TAPE GULD Approved Biofilter

StormGarden is a TAPE GULD Approved Low Impact Design (LID) micro-bioretention system that has been engineered for high flow treatment and high pollutant removal. The high flow-through rate of the engineered media results in a much smaller footprint than traditional bioretention systems, thus treating the same amount of stormwater runoff at a fraction of the cost.

StormGarden is unique in that it has a “Runoff Reduction Infiltration Panel” that allows a portion of the runoff to infiltrate into the ground thus replenishing the groundwater supply and reducing the volume of runoff discharging downstream. The panel also allows the unit to completely drain between storm events to prevent bacteria growth and nitrogen release during the next storm.

How it Works:

Stormwater runoff enters the StormGarden unit through a curb inlet opening and flows down through the engineered filter media mixture that is contained in a landscaped concrete structure. The filter media captures sediment, nutrients, metals, and hydrocarbons and removes them from the runoff. The stormwater runoff flows down through the media and into an underdrain pipe at the bottom of the structure, where the treated water is discharged. However, a portion of the treated water exits the structure through the infiltration panel into the surrounding soil.

Benefits of StormGarden:

  • TAPE GULD Certified
  • 20% to 30% smaller footprint than the competition due to a higher media flow-through rate
  • Increased pollutant removal efficiencies due to runoff reduction capabilities
  • Factory-installed bio-media ensures that the system will perform as designed
  • Precast or cast-in-place installation options
  • Easily maintained by local landscaping companies
  • Variety of configurations
  • Integrates into most sites & landscape plans
