West Dapto Urban Release Area

New water and wastewater infrastructure will be needed for Avondale, Calderwood, Calderwood Valley, Cleveland, Huntley, Kembla Grange, Sheaffes/Wongawilli, Tallawarra Lands, Tullimbar Village, West Horsley and Yallah/Marshall Mount.

The project will be completed in stages between 2014 and 2048.

New services are needed for about 30,000 homes in the Illawarra.

About the West Dapto Urban Release Area

The West Dapto Urban Release Area and Adjacent Growth Areas are expected to accommodate about 30,000 homes and nearly 500 hectares of non-residential development up to 2048.

In 2013, we developed a proposal to provide water and wastewater services in stages until 2048 to meet urban growth needs. We worked closely with many stakeholders while developing our proposal, including:

  • the Department of Planning and Environment
  • local councils
  • relevant state agencies
  • the Illawarra Urban Development Committee
  • the local community.

We then prepared an Environmental Assessment (EA) to support our application to the Department of Planning and Environment, under Part 3A of the Environmental Planning and Assessment Act 1979. We aim to avoid environmentally sensitive areas and commit to a range of measures to minimise environmental impacts. 

Project area

Since the project started, the forecast demand for infrastructure and the approval framework has changed significantly.

In January 2016, the Department of Planning and Environment approved a modification of the original approval. The modified project area only includes infrastructure in Kembla Grange, Sheaffes/Wongawilli and West Horsley (see map below).

Additional environmental assessments will be completed in line with forecast demands for the remaining areas of Avondale, Calderwood, Calderwood Valley, Cleveland, Huntley, Tallawarra Lands, Tullimbar Village and Yallah/Marshall Mount.

We're planning to deliver infrastructure to service five development stages: 

We'll continue to consult with affected stakeholders throughout the planning, design and construction process. This includes government agencies, landowners, developers and the wider community.

How do we plan for the delivery of services in this area?

We work with a number of stakeholders to coordinate the delivery of our infrastructure in stages, as individual precincts and growth areas are released and rezoned.

They include: 
  • the Department of Planning and Environment
  • the local electricity provider and other utilities
  • Roads and Maritime Services
  • local councils
  • developers
  • landowners.

We have a Growth Servicing Plan (GSP) that outlines the planning and delivery timetable for water and wastewater infrastructure to service urban growth over five years.

The plan demonstrates how we're meeting the NSW Government’s development timetable. The Department of Planning and Environment prepares the plan based on the Metropolitan, Employment Land and Illawarra Urban Development Programs.

Why aren't we ready to build all the infrastructure before the precinct or growth area is rezoned?

The Sydney Water Act states we must operate as a successful business. For urban growth, we target and prioritise our capital expenditure to service areas that are likely to develop in the short term and provide a return on our capital investment.

To achieve this, we stage our service delivery in coordination with other government agencies. We take into account the Department of Planning and Environment’s development programs, which incorporate rezoning and land release sequencing.

The water and wastewater infrastructure required to service an area is based on demand, development timing and staging. Until precincts and areas are rezoned, we can't predict the demand for services in that area.

Precincts and growth areas in the West Dapto Urban Release Area and Adjacent Growth Areas are large, with many new homes planned. Because of this, it can take years for the entire precinct to develop completely. If we built all the infrastructure required for the long term, many assets would be under-used for many years.

Once an area or precinct has been rezoned, developers need to prepare and lodge development applications for the sub-division and development of their properties. This process can take up to two years. This means there's usually a two-year gap between when a precinct is rezoned and when the first new home is built in the precinct and service connections are required.

Will you be able to connect directly to the water and wastewater trunk pipelines that we build?

No. We usually build the major trunk pipelines that customers can't connect directly into.

Once our trunk infrastructure has been built, smaller pipes will need to be installed to allow properties to connect to our system. Developers will install these smaller pipelines, ( reticulation and lead- in pipes), to service individual properties, as customers can't connect directly into trunk pipelines.

How can you connect into the water and wastewater service?

If water and wastewater services are available in your area, and you'd like to connect to the system or sub-divide and develop your land, you need to get a Section 73 certificate. Your application for a Section 73 certificate needs to be lodged by a Water Servicing Coordinator through our e-developer process.

Learn more information about Section 73 certificates and Water Servicing Coordinators.

Why don't we build all the trunk infrastructure and smaller reticulation pipes?

A considerable amount of infrastructure is required to service the entire area. There's uncertainty about where and when other infrastructure such as roads, gas, phone and power will be located until:
  • a precinct or growth area is rezoned
  • precinct plans have been developed
  • subdivision road layouts are finalised.
Smaller pipelines in these precincts and growth areas are usually laid in road reserves. It's often more efficient and effective to have developers lay the infrastructure as they're building the roads for a new housing development.

Who will build the rest of the pipelines?

Developers will build the rest of the pipelines as they're building new homes and roads in the area.

Who will have to connect to our water and wastewater system if it becomes available?

You won't have to connect to our system if you choose to continue living in your current home.

If you wish to build a new home, sub-divide or redevelop your land, you need to speak to your local council about any conditions imposed on local developments.

How much will it cost to connect to our water and wastewater network?

There is no set fee to connect to our network.

When we receive a Section 73 application, we issue a Notice of Requirements detailing what needs to be built to service new developments. The requirements are influenced by the size and nature of the development and where the development is in relation to our trunk network. Meeting these requirements is a large part of the cost required to connect to our network.

Charges that may be incurred include:
  • contract administration fees
  • fees for checking building plans (there may be requirements for building over or next to the wastewater pipes)
  • plumbing and drainage inspection and connection fees, eg water main drilling costs
  • Sydney Water trade waste charges for industrial and commercial developments
  • fees for approving large drinking water connections.
