This drop inlet filter can remove stormwater pollution

The Gutter Bin Drop Inlet Filter (DIF) stormwater filtration system was featured at the company's booth at the 2025 Ohio Stormwater Conference in Sandusky, Ohio. It is a filter that can remove stormwater pollution within a drop inlet type storm drain. It features a patented design that offers multiple service methods including by vacuum truck, manual field crew or garbage truck.

The filter has an adjustable frame and filter, and fits almost any shape drop inlet storm drain (flat, bent, rectangular and round). The product is manufactured in the USA and features a 3-year warranty and is compatible with nyloplast type drains.

The filter has an adjustable backflow preventer that inhibits scouring and the loss of captured flotable pollutants. The filter can be cleaned quickly by hand or machine with a service interval of 1-2 times/year depending on environment and filter option choice. It is compatible with retrofits and new builds and no drilling or special tools are required for installation.

The system can produce results that align with the U.S. Environmental Protection Agency's (EPAs) NPDES Best Management Practices guidance.
