Rain Gardens in Melbourne

Melbourne Water has been working with local councils and the community to build raingardens in public spaces such as streets, parks and schools. The 10,000 Raingardens Program aims to encourage people to build raingardens in their homes. We love this idea and would like to see it implemented here in New Zealand. We found some New Zealand information on rain gardens, but once again the Australians are leading the charge.

What is a Raingarden?

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 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?

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.

Tanksalot’s raised garden beds provide a quick, easy, and aesthetic way to create a raingarden at your home. Raingardens use water efficiently and help protect rivers and creeks.

Melbourne Water is aiming to have 10,000 raingardens installed in the Melbourne area, to help reduce pollution in waterways.

You can find lots of information, including a great how-to video with Trevor Cochrane form the Garden Gurus, at the Melbourne Water Raingardens website here.
