LASER-guided microtunnelling is being used to bore 2.3km horizontally and hit a target within 2cm of tolerance – and what’s at stake is 1.5 million litres of sewage a day.
The use of the technology, believed to be a first for Tamworth, is in the regional council’s $2.5 million sewer rising main project.
And this week, the project’s focus turned to the levee bank at the northern end of Peel St.
Contractors started boring under the bank from the river side to the street side, and from the rear of Tamworth Community College towards Jewry St.
The council’s water projects and services manager, Mick McGufficke, said these were “critical works” and “we had to step up the technology that we’re using to make sure we achieve the outcomes of the project”.
New, relocated pipes are being laid to avoid possible issues from upcoming road projects. The pressured system carries 1.5 million litres of sewage daily from the Darling St Pump Station to the higher Swan St Pump Station.
