Water is essential for life, yet many regions around the world face severe water shortages. One key factor behind this crisis is the depletion of underground water sources known as aquifers. These natural reservoirs supply drinking water, support agriculture, and maintain ecosystems. Protecting and replenishing aquifers is critical to sustaining communities and the environment. New technology developed by Exlterra offers a promising way to restore aquifers naturally, helping to secure water for future generations. Natural wetland area showing water infiltration into soil Why Aquifers Matter More Than Ever Aquifers store vast amounts of freshwater beneath the earth’s surface. They act as natural sponges, holding water that can be drawn upon during dry periods. Around 30% of the world’s freshwater comes from groundwater, making aquifers a vital resource for billions of people. Unfortunately, many aquifers are being drained faster than they can refill. Over-pumping for agriculture, industry, and urban use lowers water tables, causing wells to dry up and land to sink. Climate change also reduces rainfall and disrupts natural recharge cycles. Without intervention, these trends threaten water security, food production, and ecosystem health. The Challenge of Natural Aquifer Recharge Aquifers recharge when rainwater or surface water slowly seeps through soil and rock layers. This process can take years or decades depending on the geology and climate. In many places, natural recharge is limited by: Urban development that covers soil with concrete, blocking water absorption Soil compaction from farming or construction reducing permeability Pollution contaminating recharge zones and groundwater Reduced rainfall due to changing weather patterns These factors mean aquifers cannot replenish quickly enough to keep pace with demand. Finding ways to enhance natural recharge is essential. How Exlterra’s Technology Supports Natural Recharge Exlterra has developed a technology that helps restore aquifers by improving how water infiltrates the ground. Their approach focuses on working with nature rather than against it. Key features include: Permeable surfaces that allow water to pass through instead of running off Engineered recharge basins designed to maximize water absorption Soil conditioning to increase porosity and water retention Monitoring systems to track recharge rates and water quality By combining these elements, Exlterra’s technology accelerates the natural process of aquifer replenishment. This method reduces flooding risks, improves groundwater levels, and supports sustainable water use. Real-World Examples of Aquifer Recharge in Action Several projects using similar natural recharge techniques demonstrate the potential impact: In California’s Central Valley, recharge basins capture excess winter runoff and direct it into underground aquifers. This practice has helped raise groundwater levels by several feet in some areas. In Australia, permeable pavements and rain gardens in urban neighborhoods allow stormwater to soak into the soil, reducing pressure on local aquifers. In India, traditional water harvesting structures combined with modern soil treatments have restored groundwater in drought-prone regions. These examples show how targeted interventions can make a measurable difference in aquifer health. Benefits Beyond Water Supply Enhancing natural aquifer recharge offers multiple advantages: Improved water quality as soil filters pollutants during infiltration Reduced surface flooding by capturing stormwater on site Stronger ecosystems supported by stable groundwater levels Lower energy use compared to pumping and treating surface water Resilience to drought through increased water storage underground Communities that adopt these methods gain long-term water security and environmental benefits. What You Can Do to Help Recharge Aquifers Individuals, businesses, and governments all have roles to play in protecting groundwater: Support policies that protect recharge zones from development and pollution Use landscaping techniques that promote water infiltration, such as rain gardens and permeable driveways Reduce water waste and adopt efficient irrigation methods Invest in or advocate for projects that restore natural water cycles Educate others about the importance of groundwater and recharge Every action contributes to healthier aquifers and a more sustainable water future. Looking Ahead: The Future of Aquifer Recharge Technology As water challenges grow, technologies like Exlterra’s will become increasingly important. Continued research and innovation can improve recharge methods, making them more effective and affordable. Integrating these solutions into urban planning and agriculture will help balance water use with natural replenishment. Collaboration between scientists, engineers, policymakers, and communities will drive progress. By valuing groundwater as a precious resource and investing in its renewal, society can avoid severe water shortages and protect ecosystems.

