Assessment of Underground Stormwater Management Devices

Tuesday, October 2, 2007 - 9:15am

About the Event

Underground proprietary devices have become popular stormwater best-management practices in urban areas because of their small footprints. For more than a decade they have been monitored by different agencies and consulting firms to verify their capabilities in removing suspended solids. The disparity among the results of field monitoring studies has been so drastic that it has made it difficult to assess the performance of these devices.

A simple repeatable laboratory testing method was developed in 2005 to evaluate these devices under treatment flow conditions. In 2006, the laboratory testing was expanded to assess the performance of these devices in the field. In this presentation, the results of laboratory testing of two devices and field testing of four other devices will be presented.
