1
Rapid water absorption
Increases infiltration rate by up to 10 times, ensuring stormwater is absorbed into deeper soil layers quickly and effectively.
2
Flood and pooling prevention
Prevents surface pooling and reduces the risk of flooding by channeling excess water away from the surface, keeping landscapes usable.
3
Reduces soil erosion
Minimizes surface runoff and soil displacement, protecting landscapes from erosion and maintaining soil health over time.

How GEPS outperforms traditional stormwater management solutions
Feature | Exlterra | Traditional Solutions |
---|---|---|
Infiltration speed | Up to 10x faster, enabling rapid absorption | Slower absorption rates, leading to pooling |
Energy consumption | Requires no energy input, uses passive forces | Often depends on pumps or external power |
Erosion control | Naturally reduces surface runoff and erosion | Limited effect on erosion control |
Flood prevention | Quickly directs water into the ground | Surface pooling can lead to localized flooding |
Maintenance needs | Low to no maintenance required | Frequent maintenance to ensure functionality |
Landscape integration | Subsurface design preserves landscape integrity | Surface installations can disrupt aesthetics |
Long-term effectiveness | Durable, consistent performance over years | Often declines over time |
Exlterra GEPS design
The roots of soil health
Precision-engineered to use nature's forces
Exlterra’s GEPS units are designed to work with nature, using durable, chemically neutral polyethylene for long-lasting, eco-friendly performance.
Modular in design, they come in various lengths to address specific site needs with precision.
GEPS relies on a passive energy system that uses natural soil pressures to drive water infiltration, enhancing groundwater recharge without external power.
The compact, cylindrical units are installed 2 feet below the surface, blending seamlessly into the landscape without disturbing plants or infrastructure.
Built to withstand diverse ground conditions, GEPS offers a reliable, sustainable solution for water management and soil health.
Durable polyethylene build
Crafted from chemically inert polyethylene, GEPS units are long-lasting and resistant to environmental factors, ensuring durability in varied climates and soil conditions.
Modular design for flexibility
GEPS units come in multiple lengths, allowing tailored installation patterns that adapt to specific site requirements for optimal soil hydration and stability.
Passive energy activation
The unit’s internal structure harnesses natural soil forces, enabling energy-free water movement for efficient groundwater recharge and moisture control.
Compact profile for seamless installation
With a slim, cylindrical form, GEPS units install just below the surface, allowing integration into the landscape without disrupting existing vegetation or infrastructure.
Built for underground durability
Remain leak-free and effective throughout their entire lifespan.
Wide temperature range
Operates reliably from -20°F to 170°F (-29°C to 76°C)
Different lengths available
GEPS units range from 5 to 40 feet (1.5 to 12 meters) long.
Minimal installation depth
Installs just 1 to 1.64 feet (30 to 50 cm) below ground.
