Stormwater Interceptors

StormTrooper

Stormwater Interceptor

The StormTrooper® is the most advanced stormwater hydrodynamic separator (HDS) on the market. The StormTrooper® utilizes patented technology to remove sediments, trash, and oil from storm-water runoff. With thousands of installations worldwide, engineers rely on and include the StormTrooper® in their Stormwater Water Quality (SWQ) plan as required by EPA Clean Water Act. Stormwater runoff from urban areas carries pollutants and trash into the storm drainage system. Unlike sanitary sewer water, stormwater typically receives little treatment. Polluted stormwater eventually drains into public waterways, rivers, aquifers, lakes, and oceans. The pollutants include trash, debris, sediment, and hydrocarbons which could be harmful to the environment, both biologically and aesthetically.

Features

  • Wide range of models and capacities available
  • Customizable design to adapt to jobsite configuration
  • Prepacked system for easy installation
  • Oil removal through patented coalescing media
  • Simple maintenance
  • Coating options available 
  • Low and high flow capabilities

The function of the StormTrooper® system is to intercept free oil and sediment from stormwater runoff and retain them for periodic removal. Each system is designed for a rated flow rate of stormwater, known as the “first-flush” flow of a storm event. This first-flush contains the majority of the pollutants washed from catchment areas. Runoff will range from low to very high flow rates. High flows can be detrimental to stormwater treatment devices in that excessive flows tend to scour and resuspend the existing retained pollutants left from the previous storm event. The StormTrooper® utilizes engineered bypass features to handle excessive flows, permitting only the design flow through the interceptor while bypassing high flows to the storm sewer.
