Description
The Storm Sentinel® Catch Basin Insert delivers effective protection against pollutants entering storm drains. This round, bag-style model features an adjustable steel wire frame to fit drain openings from 22" to 24", enabling fast, one-person installation without special tools.
The no overflow bypass design ensures that all water passes through the geotextile filter fabric, effectively capturing sediment and debris even during heavy flows. Its low-profile placement beneath the grate keeps it unobtrusive, while its reusable construction offers long-term cost savings. Designed to comply with EPA, SPCC, and NPDES regulations, this model is an excellent choice for Storm Water Pollution Prevention Plans (SWPPP). Covered under U.S. Patent No. 10,384,155.
