Create a raingarden in your backyard to help protect our rivers and creeks

A raingarden is a water saving garden that is similar to a regular garden bed, but is designed specifically to capture stormwater from hard surfaces such as driveways, patios and roofs via downpipes after it rains.

Raingardens are changing the way Australians think about gardening and are rapidly becoming an important part of garden design, particularly in Melbourne. They can even be positioned to capture overflow from a rainwater tank.

How do raingardens work?

This short video gives a concise overview about how a typical raingarden works.

Beneath the raingarden are layers of sandy soil which help to slow the rate of stormwater entering our rivers and creeks.

These layers also assist in the removal of pollution, such as

  • nitrogen and phosphorus,
  • fertilisers, dust, leaves
  • and animal droppings which are washed off these hard surfaces.

The plants in your raingarden help to further filter out pollution that would otherwise end up in our rivers and creeks.

By capturing stormwater, raingardens are self watering and are therefore easier to maintain and use less drinking water than regular gardens.

Raingardens are rapidly becoming an essential addition to any sustainable garden design, thanks largely to the fact that they come with a serious benefit to the environment and the health of local rivers and creeks
