Abstract

Facing severe water shortages in Kabul City, this study assessed the potential for recharging groundwater through rooftop rainwater harvesting at Kabul University, aiming to replenish groundwater and design a sustainable system. Methods included calculating rooftop area via Google Earth (128,641.02 m²), annual precipitation from NASA POWER (497.7 mm), GIS analysis to identify recharge well locations, and questionnaires administered to faculty and students. Findings indicate that 51,219.8 m³ of water could be collected annually; low-slope areas (0.001–0.388) are suitable for wells; and 91%–100% of participants supported the system. This research holds environmental, socio-economic, and water management value, establishing a scientific foundation for practical rainwater harvesting at Kabul University.
