Alternative Outlet Structure for Water Quality Detention Basins to Reduce Clogging

The Denver Metropolitan Area Urban Drainage and Flood District, in partnership with Colorado State University, will investigate an elliptical slot weir for metering water from settling ponds. Extended detention and full-spectrum detention basins improve the quality of stormwater runoff through settling of sediment. This is achieved by detaining and slowly releasing stormwater over a prescribed time. An alternative outlet metering device that is less susceptible to clogging and would require less frequent maintenance would be of great benefit to the Colorado Department of Transportation (CDOT) and other interested parties.
