Abstract : Rapid urbanization has placed unprecedented stress on groundwater resources, leading to declining water tables, deteriorating water quality, and long-term sustainability concerns in cities. Artificial recharge techniques, which include engineered and natural approaches for replenishing aquifers, have emerged as a viable solution for sustainable groundwater management. This paper explores the application of artificial recharge methods for groundwater conservation in urban areas. It discusses the principles of recharge, the variety of techniques employed such as recharge wells, percolation tanks, recharge trenches, and rainwater harvesting systems, and their integration into urban water management frameworks. The study also highlights challenges related to site selection, clogging, pollution risks, and governance issues. Case studies from Indian and global cities are presented to demonstrate effectiveness. Moreover, a comparative analysis of recharge techniques is given to evaluate their cost-effectiveness, efficiency, and environmental impact.
