Castle Hill Water Recycling Facility

Abergeldie has been awarded a major contract for upgrades to the Castle Hill Water Recycling Plant in Sydney’s north-west, ensuring a more efficient and integrated wastewater system to cater for growth in the area and will continue to keep waterways clean.

The contract – awarded by Sydney Water – is part of a larger project, known as the North-West Treatment Hub, which will link three treatment plants in the area, with the other two water recycling plants located at Rouse Hill and Riverstone.

At the heart of the project – which is due commence in 2023 – are several improvements focused on addressing the environmental impact of the plant on the local area, including reducing noise and odour levels at the site.

The scope of works to be undertaken include a new odour control facility, new pumps and pipes in the existing bioreactor, upgrades to switch rooms and transformers, a new ultraviolet disinfection system,and the demolition of redundant facilities.

Sydney Water Project Director, Bernard Clancy, said the plant is an important piece of infrastructure which 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.” Mr Clancy said.

Abergeldie Executive General Manager, Stephen Gasson, said the company is excited to be involved with the project.

“We’re thrilled to be delivering this important upgrade,” Mr Gasson said. 

“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.”
