Raingarden | Brisbane City Council



You can help protect our waterways by installing a raingarden in your yard, community, school or business.

Raingardens (also known as bioretention systems) are garden beds which use native plants and free draining soils to capture, filter and treat pollutants typically found in stormwater. Treatment occurs through a combination of natural physical and chemical processes associated with the type of soil and plants used.

Raingardens are a good alternative to traditional gardens or lawns. They can be any size or shape and can be incorporated into any garden. 

Benefits of raingardens

When it rains, water from roofs, driveways and streets flow into stormwater drains, through local waterways and to our beaches and bays. This runoff collects sediment, heavy metals, oil and grease which impact on the health of our waterways. These pollutants can also be harmful to fish and other marine life. 

By reducing the level of sediment, nutrients and other pollutants that enter our waterways, raingardens are an easy and economical way to help improve the health of our waterways.

Raingarden game

Learn about the benefits of creating a raingarden through Brisbane City Council's Filter Frenzy online game. Reduce the sediment and other pollutants in your garden before it enters the local creek and save the fish.
