Constructed Wetlands are man-made systems that are designed, built and operated with a particular purpose and function in mind.
The two main purposes for constructing wetlands are for cost-effective wastewater treatment and stormwater sediment control.
Wastewater Treatment Wetlands (including sub-surface and surface flow) use natural processes to treat and dispose of wastewater to remove the waste contaminants and improve the quality of the water.
These wetlands can treat wastewater (sewage and effluent) from:
Stormwater Sediment Treatment Wetlands (including Stormwater Retention Ponds and Rain Gardens) reduce the contaminants in the stormwater or hold surface water runoff to reduce flooding and erosion, improving the quality of the water.
These wetlands can treat stormwater and trap sediment from:
