Perth’s water sources have changed over time due to climate change. We’re getting less rain, which means less water flowing into our dams. Over the past decade we’ve introduced new climate independent sources - seawater desalination and groundwater replenishment.
In 2017/18 the
Integrated Water Supply Scheme produced 312 billion litres of water for our customers, made up of:
- 48% Desalination
- 40% Groundwater
- 10% Dams

Declining rainfall means the water in our dams is no longer just made up of inflows from rain.
