 What is a Raingarden?

Raingardens capture stormwater runoff directly from your roof or veranda through your guttering and downpipes. Once captured, stormwater is filtered through the garden bed, peak flows are reduced because stormwater is retained which diminishes erosion and pollution issues related to the ‘first flush’ of stormwater into our waterways.

How does a Raingarden work?

Beneath the surface of a Raingarden are a series of different sand and soil layers which capture pollutants. In a planter box Raingarden, a length of slotted pipe or ‘Ag Pipe’ runs along the bottom and captures filtered water and distributes it back into the stormwater system or directs it to be used elsewhere on your property. Plants which live and grow in the Raingarden also absorb and further filter out pollutants captured in stormwater flows.

Why build a Raingarden?

 By constructing a Raingarden in your backyard, you are creating a bioretention cell which cleans stormwater, reduces peak flows and provides habitat for insects and butterflies.
