Derek Gee Installations Pty Ltd was contracted to our client McConnell Dowell JV on the Perth Desalination Project, located in Kwinana, Western Australia.

From 2005 to 2007, we employed up to 45 people on site for the installation of GRV underground services of mostly 1200 diametre pipe, 2.3 inlet and 1.6 outlet pipe fit ups, Reverse Osmosis building GRV fit out, installation of membrane filters and installation of GRV in the DMF building.

We played our part in delivering the project on schedule and under budget, which contributed to the project winning numerous national and international awards including the International Desalination Association’s International Desalination Plant of the Year.

Project Background

The plant has an initial daily capacity of 140,000m³ with designed expansion to 250,000m³/day, at the time this made it the largest of its kind in the southern hemisphere and the biggest in the world to be powered by renewable energy.

The plant produces 45 gigalitres (forty five billion litres) of fresh drinking water a year – around 17% of Perth’s water supply which makes it the largest single contributor to the area’s integrated water supply scheme.
