Greater Parramatta and Olympic Peninsula water cycle management

Investing in sustainable water solutions

A new water resource recovery facility is planned for Greater Parramatta and Olympic Peninsula (GPOP), enabling future water reuse to sustainably service the Central City. The facility is to be located in the Camellia-Rosehill industrial precinct, the heart of the emerging GPOP growth corridor.


About this project

We're investing in more sustainable long-term water treatment and supply to support population and economic growth in the GPOP precinct.

GPOP is currently serviced by rainfall-dependent water supply from Warragamba Dam, with wastewater transferred by the Northern Suburbs Ocean Outfall Sewer (NSOOS) to the North Head Wastewater Resource Recovery Facility (WRRF) for treatment and release to the ocean. The NSOOS and North Head WRRF do not have sufficient capacity to service the projected growth for the GPOP area.

Over the next 30 years, the GPOP precinct will be home to an additional 250,000 people. To service this anticipated growth, we must invest in new infrastructure. Through the GPOP water cycle management project, we're taking the opportunity to shift from our reliance on coastal treatment and ocean discharge of wastewater. This work will help to manage water as a precious resource through more integrated water cycle management.

The project involves:

  • a new WRRF in Camellia-Rosehill
  • upgrades to the pumping station in Rosehill
  • a pipeline transferring wastewater from the pumping station in Rosehill to the new WRRF
  • a brine pipeline connecting the new WRRF to the NSOOS via the pumping station in Rosehill
  • a pipeline transferring advanced treated water from the new WRRF to the Parramatta River near Meadowbank Park.

This project is subject to an Environmental Impact Assessment. For more details on this process, visit the NSW Planning Portal to review the Scoping Report and Secretary's Environmental Assessment Requirements.

Benefits

Benefits for the community include:

  • efficient and cost-effective water services
  • high-quality recycled water for a range of potential reuses
  • an integrated approach to water supply and overall waterway health
  • enabling a circular economy through renewable energy and resource recovery solutions
  • supporting efforts to improve water quality in the Parramatta River.

Have your say 

We encourage stakeholders and the community to find out more and provide feedback on this project so we can deliver it in a way that meets expectations.
