BIO-SWALES

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
