BoreCharger, an innovative patented technique, is developed by Urdhvam, Pune that revives failed, dry and low yielding borewells by enhancing recharge multi fold . Summary of the model is as below:

• Borewells are drilled that tap deeper aquifer systems where natural percolation of rainwater doesn’t reach. Unregulated rapid pumping without any harvesting of rain water results into borewells going dry and failing eventually.
• There are no Economical and Sustainable solutions available to recharge borewells
• BoreCharger Technology introduced by this model improves recharge of borewells thereby improves borewell production capacity and in many cases quality of water as well.
• This unique and patent pending technology potentially converts all the borewells which can only abstract water into the borewells that can do both the functions of abstraction as well as recharge.

Socio-Economic Impacts

• Increases recharge of borewells 4 to 20 times than that of natural recharge
• BoreCharger induces artificial injection recharge of between 2 Lac to 80 Lac Litres of rainwater in the borewell every year
• 90% success rate in the revival of failed and low yielding borewells
• Improved irrigation and drinking water quantity and quality
• Reduced pumping energy costs and competition for water

The procedure of the BoreCharger technique is as below:

• Vital statistics about the borewell such as diameter, depth, casing type, casing depth, latitude, longitude, elevation, etc. is collected using a Mobile App.
• A trained hydrogeological expert, using a borewell underwater scanning camera system, undertakes a thorough hydrogeological investigation and lithological mapping. This provides information such as casing depth, any hindrances, depth of water-bearing structures, the thickness of aquifer structures, any deformities, caving ins, etc.
• Primary field observations of surrounding borewells and open wells coupled with secondary data available maps on geology and groundwater hydrogeology are studied to understand groundwater aquifer systems
• Information is also collected on the seasonal water yield behavior and historic information of borewell
• Based on this investigation the hydrogeologist decides where the BoreCharger tool should make precise perforations to the impervious borewell casing from inside at an appropriate depth.
• Water Quality test is carried out to provide valuable information to the client.
• The end customer is trained on the usage of the Borewell Inventory and Water Level Mobile App developed by Urdhvam to collect weekly/monthly data on seasonal water levels in the borewell.

• Increases water production capacity or yield of an existing borewell with very low investment
• Unique and Patented Technology that helps harvesting rainwater from unconfined aquifers and makes the borewell more sustainable by recharging the deeper aquifers
• We make this possible by a unique process which “perforates” existing borewell casing in-situ
• Our solution, by perforating the existing casing, “leaks” the unconfined aquifer water in the borewell and subsequently recharges the confined aquifer
• No civil construction, space and surface water source required
