Groundwater is absolutely vital for sustaining over 80% of agricultural irrigation in India, underscoring its critical importance in food production. However, ensuring groundwater sustainability remains a pressing challenge, particularly in regions with hard rock, such as the Deccan basalts. Formed millions of years ago through volcanic eruptions, this terrain is characterized by complex geological formations with variable basaltic layer thicknesses, classified into two types: ‘simple’ and ‘compound’. Effective groundwater management in such settings requires integrated hydrogeological studies that rely on rainfall patterns, geological structures, and hydrographic data. To address these challenges, innovative approaches, such as BoreCharger, have been introduced. BoreCharger technology involves detailed hydrogeological investigations and perforation of borewell casings to enable recharge of deeper aquifers with freshwater from unconfined aquifers. This process enhances groundwater availability, improves quality, and revitalizes low-yielding or failing borewells, paving the way for sustainable water management. The present study, conducted at Khalad, Purandar, Maharashtra, demonstrates the positive outcomes of the BoreCharger application. Results show that BoreCharger-equipped borewells consistently sustain water levels until late March, ensuring a reliable supply for both agriculture and drinking purposes. Water quality has also shown significant improvement, with no adverse effects observed on groundwater levels or in nearby wells and water bodies. BoreCharger emerges as a powerful solution to combat the challenge of groundwater sustainability in basaltic terrains. Its ability to enhance both quantity and quality of groundwater highlights its potential for wider application beyond the study area.
