Safe, reliable, and cost-effective groundwater measures!!

Eco Recharge (circular groundwater level control method) is a technique aimed at preventing the decline of groundwater levels by efficiently recharging aquifers. This is achieved by pumping groundwater from extraction wells and pressurizing it to inject into the ground through injection wells. Groundwater extracted from wells such as deep wells is sent to a sand separator, where impurities like sand contained in the water are removed. The treated water is then sent to a receiving tank, and through a system that integrates measurement and control, it is recharged into the ground via injection wells to control the groundwater level.

basic information

<Environmental Conservation> By adjusting the amount of water injected, we control the groundwater level and prevent the lowering of water levels in the surrounding area, thereby preventing well depletion and ground subsidence. <Economic Efficiency> Due to efficient water recovery through pressurized injection, there is no surplus water generated, and no treatment costs for sewage systems arise. The pressurized injection allows for high water injection capacity, reducing the number of injection wells needed. The use of small-diameter pipes (approximately φ50mm) for injection wells results in lower installation costs. <Safety> Using an integrated system for water level measurement and control of the injection amount allows for immediate response to sudden changes in groundwater levels, ensuring that the groundwater level is consistently maintained.
