water servicing coordinator to manage the design and construction.
  • If you continue using Sydney Water Developer Direct™, you'll need to sign a Minor works contract and pay for the works up front.

What happens if your works impact neighbouring properties

If your works affects neighbouring properties not owned by you, you'll need to work with your coordinator or case manager to negotiate access.

You may need to pay compensation and/or look at ways to minimise any impacts. This can take quite a long time if many other property owners are affected.

Once the construction works are satisfactorily completed and inspected, we'll take them over as part of our system. We won't take over any of your private plumbing works.

When you've meet all the other requirements, we'll either issue your Section 73 Compliance Certificate to:

  • your coordinator (if you used a water servicing coordinator)
  • you directly (if you used Sydney Water Developer Direct™).

You can then give the certificate to your council to satisfy their development consent condition.

Building plan approval conditions

If your proposed building or development is within an impact zone, you may need to protect our pipes and assets to get your Section 73 Compliance Certificate and full building plan approval.

Sometimes these works can't be built or inspected until you start building, eg pouring concrete piers. In those cases, we can issue you with conditional building plan approval to take to your council. We'll give full building plan approval once the final protection works have been constructed and inspected.

Find out more about Section 73 Compliance Certificates.

You need our approval to connect to our water and wastewater systems. Find out what you need to know about connections and disconnections.
If you're developing, your  water servicing coordinator or Sydney Water Developer Direct™­ case manager can help you.

If you're connecting a business that produces trade wastewater, you must get our permission before you discharge to our wastewater system.
