Description
Constructed wetlands are artificial wetlands with the main objective to harvest, treat and store storm water runoff in urban areas. Processes of natural wetlands are adapted to constructed wetlands focusing on water purification and storage. The established vegetation, soil and microbiological activity play an important role for the filter performance of constructed wetlands. Constructed wetlands can also help support urban biodiversity by including, for example, diverse vegetation and barrier-free shores.
Conditions for Implementation
- Suitable location with enough accessible land outside of floodplains with compact soils
- Near waste water source
- Topography should be considered (e.g. gentle slope to allow natural water flow)
- Biodiversity friendly design
