This Stormwater Filter Sock is designed to control and treat runoff in areas where pollutants may enter stormwater systems, including in front of storm drains, around downspouts, and along gullies or drainage ditches. The durable woven polymer casing allows water to flow through quickly while the internal filtration media captures sediment, hydrocarbons, and other contaminants before they reach waterways. Its flexible design makes it ideal for both temporary and long-term stormwater management applications.

Each unit is supplied in 9-foot lengths and can be overlapped to provide extended coverage. Looped ends allow the filter sock to be easily staked in place for stability and also simplify handling and transport. Multiple media options are available to target specific pollutants, including an option for heavy-metal removal, helping facilities support compliance with NPDES, 40 CFR 122.26, and TMDL requirements.
