StormTech + Green Infrastructure

Not Gray, Not Green, Right in Between

Green Infrastructure (GI) is a complementary, alternative system to conventional (or “Gray”) stormwater solutions that mimic natural hydrology. It seeks to improve water quality and reduce water quantity by capturing runoff as close to the source as possible (i.e. where the raindrop falls) and infiltrating, filtering, detaining, or otherwise storing the runoff for reuse.

Green infrastructure benefits include:

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.

StormTech + Green Infrastructure Applications

Pervious Pavement

Pervious pavement refers to paving methods for roads, parking lots, and walkways that allow the movement of water and air through the paving material.

Benefits of Using Pervious Pavement

Environmental:

  • May assist in groundwater recharge
  • Flood mitigation
  • Reduces runoff temperature

Safety:

  • Pervious pavement limits surface water
  • No black ice
  • Reduces hydroplaning

Economic:

  • Higher initial cost
  • Efficient land use
  • In colder climates, may save money on deicing salts

StormTech with Pervious Pavement

  • StormTech Chamber provides 100% void, increasing storage volume
  • Bare chamber volume allows increased storage
  • Enables the use of pervious pavement in areas with low soil permeability
  • Reduced footprint
  • Allows pretreatment in conjunction with Isolator Row PLUS

Rain Gardens + Bioretention

A rain garden is a shallow depression planted with suitable vegetation which is used to store and possibly treat stormwater runoff from impervious areas.

Benefits of Using Rain Gardens + 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
  • Increased storage capacity due to 100% chamber storage.
    • Enables the use of rain gardens in areas with low soil permeability.
  • StormTech system can act as an emergency overflow to the rain garden

Downspout Disconnections

A downspout is a pipe that directs stormwater runoff from the roof of a house to the ground.The StormTech chamber system can connect with roof downspouts for commercial and residential applications.

Benefits of Redirecting Downspouts

  • Reduces the volume of water that enters the system
  • Replenishes groundwater supply
  • Filter out sediment and nutrients from the water to decrease pollutants in streams
  • Allows you to harvest the rainwater for reuse

Rainwater Harvesting

 

Rainwater Harvesting is the collection and storage of rain, rather than allowing it to run off. Rainwater is collected from a roof-like surface and redirected to storage system.

Benefits of Rainwater Harvesting

  • Cost effective
  • Conserves water
  • Acts as a source of water for landscape irrigation
  • Reduces soil erosion and pollution of water bodies
  • Simple and easy to install and operate

StormTech Isolator Row PLUS

StormTech’s patented Isolator Row is a row of chambers wrapped in a geotextile which filters the stormwater trapping pollutants in the row.

Benefits of Using Isolator Row PLUS

  • Improves stormwater quality
  • Achieves a removal efficiency of 80% for TSS which meets most municipal recommended levels for water quality treatment
  • NJCAT Verification Report
