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.

Primary Function

  • Treats runoff: coarse sediment, suspended solids, phosphorus, nitrogen, heavy metals

  • Delays peak rain from entering stormwater system

Added Benefits

  • Increased biodiversity

  • Reduces overheating (in comparison to paved areas)

  • Carbon sequestration

  • Improved urban quality

  • Communicates urban water dynamics
