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!
