Hydrologic and Pollutant Removal Performance of a Bio-Infiltration BMP.
Infiltration Best Management Practices (BMPs) have become a major component of stormwater designs (Traver 2003). These BMPs are designed to address runoff volume and quality criteria’s, augmenting and in some cases replacing traditional detention based methods. While the function of the Bio-Infiltration BMP’s may be understood, many questions remain on their design, maintenance, and how to best utilize these devices as part of a watershed plan. To address these issues, Villanova University has constructed and is monitoring a Bio- Infiltration “RainGarden” through the Villanova Urban Stormwater Partnership (VUSP). Flow data from this effort has been used to create a representative computer model of the watershed, allowing analysis of its performance (Heasom et al 2006). Results indicate that the site outperforms the original design specifications, and that maintenance may be required in the future to continue its high level of performance. Further information on the site is available through the Villanova Urban Stormwater Partnership website - www.villanova.edu/vusp.
