Wentworth Raw Water Mains Renewal

Wentworth Raw Water Mains Renewal
PROJECT OVERVIEW

The project involved the Design and Construct renewal of Wentworth's sole raw water supply main to the Wentworth Water Treatment Plant.

Scope

The project involved the Design and Construct renewal of Wentworth’s sole raw water supply main to the Wentworth Water Treatment Plant. The existing main beneath Tuckers Creek had experienced repeated failures, posing a critical risk to township water security and the local hospital.

Works included the installation of a 184m DN400 PN20 PE pipeline beneath Tuckers Creek via horizontal directional drilling (HDD) to a depth of approximately 12.5m, along with DN400 and DN300 pipeline connections through William Street and Armstrong Avenue. Additional trenchless works were undertaken to minimise disruption to driveways, services and established vegetation.

The project required complex live tie-ins under tight shutdown windows, installation of valves and fittings, swabbing, pressure testing, commissioning, and full reinstatement. Delivered within environmentally and culturally sensitive areas, the works incorporated extended bore alignment to avoid protected vegetation zones, strict environmental controls, and proactive community engagement. The project was completed 11 days ahead of program with zero service interruptions.

PROJECT SUMMARY

Built on experience. Ready for what’s next.

This project demonstrates Keystone Civil's capability in water & sewer, combining practical construction methodology with coordinated delivery in a complex operating environment.
