Over 25 km of mains will be replaced between South Hedland and the Yule Borefield to increase the amount of water that can be transferred into town.
A Water Corporation Spokesperson told Trenchless Australasia that the upgrade to the Yule pipeline involves around 60 m of pipe jacking, to cross the busy Great Northern Highway. This is being conducted by the corporation’s selected contractor, Ertech.
A second stage of the project will see the installation of three new bores and associated pipeworks at the Yule Borefield.
Work on the transfer main between the Yule Borefield and South Hedland began recently and upgrades to the borefield are expected to be complete by mid-2014.
The Yule Borefield will supply 10.5 billion litres of water to Hedland.
