Project details

The Thiess Degrémont Joint Venture was contracted by AquaSure to design and construct the Victorian Desalination project in Wonthaggi. The project was for Victoria's Department of Sustainability and Environment, and is one of the biggest infrastructure projects in the state's history.

Thiess Degrémont designed and constructed Australia's largest desalination plant, associated marine tunnels and structures, an 84km water transfer pipeline and a co-located underground powerline to supply power to the plant.

The plant is capable of supplying up to 150 billion litres of drinking water each year - about a third of Melbourne's annual water needs - with the capability of future expansion to 200 billion litres.

The project was a key part of the State Government's Water Plan to save, recycle, distribute and create water. The plant operates with a 100% renewable energy offset, which lead to the construction of new wind farms in Victoria by AGL.

Thiess was also awarded the Victorian Desalination Plant - Operations and Maintenance contract.
