Water recycling
Increasing the amount of water we recycle is essential to helping WA become more climate resilient. Learn more about water recycling in WA.
Learn moreTo protect our unique lifestyle in WA, we've had to understand the impacts of climate change and its varying effects across our region.
Learn more about climate change & WAAs our climate changes, so does our access to water. Depending on how much rainfall runoff flows into our dams, there are fluctuations in our water source mix. Alongside desalination, groundwater plays an important role in sustaining our water supply, delving into the earth's underground aquifers. To protect our lakes and wetlands and further secure our supply, we're investing in a deep groundwater network. This will allow us to continue to reduce our groundwater withdraw from environmentally sensitive areas.
We have had to adapt to the impacts of climate change to protect our unique WA lifestyle. By developing rainfall-independent drinking water sources, we're securing our water future. Learn about how climate change is impacting our state, our water sources, and our journey to a sustainable water cycle.

Water saving tipsDeclining rainfall is affecting the amount of rainfall runoff (streamflow) into our dams. Stay up to date with streamflow and rainfall data and find out how our water use is tracking.
Perth’s winter rainfall is predicted to decrease by up to 15% by 2030.
* Average monthly rainfall (for the period 1876 - 2016).
Dam volumes, rainfall and water use data is updated every working day, streamflow is updated weekly.
We're the largest water utility globally, by area serviced, on the world's driest inhabited continent. With this, we face significant climate change impacts. Find out how we've diversified our water sources to ensure a secure water supply.
Groundwater remains a vital water source, but its also under pressure due to climate change and increasing demand.

We're securing water sources for the regions for the future and maintaining infrastructure to ensure communities have reliable drinking water.
Our Partnerships and Education team are taking proactive steps towards education for sustainability.
We were the first utility in the country, and among the first in the world, to use groundwater replenishment. Stage 2 is now complete allowing us to recharge Perth's aquifers with up to 28 billion litres of purified recycled water each year.
