About The Project

We’re delighted to have been chosen by Melbourne Water to deliver a world-first solution for the rehabilitation of the Western Trunk Sewer (WTS).

We’ll be relining a 4.4km section of the existing sewer main using a technique known as slip-lining. And while the technology itself isn’t new, the challenge is, no one’s ever done it with such a large diameter pipe – in this case, 4.3 metres – AND in live flow conditions.

The Western Trunk Sewer is one of Melbourne Water’s most important assets, transferring approximately 57 per cent of the city’s total annual wastewater flow.

This project adds to the diverse portfolio of work we’re currently delivering for Melbourne Water.

We are looking for a Senior Contract Administrator to join our Western Trunk Sewer project based at the Western Treatment Plant in Werribee, just about halfway between Geelong and Melbourne.
