Major upgrade planned for Castle Hill Water Recycling Plant

Sydney Water has been awarded a major contract to upgrade the Castle Hill Water Recycling Plant in Sydney’s North-West. The investment will aim to ensure a more efficient and integrated wastewater system to cater for growth in the area and help keep waterways clean.

The contract for the site upgrade has been awarded to Abergeldie and is part of the North-West Treatment Hub, a larger project that will link the Castle Hill, Rouse Hill and Riverstone plants with each other.

Several improvements addressing the environmental impact of the plant on the local area are at the heart of the project, including the reduction of noise and odour levels at the site. The project will see the installation of a new odour control facility, new pumps and pipes in the existing bioreactor, upgrades to switch rooms and transformers, an ultraviolet disinfection system and the demolition of redundant facilities.

Bernard Clancy, Sydney Water Project Director, said the plant is an important piece of infrastructure that will leave a positive legacy.

“The upgrade of the Castle Hill plant is all about building a more sustainable system that will not only continue to provide a reliable wastewater service, but also contribute to reducing our energy and carbon footprint through renewable energy,” Clancy said.

Stephen Gasson, Abergeldie Executive General Manager, expressed his excitement to be involved in the project.

“We’re thrilled to be delivering this important upgrade. Our selection for this project exemplifies our close working relationship with Sydney Water, our cultural alignment and our shared vision for the sustainable delivery of this complex project,” he said.

Upgrades to the Castle Hill Water Recycling Plant will commence in 2023.
