The Curb Silt Bag Insert combines a version of the ENPAC Silt Bag and a Curb Inlet Filter to make the perfect Storm Sentinel® to prevent harmful pollutants from washing into storm drains. Storm water is filtered through the coiled filter of the curb inlet, while the silt bag filters pollutants entering the drop inlet. Double the filtration in one product!
- Easy installation and removal with handles
- Silt bag sits below the grate to be low-profile and unobtrusive
- Woven Geotextile fabric prevents contaminated sediment from washing into the drain
- Standard versions feature overflow bypass ports for high-flow storm events, preventing storm water backup around drains, optional no-overflow version available
- Reusable until product no longer maintains adequate water flow
- No special tools required for installation
- Complies with regulations when used in Storm Water Pollution Prevention Plans
