Runoff Quality Enhancements in Wet Detention Ponds

Document Type: Proceeding Paper

Part of: Engineering Hydrology

Abstract:

Wet detention/retention ponds are designed to reduce peak discharge and improve water quality for urban runoff. These ponds remove particulate and dissolved pollutants by sedimentation, physical and chemical interactions and biological processes. Suspended removal efficiencies may be correlated with detention time, pond configuration, storage volume and exit weir operation and design. Sedimentation rates per year are correlated with the ratio of pond surface areas (SA) at the permanent pool divided by the drainage basin area (DA).
