The 300 – 375 mm diameter sewer main will be constructed by Coliban Water and will cost $A650,000. Trenchless Technology will be used to install sections of the main including one road crossing, one rail crossing and a 130 metre section which crosses through the backyards of residential properties.

Coliban Water’s General Manager Operations and Headworks Neville Pearce said “With a number of streets potentially impacted by the works, laser guided and directional boring will minimise the impacts on properties and traffic flow.”

Contractor Austin Earthmoving has subcontracted Pezzementi Laser Boring to complete the trenchless sections of the project.

The project forms part of Coliban Water’s $214 million capital works program in its 2008-2013 Water Plan. Works on the project are expected to be completed by April this year.
