Renewal works have resumed on the Coliban Main Channel, between Malmsbury and Bendigo, this month. The $4.6 million project aims improve the security and efficiency of the region’s water supply while protecting its environmental and heritage value. The three-year project involves the renewal of six concrete sections of channel, with a combined length of 2.7 kilometres. Coliban Water infrastructure delivery manager Corey Bourne said the channel was a critical piece of infrastructure meaning works had to be scheduled between May and October when the channel isn’t in use. “The Coliban Main Channel was constructed in the late 1860s to transfer water from Malmsbury to Bendigo and is still used to supply raw water to the Bendigo and Castlemaine Water Treatment Plants, as well as delivering water to our rural customers,” he said. “It is an open gravity channel, approximately 70 kilometres in length, and some of the sections we are renewing are around 60 to 70 years old.”
