Curb Inlet Filters

Stormwater Curb Inlet Filters

Our patented Curb Inlet Filters are a stormwater Best Management Practice (BMP) to block debris like leaves, litter, plastic bottles and cigarettes from entering the stormwater system. By allowing water to flow while capturing pollutants, they help reduce flooding, cut maintenance costs, and protect local waterways.

Tailored to fit a wide variety of curb openings for a seamless install and reliable performance.

A detailed 3D render showcasing the SOP Technologies patented stormwater filter. Its innovative upward-flow, louvered design effectively captures debris while maximizing water flow and preventing clogging.

Shown here is our patented curb inlet filter fitted into a standard curb opening. Each unit is custom-designed for durability, optimal flow performance, and precise integration with site-specific stormwater infrastructure.

    • Blocks stormwater pollution at the source. Each filter can prevent hundreds of pounds of leaves, street litter, and debris, including phosphorus and nitrogen, from entering waterways every year.

    • Reduces contaminants like cigarette butts, plastic bottles, and other street litter from flowing into rivers, lakes, and oceans.

    • Supports healthier ecosystems and compliance with environmental standards by achieving TMDL reductions for NPDES / MS4 permits. Proven to reduce Total Phosphorus (TP) and Total Nitrogen (TN) loads.

    • Prevents clogged pipes and storm drain backups by keeping leaves and litter out of stormwater catch basins.

    • Reduces the frequency and cost of stormwater system maintenance, saving cities like Aventura up to $97,000 within 10 years by making street sweeping more effective than costly vacuum cleanings.

    • Designed to retrofit easily into existing or new infrastructure, with filters customizable to any size inlets and allowing for high water flow with an upward-flow, louvered design.

    • Minimizes flooding on streets and around properties by preventing leaves and street litter from clogging stormwater inlets, pipes, and drains, while allowing free flow of stormwater.

    • Helps cities save money by reducing the need for expensive catch basin cleaning compared to street sweeping.

    • Contributes to safer, cleaner, and more livable neighborhoods through public education and communication with the included QR Code Storm Drain Markers, enabling community members to report issues and learn about local pollution prevention efforts.
