Best Management Products (BMP) is a company that specializes in stormwater quality improvement systems. Their catch basin hoods and filters are designed to keep stormwater systems effective by skimming off floatable debris and free oils, while allowing heavy particles to sink in a sump structure. BMP's flagship product, the SNOUT, is a vented hood or trap that separates pollutants that float (like trash and oils) from pollutants that sink (like sediment and grit). The SNOUT system has been installed in over 100,000 projects since 1999 and has been used by cities, major corporations, the U.S. military, and government installations. BMP also offers accessories like the Bio-Skirt for increased hydrocarbon capture and the Turbo Plate to reduce turbulence and increase sediment capture.
