Bio-swales are strips of vegetated areas that slow down and collect rainwater runoff, allowing it to infiltrate the soil, in addition to filtering pollutants. Bio-swales are important for climate change adaptation given the increase in storm frequency and scale that can result in polluted water overflow.

Primary Function

  • Collects and conveys storm water

  • Removes diffuse pollution from runoff with special plants

  • Improves groundwater infiltration (optional)

Added Benefits

  • Increased biodiversity

  • Reduces overheating (in comparison to paved areas)

  • Carbon sequestration

  • Improved urban quality

  • Communicates urban water dynamics
