The Inlet Stormceptor® is designed to accept Stormwater from either on top through a grated cover, from the side in a storm line or both. The Inlet Stormceptor design operates in the same manner as the inline unit, providing continuous positive treatment, and ensuring that captured material is not re-suspended.
Please be aware that all products are not available at every plant. Contact your local plant for specific project requirements.
The Inlet Stormceptor® is a 48 inch diameter precast concrete structure with a patented fiberglass insert. The insert extends into the treatment chamber, providing dual wall containment of hydrocarbons.
(STC 450i only)
- Grated opening at surface.
- Grated opening oriented directly over orifice plate/drop tee assembly.
- Outlet is oriented 180 degrees to orifice plate/drop tee assembly.
- Accommodates up to three horizontal inlet pipes.
- Useable as a bend structure.
- Minimum direction change from horizontal inlet to outlet is 90 degrees.
- Minimum depth from finished grade to outlet invert (contact your local Stormceptor® Representative).
Inspect and maintain the Inlet Stormceptor® from the surface, without entry into the unit. Ideally, perform maintenance once the stored volume reaches 15 percent of the total volume in the lower chamber, or immediately in the event of a spill.
Maintenance intervals vary depending on the application. We recommend quarterly inspections during the first year of installation to accurately establish the maintenance schedule.
Disposal requirements for pollutants captured are similar to that of any other Best Management Practice (BMP). Consult local guidelines or your local Stormceptor® Representative for additional information.
The inlet Stormcetor provides continuous treatment for all flows entering the unit. During infrequent high flow events (less than 10 percent of all storms), storm water flows over the diverting weir and enters the downstream sewer system, preventing scouring of previously trapped pollutants. The design of the internal weir prevents previously collected pollutants from scour and re-suspension while still allowing treatment throughout the entire storm event.
The Inlet Stormceptor® is an excellent Best Management Practice, since it saves the designer the cost of providing a traditional inlet structure upstream of a conventional treatment device in small drainage areas. The Inlet Stormceptor® is available across North American as a sediment and spill containment device, and has been successfully used as a stand alone treatment device or as part of a treatment train.
