A 50 year plan to deliver sustainable water and wastewater services.

Creating a Portfolio of Water Options

Water Forever has created a portfolio of water options to help make Perth more climate resilient.

By 2060, working in partnership with the community, the Water Corporation will:

  • help to reduce water use, so we all use a quarter less water than we do now;
  • support the recycling of up to 60% of wastewater in the Perth-Mandurah area; and
  • prepare a diverse array of potential water sources for future development. 

Based on a planning assumption of reduced rainfall combined with a growing population, the Water Corporation estimates that an additional 120 gigalitres of water will be required by 2030 – more than 40% of current annual water use.

By 2060 it is forecast that Perth and connected towns will need an additional 365 gigalitres – some of this will need to replace existing sources affected by declines in rainfall and the balance will be needed to meet the projected growth in demand.

By reducing the amount of water used, recycling more water and developing new water sources, the Water Corporation will ensure that there is enough water to meet future needs, even in a drying climate. The table below outlines the portfolio of new options that have been identified for the next 50 years, in addition to existing sources.
