Cobar Shire Council embarked on a program of water main renewals in response to the deteriorating condition of the existing town water pipeline.
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.

Scope of Works
Approximately 7km of the town pipeline consisted of cast iron pipes which repeatedly experienced a build-up of deposits that resulted in discolored 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
