Pay my bill
How Perth's water sources have changed over time
Climate change has dramatically affected where we get our water from. We can no longer rely on the rain to meet our water needs.
As we continue to feel the impacts of climate change, we have adapted. We are working with government, partnering with businesses and supporting the community to take action on climate changes.
