The mains were originally located under the road bridge, and for the past 14 months temporary pipes have been running across the pedestrian section of the bridge.
Coliban Water General Manger Operations Neville Pearce said to avoid the likelihood of flood damage in the future the new pipelines have been installed using directional boring under the river.
“We have bored under the river on the upstream side of the road bridge and pulled the two pipelines through the bore to reconnect to the existing watermains on both sides of the bridge,” Mr Pearce said.
The section of boring is 160 m long and is 2 m below the lowest point of the river bed.Article continues below…
“This approach enabled us to minimise environmental impacts of the works and provides protection from the impacts of future flooding,” Mr Pearce said.
R&R McClure Excavations completed the works.
