In-Line Stormceptor®

The Inline Stormceptor is the standard design for most stormwater treatment applications. The patented design allows the Inline unit to maintain continuous positive treatment of stormwater for the removal of pollutants such as total suspended solids (TSS), free oils and nutrients year round, regardless of the flow rate.

In-Line Stormceptor®

Uses & Applications

Stormceptor is applicable in a variety of development situations including:

  • Stormwater quality retrofits for existing developments
  • Industrial and commercial parking lots
  • Automobile service stations and truck stops
  • Airport and military installations
  • Areas susceptible to hydrocarbon spills
  • New residential sites and re-development in the urban core
  • Pre-treatment to LID designs (as part of a treatment train)

The In-Line unit is available in eight different unit sizes, ranging from 900 to 7200 gallon storage capacities. Each unit is constructed from precast concrete components and a patented fiberglass insert.

Single Inline Unit

(STC 900, 1200, 1800, 2400, 3600, 4800, 6000, 7200)

  • Frame and cover are orientated directly over riser pipe and oil port.
  • Can be utilized as a bend structure.
  • Minimum direction change from inlet to outlet is 90 degrees.

Multiple Inline Unit

In-Line High Flow

High Flow

  • Frame and cover should be orientated directly over riser pipe and oil port.
  • Accommodates multiple horizontal inlet pipes.
  • Can be utilized as a bend structure.

Minimum direction change from either inlet to the outlet is 90 degrees.

Inspect and maintain the In-line 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.
