Water is a precious and finite resource that we can’t take for granted. Know the basics, so you can join the discussions shaping Melbourne’s water future.
Melbourne has some of the cleanest and highest-quality drinking water in the world, which Melbourne Water manages and protects on behalf of the community. Melburnians have been great water savers since the Millennium Drought. But there’s more we can do to protect all aspects of the water cycle – read on and learn how it relates to you.
Where does our water come from?
Less than 1% of the earth’s water is available to drink.
Around 97% of earth’s water is in our oceans, making it unsuitable to drink. Much of the freshwater on our planet is stored in glaciers and ice caps.
Population growth, urban development and climate change are affecting the quality and quantity of fresh water available globally.

So we can’t rely on building more dams.
Instead, we need to:
- make the best use of all water available, and use it more efficiently
- look at alternative water sources such as recycled water, groundwater and stormwater
- use our desalination plant to help build and maintain a buffer of water in our storages.
Where does our water go?
Sewage is around 98% water.
It’s easy to forget about water once it’s flushed down your toilet or drain – known as sewage.
And because sewage contains everything that goes down the drain when you wash your dishes, bathe, throw on a load of washing or flush the toilet, it’s actually around 98% water!
Think about the water around you…
Increased development in Greater Melbourne means there more hard surfaces that do not soak up rain when it falls. This means there is more stormwater flowing quickly from our suburban streets into our rivers and creeks.
To reduce impacts of stormwater on the health of Port Phillip Bay, Melbourne Water uses constructed wetlands and raingardens.
