Recharge enhancement refers to methods used to increase the natural replenishment of groundwater supplies. This can involve techniques such as rainwater harvesting, where rainwater is collected and directed to recharge areas, or infiltration basins, which allow water to seep into the ground more effectively. These practices help improve water availability, especially in regions facing drought or over-extraction of groundwater. By enhancing the recharge process, communities can ensure a more sustainable water supply, benefiting both the environment and local populations.
