BMP Products started primarily as a manufacturer of NoFlood Filters; a flood proof storm drain insert. Understanding that clean storm drains guarantee clean waterways, we embarked on a mission to create a product that could effectively prevent water contamination, and the NoFlood filter was born! The NoFlood Filter is a storm drain insert that is custom manufactured to fit any type and size of storm drain. Our unique drop-in filter design has been shown to significantly reduce hydrocarbons including motor oil, diesel oil, vegetable oil, emulsified oils, and polynuclear aromatic hydrocarbons, along with collecting sediment and trash. All NoFlood Filters are hand made to your exact specifications in our warehouse, using our quality control criteria. The NoFlood Filter is the only insert for storm drains that won't flood! Our special patent-pending design and material, allows the NoFlood Filter to have a faster flow rate than the grate system itself!
