Koorlong Wastewater Plant

Water & wastewater

Client: Lower Murray Water

Contract value: AU$34m

Contract type: Design and construction, Joint venture

Completion date: 2010

As communities expand, so does the demand on water supplies.

Our client, Lower Murray Water, commissioned the Koorlong WWTP (KWWTP) Augmentation Project as one of several projects to help supplement or reduce irrigation water extractions from the Murray River in Victoria, Australia.


The new KWWTP caters for growth and provides facilities for the treatment and re-use of sewerage for Koorlong, through to 2020. It has been designed to cater for combined domestic and trade waste from three catchments, of Mildura, Merbein and Red Cliffs. The project involved increasing the plant’s capacity, from 3.5m L/day to 11.85m L/day.

Throughout the project, Fulton Hogan moved 45,000m³ of earth, and used 8,500m³ of concrete and 1,600 tonnes of reinforcing steel.

Fulton Hogan understood the client’s need to continue processing waste throughout the construction and work was carried out effectively, while allowing for the plant to remain fully-operational.

Environmental management

We also worked closely with our client to achieve their goals of reducing greenhouse gas emissions through their activities and also ensuring that the design had energy-efficiency, recycling capacity and carbon-reducing measures.

The new KWWTP is capable of meeting the treatment and disinfection effluent quality criteria, outlined in the Victorian Environmental Protection Authority (EPA) Guidelines for Environmental Management – Use of Reclaimed Water (2002).
