A bioswale is a vegetated, linear and low-sloped structure often established in urban areas, near or between roads, with the objective to reduce flood risk during or after heavy rain events. Bioswales absorb, store and convey surface water runoff, and remove pollutants and sediments, as the water trickles through the layers. If properly planned and planted with deep-rooted native vegetation, a bioswale can both contribute to local storm water management and help support biodiversity.

Conditions for Implementation
  • A large enough area so that bioswales can be an effective part of the stormwater management system
  • Water collection system (e.g. from roofs and paved areas)
