Client: Infrastructure Finance and Capital Works
Final Contract Value: $3.6M
Completion: June 2019 (on time)
The Molonglo 3 DN600 Water Supply Main project is located in The Pinnacle Nature Reserve between Weetangera and William Hovell Drive. This water main will be the main water supply for the new Molonglo developments (Whitlam etc.).
The 1.57km long water main includes a flow control valve and flow meter located in a large pit midway along the line. There are numerous air valves, scour valves, custom designed thrust blocks, access crossing, trench stops and bulkheads.
The works also involved connections to the existing DN600 Weetangera Reservoir outlet main which were planned meticulously with ICON Water to ensure the isolation of the reservoirs and reticulation network suited their forecast usage demand.
Additionally the water mains location within the Pinnacle Nature Reserve meant that stakeholder engagement and careful environmental management was a high priority on the project. The project corridor was narrow and closely controlled, and certain trees, roots and rocks were protected or relocated to ensure the project footprint was minimised as much as possible.
This project was awarded the 2020 ACT Master Builders and Asset Construction Hire Excellence Award – Civil Hydraulics category