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. Two Key Installations, One Shared Problem We have recently completed GEPS installations in two very different contexts: Denver, Colorado  – on the premises of the Owens Corning roofing plant. Elevation:  Denver sits at approximately  5,280 ft above sea level. The detention pond at this site was frequently overflowing onto a road used by delivery trucks, disrupting operations and posing safety risks. Salisbury, Maryland  – within a 65,000-gallon detention pond on the premises of the  Maryland Department of Transportation, Motor Vehicle Administration (MVA) . Elevation:  Salisbury is nearly at  sea level , around  36 ft  above sea level. Despite being intended as a detention pond (not retention), water frequently stood there, defeating its purpose. The Challenge: Standing Water in Detention Ponds Both ponds suffer from the same issue: water remains stagnant long after rain, even though they were designed to drain. This persistent standing water can lead to: Mosquito breeding and associated health risks Odor problems Disruption to site operations (as seen in Denver) Regulatory risk and poor stormwater management Traditional fixes like pumps are expensive, energy-intensive, and require maintenance. GEPS offers a smarter, passive alternative. GEPS to the Rescue: How It Works GEPS is installed below the surface, without moving parts or electricity. Its key benefits for these detention ponds include: Faster Recovery After Storms:  Following a rain event, the ponds drain more quickly, minimizing downtime and overflow risk. Long-Term Reduction in Standing Water:  Over time, GEPS helps maintain lower average water levels — significantly reducing stagnant water periods. Passive, Sustainable Solution:  Unlike pumps, GEPS works with the natural subsurface to manage water, requiring no ongoing energy input. Real-World Impact In  Denver , GEPS helps avoid overflow on the plant’s access road — a major operational benefit. In  Salisbury , through subsurface infiltration and balanced redistribution, GEPS offers the only viable, low-impact solution (besides pumping) for managing the full 65,000-gallon capacity — particularly crucial given its extremely low elevation. A Model for Smarter Infrastructure These installations exemplify how GEPS can convert underperforming detention systems into efficient, environmentally sound assets. By retrofitting failing ponds, Exlterra is helping organizations like Owens Corning and the Maryland Department of Transportation: Reduce risk and liability. Cut down on maintenance and energy costs. Improve resilience and sustainability in stormwater management. Interested? Learn more or find a licensed installer near you today!

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. What Stops Water from Soaking into Soil? Clay and Dense Soils Clay-rich and other dense soils have very small particles that fit tightly together. This leaves little space for water to move, and once water gets in, it’s placed under so much pressure it gets trapped. When clay soil is dry, it cracks, but once it gets wet, those cracks close and water can’t get through. Compacted soils, which happen when soil is pressed down by heavy equipment or foot traffic, have the same problem. The soil gets squeezed, the spaces between particles shrink, and water stays on the surface or gets trapped inside instead of moving further. Surface Crusting During dry months, the very top of the soil dries out and forms a "crust" that makes it difficult for water to infiltrate. Since GEPS rebalances moisture content in the soil year-round, the ground where it's installed won't form a "crust" in dry months, and will accept water much quicker during rain. Capillary Barriers Between Soil Layers Many soils have layers with different textures. For example, a fine clay layer might sit on top of a sandier layer. Water moves down through the fine layer but then stops at the boundary with the coarse layer - even though coarse soils tend to infiltrate better on their own. This happens because water needs more force to move from the smaller spaces in the clay layer into the bigger spaces in the sandy layer. The result is water "pooling" above the boundary, causing soggy soil above and dry soil below. Low Organic Matter and Poor Structure Soils with little organic matter or few plant roots have fewer large pores. Without these natural channels, water moves slowly or not at all. Poor soil structure can also result from erosion or lack of biological activity. How GEPS Can Help GEPS Passively Infiltrates Water GEPS doesn't act like a straw or a pipe - it creates pressure gradients in the soil that help water move where it naturally wants to move, through the soil itself. As the soil expands and contracts with wetting and drying cycles, GEPS will squeeze and relax, encouraging water to move where it's meant to go - from areas of high to low concentration. GEPS Resolves Capillary Barriers At the boundary between different soil layers, the pressure gradients created through GEPS help water cross from one layer to the next. Improves Soil Structure Over Time As GEPS works, it responds to the soil expanding or contracting around it, agitating the soil. This means that over time, water can move more freely, and the soil becomes healthier and more stable overall. This also solves issues related to low roots/organic matter, since healthier soils mean stronger turf and vegetation. No Power or Maintenance Needed GEPS works through the natural movement and behavior of soil and water. It doesn’t need electricity or regular maintenance. Once installed, it keeps working on its own as a true set-and-forget environmental solution. Why GEPS is the best-in-class solution for improving your soils Poor infiltration is a common problem caused by clay soils, surface crusting, capillary barriers, and low organic matter. GEPS solves these problems by creating new opportunities for water to infiltrate, breaking through tough soil layers, and improving soil structure. It’s a simple, long-lasting solution for better water management and healthier soil. GEPS can... Reduce runoff and erosion by letting more water soak in Prevent water pooling and soggy spots in clay or compacted soils Help plants grow by making water available consistently in the soil Improve stormwater management and groundwater recharge ...All completely passively, in the healthiest long-term method for your ground.

