Groundwater Energy-Passive System
WHAT IS GEPS?
GEPS, or the Groundwater Energy-Passive System, is an innovative solution for stormwater management that uses the natural properties of soil to enhance water infiltration and storage. Acting like an artificial root system, GEPS units—ranging from 2 to 40 feet in length—are strategically installed below the surface to create an effective water distribution network. These impeller-shaped units are designed to cause minimal disruption to the site during installation, enabling water to move through and into various soil layers. By improving soil permeability and preventing hydrostatic buildup, GEPS offers a long-lasting, eco-friendly solution that helps soils absorb water up to ten times faster than traditional methods, without any energy consumption or ongoing maintenance requirements.
HOW DOES GEPS WORK?
GEPS works by taking advantage of natural soil movements. When placed into drilled holes, the GEPS units form a network beneath the topsoil, where soil expansion and contraction activate the system, creating a passive pumping action that moves water efficiently. Each unit punctures soil layers, breaking hydrostatic pressure and enabling water to disperse more easily, which reduces water buildup between layers and promotes faster infiltration. Once surface water enters the GEPS system, it is naturally distributed through soil capillary action, allowing water to reach even deeper soil levels. This process not only prepares the soil for future rain events but also provides an energy-free, low-impact method to manage and utilize stormwater effectively.
ENHANCING GREEN INFRASTRUCTURE
Imagine getting more from your Green Infrastructure without expanding the surface area. With GEPS, you can increase your existing infiltration rate by up to 10 times while storing more water in the in-situ soils below your stormwater control measure getting more for your investment.
IMPROVING STORMWATER PONDS
Whether looking to get more out of a surface detention pond or maximize an underground detention systems volume, GEPS unique way of pulling water into the strata of underlying soils quadruples the volume for a half the price by volume of traditional stormwater detention systems.
ELIMINATING PONDING WATER
If you have nuisance water that simply wont drain, GEPS offers a non-intrusive method to solve ponding water issues. Whether it’s a stormwater control measure that’s lost its ability to infiltrate or a low spot that’s settled, GEPS can restore and improve long term infiltration rates with minimal site disturbance.
THE BENEFITS
- Infiltrate standing water
- Increase infiltration rates 5-10x
- Reduce runoff water and downstream flooding
- Stabilize soil moisture content
- Recharge groundwater
- Manage surface water
- Eco-friendly
- 0$ maintenance requirements
- Easy to install with little ground disturbance
STRONGER TOGETHER
The total volume of water to be infiltrated by the GEPS can be enhanced by pairing it with other common stormwater water practices that capture peak stormwater volumes. GEPS works well with ponds, bioretention systems, and other subsurface storage systems. This “systems approach” captures stormwater runoff, stores the peak volume, adsorbs certain pollutants of concern, and allows large volumes of water to infiltrate over time.
