This plant helps Perth (a city of 2m people) get over half of its fresh water from desalination. We used to get most of our fresh water from the local aquifer and from dams, but this was totally unsustainable. The water table has been recovering over the past 10 years, and is on track to recover to pre-invasion levels in the next decade. By which time we should be at over 90% renewables for power too! Quite proud to be a West Australian really.
