Bore Charger increases water production capacity or yield of an existing borewell with a very low investment. It is a unique technology which helps harvesting rainwater from the topmost, seasonally replenishable unconfined aquifers. Bore Charger makes the borewell highly sustainable by recharging the deeper confined aquifers. We make this possible by a unique patented process which “perforates” existing borewell casing from inside. This process potentially revives existing, failed and low yielding borewells. Setting up this borewell recharge system is extremely easy as it doesn’t require any civil construction, space and most importantly a surface water source.
