The precast sections are manufactured in easy-to-assemble components and are available in the same sizes as the In-Line Stormceptor® (eight models, ranging from 72 inch to 144 inch diameter). A customized insert with the extended weir separates the upper and lower chambers.
Submerged Inline Units
(STC 900, 1200, 1800, 2400, 3600, 4800, 6000, 7200)
- Extended weir and second drop tee height are custom designed based on tailwater elevation.
- Height of weir is set 9” above the standing water elevation.
Weir can be extended to a maximum of 45 inches from the outlet elevation (including the existing weir).
Inspect and maintain the Submerged Stormceptor® from the surface, without entry into the unit. Perform maintenance once stored volume reaches 15 percent of the Stormceptor® capacity, or immediately in the event of a spill.
Maintenance intervals vary depending on the application. Quarterly inspections should be during the first year of installation, so you can accurately establish a maintenance schedule.
Remove oil and sediment through the 24 inch diameter outlet riser pipe. Or you may remove floatables and hydrocarbons through the 6 inch oil inspection port.
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.
