Resolving Municipal Stormwater Issues with GEPS®
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.

Protecting Solar Investments from the Ground Up with GEPS®
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.

The Ground Beneath Your Feet Is Moving — And GEPS Is Here to Help
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.

Overcoming Soil Infiltration Barriers: How GEPS Solves the Problem
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.
