Exlterra installs the first ever Energy-passive Groundwater Recharge system in Japan

We have successfully installed the first Energy-passive Groundwater Recharge system in Japan to address a standing water issue. The design has been oriented to work in relation to the surrounding geography, diffusing high concentrations of moisture equally through unsaturated soil layers; turning a flooded or muddy area into stable healthy soil.

Exlterra CTO Andrew Niemczyk discusses the installation process of the GEPS system with local drillers performing the installation.

The installation took place at a facility located in the Chiba Prefecture, approximately one hour away from Tokyo. On this site which is an open-air storage yard for a large construction group, the soil would become over saturated during rain events, leading to muddy terrain and pooling water that could last for more than a week. This is partly due to the geography of the surrounding area as well as the impermeable subsoil layers left behind in what was once a river bed.

Both our founder Andrew Niemczyk and CEO Frank Muller were on site to supervise the installation. During their trip, they had the opportunity to sit down and discuss the powerful system with potential partners, and further explore its many applications and benefits for Japan in the future.

The Exlterra Energy-passive Groundwater Recharge Product reduces surface flooding and creates a safer environment for both people and property alike. A major advantage of the system is that after installation, it continuously works to disperse soil moisture without the need of any power, maintenance, or replacement. Because the system is underground, it causes no disruption to everyday life taking place around it. This allows even the heaviest vehicles to drive over where it has been planted without risk of damage to the product or disruption to the systems capabilities.
