GEPS® reframes the entire relationship between a resident's stormwater complaint and what a municipality can offer in response. Instead of telling a homeowner that the system cannot accept their water, municipalities can point to a solution that resolves the problem on-site, without adding a single gallon to the storm sewer system.

A passive, maintenance-free technology from Exlterra called the Groundwater Energy Passive System (GEPS®), addresses both of solar's major soil-related headaches: stormwater runoff driven by construction compaction and decreased permeable surface area, and long-term structural damage caused by uneven moisture distribution around panel footings.

If you've ever noticed cracks snaking across a basement wall, doors that suddenly won't close right, or a driveway that's heaved up in the middle of nowhere, you may have experienced one of the most costly and least-talked-about problems in construction: expansive clay heave. It's a problem that quietly destroys billions of dollars in homes, commercial buildings, and infrastructure every year.

At Exlterra, we’re proud to be applying GEPS (Groundwater Energy Passive System) to solve real, persistent challenges in stormwater infrastructure — not just on golf courses, but in critical detention ponds that struggle with standing water.

Golf courses worldwide are facing increasing challenges related to water conservation, climate extremes, and the need for sustainable outdoor spaces. The Royal Antwerp Golf Club (RAGC), Belgium’s oldest club known for preserving and nurturing its heritage courses, has once again raised the bar – this time, as the first golf course in Belgium to install Exlterra's GEPS (Groundwater Energy Passive System).

Water needs to move through soil for healthy plants, stable foundations, and effective stormwater management. But in many places, water can’t get into the soil volume as it should. This is usually due to the type of soil, how the soil is arranged, or the way different soil layers interact. Below, we explain the main reasons why soil infiltration is often poor and how Exlterra's Groundwater Energy Passive System (GEPS) can help.
