CONSTRUCTED WETLANDS FOR DIFFUSED POLLUTION
Constructed wetlands are extensively vegetated water bodies that use sedimentation, filtration and biological uptake processes to remove pollutants from storm water. They create diverse habitats and restore environmental characteristics of urban areas.
Treats runoff: coarse sediment, suspended solids, phosphorus, nitrogen, heavy metals
Delays peak rain from entering stormwater system
Reduces overheating (in comparison to paved areas)
Improved urban quality
Communicates urban water dynamics
