North West Hub Alliance

The North West Treatment Hub is a major Sydney Water infrastructure program designed to increase wastewater treatment capacity, improve network resilience and accommodate continued population growth in Sydney's north-west. Delivered by the North West Hub Alliance, the program involves significant upgrades to the Rouse Hill and Riverstone wastewater treatment facilities, including new treatment infrastructure and associated civil works.

Conlon Contracting continues to contribute to the North West Treatment Hub, with our civil crews undertaking earthworks, drainage and associated groundworks. Our involvement includes excavation, ground preparation and construction of internal site infrastructure within operational wastewater treatment facilities, working around existing Sydney Water assets while meeting project safety, quality and environmental requirements.
