Growth Servicing Plan

Our latest Growth Servicing Plan gives developers a high-level view of expected availability of where our water-related infrastructure will be available over the next 5-15 years. It includes maps showing infrastructure plans across major greenfield and infill areas. 

Western Parkland City

Our Growth Servicing Plan shows planning for water and wastewater services for developments like the Western Parkland City. 

Planning a cooler, greener future

Our long-term planning supports the NSW Government's vision of three sustainable, productive and liveable cities – the Western Parkland City, the Central River City and the Eastern Harbour City – and incorporates the coastline city in the Illawarra region.

By 2056, we’ll be providing water services to about eight million customers. We see our role going beyond our current high-quality water and wastewater services, with water playing a lead role in cooling and greening the city.

New maps and timelines

We update our Growth Servicing Plan each year with new insights and potential timing of new infrastructure. We’ve listened to your feedback to help shape the plan, which outlines:

  • a long-term planning outlook with maps of future water and wastewater
  • continued transparency of planning, processes and anticipated timelines
  • proposed trunk services in a selection of greenfield areas.
The plan aims to provide you with options for establishing the planning and infrastructure you need to support your development program.
We look forward to working with developers and local communities to get the right services delivered at the right time and create liveable, thriving and productive communities.

Funding developments

There are broadly two ways to fund new water infrastructure for growth areas:

We plan delivery of our services around the NSW Government’s land release program.

We must demonstrate that any decisions we make on funding infrastructure comply with the requirements set by the Independent Pricing
and Regulatory Tribunal (IPART). 

Before funding infrastructure, we must show that there’s demand for that infrastructure in the community, with a high certainty of delivery and timing.

Developments must be ready to connect to our infrastructure, soon after it’s constructed for it to be an efficient and economical investment. 

See the full Growth Servicing Plan for more details on how we decide when to progress planned infrastructure.

Developers can opt to independently fund infrastructure to accelerate planning and construction and can apply to the NSW Government to bring forward release of precincts for development. 

If the government approves the developer's proposal, we’ll work with the developer to establish a commercial agreement. This will outline financial arrangements and determine the best way to plan and deliver services.

See our Growth Servicing Plan for options on how to accelerate your development.

See our Funding infrastructure to service growth policy for more information about developer-funded infrastructure and conditions for reimbursement.

Publication of water and wastewater servicing information

According to the Sydney Water Operating Licence 2019-23, we must publish at least ten years of servicing information for major water and wastewater systems. To request access to the servicing information, please email
