Being located on one of Australia’s best groundwater resources – the Gnangara groundwater system – supports Perth as a modern, vibrant and green city that provides a lifestyle we all enjoy.

A system out of balance

Over the years, south-west Western Australia has become hotter and drier due to climate change. It’s common knowledge that this means less inflow to dams but it also means less recharge to groundwater. Being located on one of Australia’s best groundwater resources has allowed Perth to become a modern, vibrant and green city that provides a lifestyle we all enjoy. Now, with reduced rainfall and ongoing groundwater use, the groundwater system has shifted out of balance and our once healthy system is under strain.

Let’s rethink, innovate and collaborate

By working together and rethinking how we interact with water, we can secure our groundwater in a drying climate to help create a liveable, sustainable, productive and resilient Perth for the long term.

Our community, local governments,  and the Water Corporation have taken steps to respond to climate change by being more efficient and seeking alternative supplies. But more is needed if we are to rebalance the system as a whole. The Department of Water and Environmental Regulation has the state government responsibility for managing the state’s water resources and we are now working with water users to prepare the next Gnangara groundwater allocation plan.
