Performance of Stormwater Products and Practices: Why it Matters.

Upwards of 75% of developed land in the United States was urbanized prior to stormwater regulations and the existing stormwater infrastructure was given a “D” grade by the American Society of Civil Engineers. There are many challenges to regulating stormwater runoff, including variable timing, duration, and magnitude of rainfall; variable landscapes producing variable water quality, and receiving water resources with different susceptibilities to volume and water quality impacts, among others. Even sampling of stormwater runoff is fraught with uncertainty and inaccuracy, making compliance with target performance or effluent concentrations challenging. These challenges are exacerbated by changing climate, continuous development and urban sprawl, and limited investment in stormwater infrastructure implementation, operation, and maintenance. As a result, stormwater practitioners have sought and developed testing methods for measuring performance of individual stormwater products and practices, both in the laboratory and in situ (in the field). The importance of measuring performance accurately cannot be overstated, and unbiased, verified performance data is invaluable to the stormwater industry.
