Surat District faces critical groundwater challenges, including high salinity, nitrate contamination, and seasonal depletion. Using the National Aquifer Mapping and Management (NAQUIM) Report as a baseline, this study projects future degradation of aquifers over the next 20 years if no intervention is implemented. The Global Rainwater Management Program (GRMP) offers comprehensive solutions tailored to each taluka through 11 innovative techniques, including artificial wetlands-based recharge systems and a proposed district-wide 1 CBM Canal network. The success of GRMP implementation in Kavas village exemplifies the program’s potential. This research paper provides taluka-wise groundwater conditions, the effectiveness of GRMP solutions, and a 20-year comparative analysis between intervention and non-intervention scenarios. GRMP is further proposed as a solution addressing not only groundwater quality and quantity but also climate resilience, economic sustainability, and ecosystem preservation.
