Title

Side-By-Side Evaluation Of Stormwater Proprietary Bmps

Abstract

This paper presents a side-by side study to determine the relative pollutant removal effectiveness of three proprietary end-of-pipe BMPs, namely, Baysaver, CDS, and Stormceptor. In this study, a controlled laboratory conditions were used in order to provide documentation of the performance of the BMPs. For that purpose, a lab facility was constructed at the University of Central Florida (UCF). The setup of the facility has the ability to pump flows required to replicate runoff events. Using this type of setup enables the relatively rapid testing of BMPs to evaluate their performance, under repeatable and consistent conditions for multiple flow rates, different constituents, particle sizes, and sediment concentrations. In this study, five tests were conducted with five different flow rates: 1.6, 1.28, 0.96, 0.64, and 0.32 cfs. The studied pollutants were sediments (TSS, TDS, and Bed load), nutrients (nitrogen and phosphorous), Metals (Fe, Cu, Zn, Cr, Ni, Cd), and litters such as organic leaves, soda cans, plastic bottles, and cigarette butts and boxes. The results showed that some of the pollutants decreased in concentration while others increased between the influent and the effluent of the units. The results also showed that the performances of the studied BMPs for the pollutants varied. Baysaver had the lowest TSS removal efficiency. Even though TSS removal efficiencies of CDS and Stomceptor were higher than Baysaver, they were still relatively low. All the units had good performance in removing the large sediment particles and litter. The results also suggested that nitrogen was produced in the Stormceptor unit during the testing program. Other than removal efficiencies, the paper also presents some factors that should be considered in BMP evaluation. The review engineer will need to decide which factors to include in an evaluation and their respective importance to the user. © copyright ASCE 2005.
