Greater Parramatta and Olympic Peninsula Water Cycle Management

Sydney Water is investing in more sustainable and long-term water treatment and supply to support population and economic growth in the Greater Parramatta to Olympic Peninsula precinct (GPOP).

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. In order to service this anticipated growth, Sydney Water must invest in new infrastructure. Through the GPOP Water Cycle Management Project, we're taking the opportunity to shift away 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.

About the project

A new Water Resource Recovery Facility (WRRF) plant is planned for GPOP, enabling future water reuse to sustainably service the Central City. The facility is to be located in Camellia, in the heart of the emerging GPOP growth corridor.

The project involves:

• a new treatment plant in Camelia-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 Northern Suburbs Ocean Outfall Sewer via the pumping station in Rosehill

• a pipeline transferring advanced treated water from the new WRRF to the Parramatta River near Meadowbank Park
