integrated Water Resources Management
In Perth, 27% of mains water comes from reservoirs. Another 56% is pumped from ground water. The rest 17% comes from a seawater desalination in Kwinana.
Yes, the biggest part of Perth`s water is from underground. If you first come to this city, you might think that`s impossible. Especially there`s lots of parched area that doesn`t have a sprinkler system.
However, there is nearly150 km³ of water under Perth. It`s in various layers. Some of it has been there for 40,000 years.
