Perth's water supply

As our climate changes, so do our sources and the way we supply water.

Climate change is having a profound impact on our water supply. This means we can no longer rely on the same amount of rainfall from years gone by to flow into our dams. We now depend on other sources of water like seawater desalination, groundwater and groundwater replenishment. In future, more water will come from these sources.
