Sydney Water and delivery partner John Holland has taken a major step in the delivery of its $1.2 billion Upper South Creek Advanced Water Recycling Centre (AWRC). This forward step is in the laying of the first section of 40 kilometres of pipeline, to support waterway health.
The Treated Water pipeline will play a major role in waterway health and resilience. This follows one of the driest winters on recent record. It will carry high-quality treated water to the Nepean River at Wallacia to provide environmental flows.
This will help protect river ecosystems that continue to come under significant pressure from climatic changes and developments within the catchment. The high-quality treated water will help reduce weeds and the frequency of algal blooms.
Three sections of pipe have been laid in Cabramatta and Wallacia. It marks a critical milestone in the delivery of treated water and wastewater for the Western Sydney Growth Area.
The $300 million underground pipeline network will carry by-products from the wastewater resource recovery facility being built at Kemp’s Creek. It will be extended east to Lansdowne and west to Wallacia.
Two separate pipelines are currently being installed. One is a treated water line using a steel pipe. It will carry high-quality treated water to the Nepean River. The other is a brine pipeline, installed using PVC pipe. This pipe will transfer waste products to Sydney Water’s existing wastewater network at Lansdowne.
Sydney Water Delivery Manager Darren Wharton said the facility and associated pipelines are a significant step forward in the sustainable development of Sydney’s Western Parkland City.
“The Upper South Creek AWRC will supply wastewater services to 400,000 people in the rapidly growing Western Sydney Aerotropolis Growth Area,” said Mr Wharton. “This pipeline will ensure the facility will service parts of the Camden, Penrith and Liverpool LGAs. It will help cater for growth until 2056, enabling jobs and services throughout southwest Sydney.”
While John Holland’s Aidan O’Driscoll believes the pipeline and the facility will be a game-changer for South-west Sydney’s rapidly expanding population.
“John Holland is proud to be working with a group of experienced pipeline contractors to build more than 40 kilometres of pipeline. This project will produce high-quality treated water for Sydney’s rivers and waterways,” said O’Driscoll.
The pipeline network and Upper South Creek Advanced Water Recycling plant are due to be operational in 2026.
