Description

The Storm Sentinel® Catch Basin Insert is engineered to prevent sediment, debris, and other pollutants from entering storm drains while maintaining optimal water flow. This rectangular, cone-style model is equipped with an adjustable steel wire frame to fit a wide range of drain sizes—from 16"x20" to 28"x36"—and allows for quick, one-person installation without special tools.

Its geotextile fabric effectively filters out contaminated sediment, while overflow bypass ports handle high-flow storm events, preventing backups. The cone depth increases sediment and debris capacity without extending above the grate. Fully compliant with EPA, SPCC, and NPDES stormwater management regulations, this unit is reusable until water flow becomes restricted.
