Highton Basin Cover & Liner Replacement

Upgrade of the Highton Basin, a water supply asset serving more than 20,000 customers in Geelong and surrounding areas.

Scope

Keystone Civil delivered a critical infrastructure upgrade at the Highton Basin, a key water supply source for over 20,000 customers in Geelong and surrounding areas. The project focused on reducing water loss through evaporation and leakage by replacing the ageing synthetic liner and cover, originally installed decades ago.

Works included the careful removal and replacement of the basin’s liner and the installation of a new synthetic cover to improve water retention. A 3-barb chain wire security fence was also installed to enhance site security. Supporting infrastructure upgrades included new floats, weights, groundwater pumps, hatches, air vents, and hydrostatic sensors to optimise basin monitoring and functionality.

Keystone also reinstated groundwater pipework and electrical cables, ensuring the basin’s continued seamless operation. Strict safety and quality protocols were followed to minimise disruption to water supply throughout the project. This upgrade ensures long-term sustainability and functionality of the Highton Basin, reinforcing Keystone’s commitment to maintaining vital community infrastructure.

By conducting thorough investigations into the existing infrastructure, potential challenges were identified and addressed pre-emptively, allowing for the minimisation of additional costs associated with the electrical scope. Keystone Civil’s proactive approach enabled the timely raising of important issues to Barwon Water, resulting in the reduction of project delays and ensuring efficient project delivery within budgetary restraints.
