Servicing growth & release areas

Houses being constructed next to road

We're planning new water and wastewater services for Sydney's south-west.

We're planning and building new water and wastewater infrastructure to enable development in the growth areas. This infrastructure is essential to allow development as outlined in the NSW Government’s A Plan for Growing Sydney.

NSW Planning and Environment is responsible for rezoning land and the sequence of land release in priority growth areas. They work in consultation with relevant local councils, NSW Government agencies and developers.

What we're doing

Sydney's North West is growing, with half a million people expected to live and work in the area by 2040. To ensure we're ready to meet future demand, we've started the $450 million Lower South Creek Treatment Program (LSCTP). 

This is one of the largest wastewater programs in the country, which includes:

  • increasing the size and capacity of our wastewater treatment plant in Riverstone
  • upgrading our water recycling plants at Quakers Hill and St Marys

Delivered by a joint venture between UGL Limited and WSP, the Lower South Creek Treatment Program introduces new leading edge wastewater technology that delivers significant sustainability benefits and has received the highest rating ever achieved for an Australian water infrastructure project from the Infrastructure Sustainability Council of Australia (ISCA).

The program is set to achieve a 42% reduction in whole of life greenhouse gas emissions which earned an Infrastructure Sustainability (IS) Design 'Excellent' rating of 69.7 points using innovative processes and technologies such as the transfer of sludge for consolidated biosolids processing and installation of mechanical primary sedimentation screens, which were Australian firsts.

The program's innovative wastewater technologies include:

  • leading edge wastewater technology from the Netherlands which will be used at Quakers Hill. It is energy efficient and has a significantly lower carbon footprint than the standard technology
  • thermal hydrolysis processing at St Marys that reduces the end product volume, improving dewatering and biogas production, and also reduces energy costs by producing more renewable electricity on-site

The Riverstone Waste Water Treatment Plant Upgrade became operational in January 2019, with capacity to serve 90,000 new residents. Work is now progressing at our Quakers Hill and St Marys sites. We expect the work to be completed by the end of 2021 weather permitting.

South West Growth Area

The South West Growth Area (SWGA) was established in 2005 to encourage a sustainable plan for Sydney's greenfield land development. The total area of the SWGA is 17,000 hectares that is split into 18 precincts. We define the SWGA as the area south of Elizabeth Drive to Oran Park.

We're building new drinking water and wastewater infrastructure to service about 200,000 new homes in Sydney's south west. The SWGA is covered by both Camden and Liverpool Local Government Areas.

  • Location - Austral, Leppington, Leppington North, Edmondson Park, Oran Park, Catherine Fields, Turner Road, Spring Farm
