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.
Collects and conveys storm water
Removes diffuse pollution from runoff with special plants
Improves groundwater infiltration (optional)
Reduces overheating (in comparison to paved areas)
Improved urban quality
Communicates urban water dynamics
