Stormwater LID

Meet Low Impact Development (LID) Goals

Low impact development (LID) seeks to remove the negative impact of development by mimicking the pre-development hydrology of the project site. The old strategy only matched the peak flow rates, while the LID strategy reduces the volume of runoff produced by development.

Efficient land utilization is at the heart of LID, because it takes into account the inherent value of the land and the benefits of preserving the natural landscape. Installing underground StormTrap systems can contribute to LID goals by maximizing the use of the land. This reduces the footprint of the developed area and allows forested or other natural areas to remain undisturbed.

Rainwater Harvesting

Utilize for Irrigation or Indoor Greywater

StormTrap offers rainwater harvesting applications that collect stormwater on site for use in irrigation or as greywater inside buildings.  These sustainable stormwater management practices adhere to low impact development (LID) principles for runoff reduction and also contribute to LEED (Leadership in Energy and Environmental Design) design credits for Sustainable Sites and Water Efficiency.

Recharge Groundwater and Reduce Stormwater Runoff

StormTrap offers infiltration applications for both the SingleTrap and DoubleTrap configurations. The StormTrap infiltration design provides a large infiltrative surface area that allows water to recharge back into the native soil, while preserving the land above for parks, roadways or parking lots. The infiltration system can also help meet low impact development (LID) goals by reducing the volume of stormwater runoff discharged from a site.


The SingleTrap and DoubleTrap design offers a wide range of options and benefits to deliver significant results for your project:

  • Designed to exceed HS-20 loading with minimum of 6″ cover
  • Made of reinforced, high-strength precast concrete available in internal heights that range from 1′ 1″ to 11′ 4”
  • Engineered to maximize storage volume while minimizing project footprint and cost
  • Meets stormwater regulatory requirements without compromising land use
  • Stone base foundation allows for groundwater recharge
  • Modular structures enable quick and efficient installation
  • Flexible design easily accommodates existing utilities, light pole foundations, trees and other job site constraints
  • Total void storage creates a fully accessible and maintainable system

Remove Pollutants and Achieve Flow Attenuation

Our StormTrap stormwater filtration process employs EPA-proven bioretention, vegetated filter strips and sand filters to remove pollutants and achieve flow attenuation. Our modular design makes it easy to incorporate these stormwater treatment methods with our stormwater detention and retention systems. We can even customize the stormwater quality features to target your specific issues.
