We have a long term plan in place to secure our water future for generations to come.
We first released our 50-year plan to secure Perth's water supply in 2009, in response to the early signs of a drying climate and with extensive consultation with the community. We followed this with a second 10-year plan in 2011.
Since the 1970's rainfall has reduced by around 19% but streamflow to dams has declined much more dramatically. Over the last decade, we have introduced new climate independent sources of water - seawater desalination and groundwater replenishment - to help secure supplies.
By 2030, providing our water use reduction and recycling targets are met, we expect a further 70 to 100 gigalitres of additional climate independent water will be required to support Perth's water needs.
Our plans to secure Perth's water supply into the future include:
- continuing to help Perth households and businesses use even less water and make greater use of recycled water
- expanding our Groundwater Replenishment Scheme and investigating further opportunity for reuse of treated wastewater
- increasing the capacity of our existing desalination plants
- expanding our deep groundwater network
- investigating new desalination plants at Kwinana and Alkimos.
