Catch Basin Insert

StormBasin™ Rectangular

The StormBasin is designed to capture and retain stormwater catch basin pollutants namely: sediment, trash, vegetation, nutrients, coliform bacteria, oil/grease and dissolved metals (e.g., lead, copper, cadmium and chromium).

 The large sediment and debris catch basin inserts provide ample storage volume for solids carried in stormwater flows – over 8 cubic ft in the 30″ x 48″ size. The catch basin insert design features a “hooded” bypass to reduce the potential for flooding during peak storm events while still retaining sediment and debris. The StormBasin also keeps the captured material dry, simplifying maintenance and reducing disposal costs.

Filter cartridges are available in various configurations allowing you to fine tune performance by targeting specific pollutants. The modular cartridge design allows quick and easy replacement while containing the spent material for safe transportation and disposal.

Features summary:

  • Replaceable filter cartridges can target specific pollutants
  • Durable, aluminum frame with large volume injection molded basin
  • Covered bypass retains trash during extreme rain events
  • Adjustable mounting system, long life, competitively priced and low cost of ownership

StormBasin™ Round

The Round StormBasin catch basin insert is a filtration BMP that employs Fabco’s proprietary filtration cartridges to remove fine particulate, hydrocarbons, heavy metals, organics and bacteria. The insert combines a gross pollutant trap with filtration technology for effective solid and dissolved pollutant capture. The sealed, non-serviceable filter cartridges contain various media to target specific pollutants of concern and are typically replaced bi-annually.
