Description
The Storm Sentinel® Catch Basin Insert delivers dependable storm drain protection by preventing sediment and other harmful pollutants from entering waterways. This round, bag-style framed model comes with an adjustable steel wire frame for a secure fit in multiple drain sizes, allowing quick, one-person installation without special tools.
This version features no overflow bypass, ensuring that all stormwater passes through the filtration system. The low-profile design allows it to sit below the grate for minimal visibility while providing maximum protection. Made from 8 oz. non-woven geotextile fabric, it captures contaminated sediment effectively and is reusable until water flow performance declines.
Fully compliant with Storm Water Pollution Prevention Plan (SWPPP) requirements and built for long-term reliability, this unit meets stringent EPA, SPCC, and NPDES regulations.
