Indira Gandhi International Airport in Delhi has achieved the distinction of becoming India’s first water-positive airport among facilities handling over 40 million passengers annually. This recognition reflects its ability to replenish more water than it consumes through advanced sustainability initiatives. The airport has installed 625 rainwater harvesting systems, two massive underground reservoirs with a combined storage capacity of 9 million litres, and a highly efficient 16.6 MLD zero-liquid-discharge sewage treatment plant. These efforts enable extensive recycling and reuse of water for operations such as irrigation, HVAC systems, and sanitation. By adopting smart systems and efficient infrastructure, IGI sets a national benchmark for sustainable airport management.
