Melbourne Water – Raingardens

Raingardens receive stormwater from hard surfaces such as a downpipe from a roof, paved areas or driveways, slowing the rate of stormwater before it flows into drains and on to rivers, creeks and bays. In public spaces such as streets, parks and schools, raingardens also filter out litter, oil, excess nutrients, chemicals and sediment that normally build up on hard surfaces such as roads, car parks, roofs and driveways.

Melbourne Water’s General Manager of Waterways, Chris Chesterfield, said stormwater runoff from suburban streets was the main polluter of rivers, creeks and bays because of what it picks up and carries into waterways.

“Stormwater runoff can carry pollutants ranging from nitrogen that causes algal blooms, to motor oil and animal droppings that can affect the health of fish and platypus,” said Mr Chesterfield. “Raingardens are a great way to reduce the impact we have on our waterways, and they also make an attractive and water‐efficient feature to the landscape.”
