Description
The Storm Sentinel® Catch Basin Insert offers a reliable solution for keeping harmful pollutants from entering storm drains. This round, cone-style framed model features an adjustable steel wire frame that fits drains from 25" to 28" in diameter, ensuring quick, one-person installation without special tools.
Designed with no overflow bypass, it forces all incoming stormwater through the 8 oz. non-woven geotextile fabric, effectively filtering contaminated sediment and debris. Its low-profile position beneath the grate makes it unobtrusive yet highly efficient. The product is reusable until water flow capacity declines and is fully compliant with EPA, SPCC, and NPDES regulations.
Ideal for use in Storm Water Pollution Prevention Plans (SWPPP), this model also supports the optional oil-absorbing Spilltration® sorbent insert for hydrocarbon capture. Covered by U.S. Patent No. 10,384,155.