The Groundwater Energy Passive System (GEPS) by Exlterra is revolutionizing water management in turf and landscape environments, especially on golf courses. By enhancing soil-water interactions, GEPS delivers measurable improvements in water conservation, moisture retention, and sustainability - directly supporting environmental goals and significantly reducing the need and cost of irrigation. GEPS and Water Conservation GEPS is engineered to optimize the natural movement and retention of water within the soil. Their unique design: Expands the capillary fringe , allowing water to be retained and distributed more efficiently throughout the soil profile. Resolves hydraulic discontinuities , breaking through compacted or layered soils that typically restrict water movement. Increases the soil’s capacity to store and retain moisture , even after rainfall or irrigation events. These enhancements are achieved passively, requiring no external power or maintenance, making GEPS a sustainable, long-term solution for water management. Real-World Impact: Reduced Irrigation on Golf Courses Golf courses across diverse climates and geographies have reported dramatic reductions in irrigation needs after installing GEPS. Based on field data: Irrigation requirements are reduced by 30-60% , depending on the region, climate, and specific area of the course. Fairways, which traditionally require more water due to their larger surface area and exposure, see the greatest decreases in irrigation, often on the higher end of the reduction range. Greens, with their specialized turf and soil composition will also benefit, though the percentage reduction is typically somewhat lower than fairways. This reduction is achieved without compromising turf quality or playability , and in many cases, turf health and resilience actually improve due to more consistent soil moisture levels. Sustainability and Environmental Benefits The environmental advantages of GEPS extend far beyond water savings: Supports Sustainability Goals: By reducing water consumption, GEPS helps golf courses and other managed landscapes meet regulatory and voluntary sustainability targets. Lowers Operational Costs: Less irrigation means lower water bills, reduced energy use for pumping, and less wear on irrigation infrastructure. Reduces Runoff and Erosion: Improved water retention decreases surface runoff, helping prevent erosion and protecting local waterways from nutrient and chemical leaching. Promotes Healthier Soil and Turf: Enhanced moisture retention supports robust root systems and healthier plant growth, reducing the need for supplemental fertilizers and chemicals. Why GEPS is the Future of Water Management Traditional irrigation methods often result in uneven water distribution and excessive water loss through evaporation or runoff. GEPS addresses these challenges by: Creating a more uniform and stable moisture profile in the soil. Allowing rain and irrigation water to penetrate deeper and be retained longer . Reducing the frequency and volume of supplemental irrigation required. By leveraging advanced soil science and innovative engineering, GEPS provides a passive, maintenance-free solution that aligns with the growing demand for sustainable, cost-effective water management in the turf industry.

Urban stormwater management faces critical challenges as cities expand, but Exlterra’s Groundwater Energy Passive System (GEPS) offers an innovative solution. This technology maximizes infiltration in space-constrained environments while ensuring environmental safety and can be used standalone or alongside existing low-impact development (LID) systems. How GEPS Maximizes Infiltration in Tight Spaces GEPS leverages volumetric distribution to overcome surface area limitations. When stormwater enters a soil volume where GEPS is present, it passively and naturally flows underground in all three axes of physical space (vertical and lateral) and is dispersed across a vastly expanded soil footprint. A single 40-foot GEPS unit can redistribute water across 8,495 sq. ft of soil beneath the ground. This approach ensures efficient water absorption even in dense urban settings, where traditional stormwater solutions typically require larger footprints. GEPS as a standalone Low Impact Development technology GEPS follows the principles of Low Impact Development (LID) by virtue of its design, installation, and effects: GEPS is a completely passive technology that leverages the natural behaviors and properties of soil and water to boost their interaction. GEPS minimizes the impact of ground compaction and runoff generated by impervious surfaces by enhancing the infiltration rate of soils and giving water more space in the ground to distribute. GEPS manages stormwater at the source instead of moving it elsewhere. GEPS is installed without the need for excavation or other invasive processes, and spaces where GEPS has been installed are usable as soon as work is complete. GEPS can be implemented in microscale projects where space is limited, or scaled up to cover large areas. GEPS is maintenance-free as a passive technology, and does not require any power or other infrastructure to bring its benefits to a project. Additionally, GEPS has no negative environmental impact : Studies have shown that even with a stormwater infiltration rate increase of up to 10.2x , GEPS does not accelerate the movement of contaminants within a soil volume. Studies tracking the levels of both chemical and microbial contaminants (chlorides and E.Coli) showed no impact on their levels within the groundwater, even as GEPS decreased the runoff load to existing stormwater systems by 80%. GEPS as a supporting Low Impact Development Technology Existing stormwater LID solutions can be significantly improved by introducing GEPS into a project. Better infiltration rates and increased stormwater storage capacity in the underground soil volume can help existing solutions achieve better performance , remediate failed solutions , or even allow solutions to be implemented in situations that wouldn't gain approval otherwise.
