Stormwater Quality Management

WWE’s work on stormwater quality management has earned the firm a nationally recognized reputation in this area of our practice. As one of the co-developers of the International Stormwater Best Management Practices (BMP) Database, WWE has assisted with compiling and analyzing data for more than 530 BMP monitoring sites across the country (as of June 2013). This has given us excellent familiarity with performance expectations for different types of BMPs and insight into design details that can contribute to the success or failure of a stormwater quality management project.

WWE has led the way with Green Infrastructure (GI) Low Impact Development (LID) in the mountain west, working with the Urban Drainage and Flood Control District (UDFCD) on criteria for our climate, monitoring innovative practices around the Denver metropolitan area and nationally and continually networking with colleagues around the country to stay on the cutting edge of stormwater treatment practices. While passive treatment technologies (BMPs, LID, GI) are suitable for stormwater quality treatment on many sites, in some cases, numeric stormwater discharge standards may apply (in particular for industrial sites). In these cases, WWE has extensive expertise in evaluating both passive and active treatment systems to achieve permit compliance.
