Sydney Water senior project manager James Paton said the microtunnelling works will dig 10 metres underground and 700 metres along.
“This project will provide drinking water and wastewater services to approximately 17,000 homes by mid-next year,” Paton said.
“Microtunnelling is a trenchless technique which utilises a remotely controlled boring machine to excavate a tunnel and concurrently install pipes.”
Microtunelling will be used for deep sections of pipe and to minimise surface disruption and assist in the end goal of providing critical water infrastructure to the city’s future housing.
“The use of microtunnelling for the project ensures precise alignment and grade control,” Paton said.
“Confluence, through Rob Carr, have utilised laser guidance systems and temporary works design to ensure the tunnel meets specifications and existing assets remain undisturbed.”
Paton noted the importance of investing in water infrastructure for Sydney’s future growth.
“As Sydney looks ahead to an expanding future, this strategic investment in water infrastructure exemplifies a commitment to sustainable growth and community wellbeing,” he said, “laying the foundation for generations to thrive in North West Sydney.”
