StormTech and Stormwater Quality

StormTech’s Isolator® Row is a row of chambers wrapped in a geotextile which filters the stormwater

trapping pollutants in the row. The Isolator Row Plus provides a way to inspect and maintain the system

ISOLATOR ROW PLUS

• The frequency of inspection and maintenance varies by location. Contact StormTech for assistance with inspection and maintenance scheduling.

  StormTech and Recycled Materials

  Recycled Concrete Structural Backfill

• Thermoplastic structures utilize aggregate for conveyance, strength and volume.

• Recycled, crushed concrete can be an excellent structural backfill.

• The StormTech chamber system can connect with roof downspouts for commercial and residential applications.
  
  Bioretention

• Pollutant Removal – TSS, Phosphorous, Metals, Nitrogen, Hydrocarbons

• Groundwater recharge

• No standing water (proper design will allow water to infiltrate in a specified amount of time)

• Preserve pre-development hydrologic cycle

• Efficient land use & Aesthetics

  Hydraulics:

  • Soil infiltration rate

  • Design flow rate (potential for erosion)

  • Maximum ponding depth in rain garden

  • Optional overflow bypass

  • Proximity to buildings

  • Flood mitigation

  • Reduce runoff temperature

  Maintenance

• Routine vacuum sweeping and/or jet hosing is required to prevent clogging which can reduce the infiltration rate of the pervious pavement.

• Installation of pervious pavement must be staged so no erosion or sediment debris enters pavement.

  StormTech with Pervious Pavement

• StormTech Chamber provides 100% void,

  increasing storage volume

• Bare chamber volume allows increased storage. Relying only on stone does not provide long-term factor of safety.

• Enables the use of pervious pavement in areas with low soil permeability.

• Reduced footprint

• Allows pretreatment in conjunction with Isolator Row Plus

General Design Considerations

Always refer to local design specifications for

pervious pavement design guidelines.

Save Valuable Land and Protect Water Resources

StormTech + Green Infrastructure Benefits

When used together, StormTech chambers and green infrastructure offer the most cost-effective method to save valuable land and protect water resources. Together they allow for a design that both treats a required water quality volume, while also providing attenuation for peak flow volumes.
