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

Lower South Creek is a $300 million program, which will provide new and upgraded wastewater infrastructure to support an additional 500,000 people in Sydney’s west by 2040.

The program started in July 2016 and will be delivered by ADAPT – a joint venture between UGL Limited and WSP Parsons Brinckerhoff. Construction work began in early 2017. It includes:
  • upgrading wastewater treatment facilities at Riverstone Wastewater Treatment Plant and St Marys Water Recycling Plant
  • building a new biological nutrient removal plant at the Quakers Hill Water Recycling Plant.
