Perth Seawater Desalination Plant

SECURING PERTH’S WATER SUPPLY WITH ONE OF THE LARGEST DESALINATION PLANTS IN THE SOUTHERN HEMISPHERE

Facing severe drought in April 2005, Western Australia's Water Corporation formed an alliance with SUEZ and Multiplex. The alliance designed, built (a joint venture between SUEZ and Multiplex) and will operate and maintain Perth’s first seawater desalination plant for 25 years. The plant uses reverse osmosis technology and is the first large scale desalination plant in the southern hemisphere.

The reliable and innovative plant is in Kwinana, 25kms south of Perth, and was commissioned just 18 months after the project was awarded, in November 2006. With a capacity of 144 MLD the plant is able to produce up to 17% of Perth’s drinking water, making it a critical piece of infrastructure in the fight against ongoing issues with drought.

During the operation phase, the plant has run consistently 24-hours a day, and for more than 2,800 days without lost time due to injury. There have been no unscheduled shutdowns since 2008 and more than 200 billion litres of water has reached the taps of the people of Perth. The plant has also delivered above its nominal capacity of 45GL, with 52GL been produced in 2010/11 to help address the drought with minimal environmental impact.
