About the Project

John Holland, Stantec and KBR are partnering with Sydney Water in an Alliance to deliver the North-West Treatment Hub – a brownfield treatment program that will commence with a $500 million upgrade of Rouse Hill and Riverstone wastewater treatment facilities.

The project will achieve circular economy outcomes, increasing recycled water production, improving the quality of wastewater byproducts for reuse, and leveraging innovative treatment technologies that reduce carbon footprint. Upgrades will support the treatment of a further 45 megalitres of wastewater each day, to cater for growing northwest communities.

The Project will deliver a new state-of-the-art biosolids facility at Riverstone, with new technology to improve the quality of wastewater byproducts.
