Submerged Stormceptor - Drop Pipes
The Submerged Stormceptor can accommodate a partially or fully submerged pipe application. Submergence is common in areas close to lakes, rivers, coastal areas and areas with high groundwater tables. The insert in these applications has a custom weir height and second drop pipe set at the existing water elevation. Both the weir height and the height of the second drop pipe are site specific depending on the level of submergence. The second drop pipe elevation corresponds to the actual submergence elevation while the weir is built to be 9” higher than the submergence elevation.
The Submerged Stormceptor® system removes total suspended solids, free oil, and other pollutants from stormwater run-off in partially submerged pipes.
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 weir separates the upper (by-pass) and lower (treatment) chambers.
Submerged Inline Units
- Extended weir and second drop tee height are custom designed based on tailwater elevation.
- Height of weir corresponds to the difference of outlet invert and tail 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.
The requirements for the disposal from Stormceptor are similar to that of any other Best Management Practice (BMP). Consult local guidelines or your Stormceptor® area marketing manager prior to disposing the separator contents.
The Submerged Stormceptor® has been successfully installed in coastal areas and other submerged pipe conditions.
