Perth doesn't have the water issues that other major cities have because it already has a desalination plant providing a large chunk of the city's water supply needs.

And now the Western Australia State Government has announced a plan to build a second desalination plant. The $955 million facility will be built south of Perth near Bunbury. According to reports, it will cost $640 milliion to build and another $315 million to integrate it into the state's water supply system.

Perth's first desalination plant, a $400 million facility at Kwinana, was opened earlier this year. The second plant is expected to be providing water by 2011.
