Have your say - securing Perth’s water supply

Future planning for Perth’s already vast water supply scheme is a job that will never end for the Water Corporation. It’s essential the scheme keeps pace with climate change, annual water demand and projected growth.

We have planned ahead to secure water supplies producing 50-year plans (published in 2009) and a 10-year plan (published in 2011) under the Water Forever title. These plans are based on a three-pronged approach to develop new water sources, reduce water use and increase water recycling.

You can read more about our plans to secure Perth's water supply via Water Corporation's website.

But water supply planning is not static - it is about responding and adapting to changing circumstances - and identifying and adding new sources of water when needed.

In late 2017 we started to look at the feasibility of new desalination plants north and south of the Swan River, one near Kwinana close to the existing Perth Seawater Desalination Plant and the other in the northern suburb of Alkimos.

We invite you to learn more about our investigations and how you can stay updated as we seek environmental approvals.

When will a new water source be needed?

At this stage there is no firm timeframe for building a new desalination plant for Perth’s Integrated Water Supply Scheme. The timing depends on annual rainfall and how fast our climate continues to dry; how much water we use each year and population growth. We constantly keep an eye on all of these factors, and when the time is right, we will start the process to add a new source to the Scheme, which may be one of the plants we are investigating or another option.
