Aug 13, 2008 · Two popular structural BMPs are retention ponds and constructed wetlands. While many studies have evaluated the capabilities of retention pond and constructed wetland BMPs to reduce pollutant concentrations and loadings, few have focused on the internal mechanisms relating to the efficacy of these stormwater BMPs. Basins are generally used to collect stormwater and release it at a controlled rate to prevent flooding and erosion. Some basins can also filter some pollutants out of the water before it enters the storm drain system.
