Client: NSW Public Works
Asset Owners: Cobar Shire Council
Cobar Shire Council embarked on a program of water main renewals in response to the deteriorating condition of the existing town water pipeline.
Approximately 7km of the town pipeline consisted of cast iron pipes which repeatedly experienced a build-up of deposits that resulted in discoloured water for some residents.
Not only were sections of pipeline prone to blockages and breaks, Council had a focus on improvements to bring the network up to a suitable standard and quality to provide the necessary flows for firefighting if required.
Killard Infrastructure was engaged to undertake the water main replacement project off the back of experience and quality water main service delivery at Dubbo, Goulburn and Cootamundra.
5-13t Excavators, Non-Destructive Digging truck, Vacuum Recycler truck, 2 x 2t Tippers, skid steer.
Pipe size & length

Mr. John Bevan
NSW Public Works
This project demonstrates our ability to successfully deliver regional water main replacement projects.
Innovative solutions included laser guided boring with pipejacking and concrete encasement of pipe, 3.4m beneath the railway line.
With Cobar in drought conditions, pipe disinfection water was recycled and used for the vacuum-jetter combination truck for dust suppression and jetting.
Unknown underground assets proved a challenge as many were unmarked on drawings and found only when construction commenced.
