Bioswales are landscape elements designed to concentrate or remove debris and pollution out of surface runoff water. They are a natural filtration system that consists of a swaled drainage course with gently sloped sides and is filled with vegetation, compost and/or riprap.

Bioswales have tremendous environmental benefits as they can reduce polluted stormwater runoff from roads and treat the stormwater. This is safer and healthier for the community and helps prevent contaminated stormwater from entering waterways.

With urban areas generating as much as 20 times more runoff than natural landscapes, these bioswales minimize erosion, and filter and cleanse runoff from roads in a small footprint using carefully placed vegetation, plants and soils.
