Description
The Storm Sentinel® Catch Basin Insert is engineered to stop harmful pollutants, sediment, and debris from entering storm drains, helping maintain compliance with EPA, SPCC, and NPDES requirements. This rectangular, cone-style model is equipped with an adjustable steel wire frame that fits drain openings from 16"x20" to 28"x36", ensuring a secure fit for varied basin sizes.
The no overflow bypass configuration forces all captured stormwater through the geotextile fabric, maximizing filtration efficiency. Its cone-shaped design increases debris capacity without interfering with grate placement, while installation and removal are fast, simple, and require no tools. The insert is reusable until it can no longer maintain adequate water flow.
