An Experimental Study on the Use of Constructed Wetlands for Stormwater Management

Document Type: Proceeding Paper

Part of: North American Water and Environment Congress & Destructive Water

Abstract:

The purpose of this study is to compare the pollutant removal effectiveness of selected wetland vegetation such as cattails, reeds, and bulrushes by using laboratory bucket wetlands. Pollutants monitored include total phosphorus (TP), orthophosphate (UP), Zinc (Zn) and chemical oxygen demand (COD). The results verify that the removal rates for bucket wetlands are comparable to those in the literature. A modeling analysis was done with the bucket system data. Results obtained indicate that a simple model, VirginiA Stormwater WETland Simulation model (VASWETS), developed in the study has the ability to estimate the removal efficiencies for the three vegetation types examined, and for different design scenarios such as various pond/wetland ratios and detention times.
