Western Treatment Plant – Project Profile

May 2, 2018

Project overview

Located in Werribee, in Melbourne’s west, the 10,500 hectare Western Treatment Plant is a world leader in technical and environmental innovation. It processes around half of Melbourne’s sewage and produces nearly 40 billion litres of recycled water a year.

The Western Treatment Plant treats about 60% of Melbourne’s sewage. It serves about 1.6 million people in the central, northern and western suburbs.

The Werribee Pipeline delivered an upgrade to the previously existing Class C recycled water supply system. It is a 5.4 kilometre, 1m diameter Glass Reinforced Plastic pipeline.

The Western Treatment Plant was constructed with recycled glass

Between June and August 2011, Alex Fraser Group supplied over 15,000 tonnes of 5mm Recycled Glass to the project as pipe bedding and backfill material the pipeline. This was the largest project to have used recycled glass as a sand source and the consistency of the material was critical to its success on the project.

Cost and carbon savings

By choosing Alex Fraser Recycled Sand, Melbourne Water both contributed to saving natural sand sources and prevented glass waste from being stockpiled in landfill.
