Delhi Airport Becomes India's First 'Water-Positive' Airport
Indira Gandhi International Airport (IGI), in December 2025, achieved a major sustainability milestone, became India's first airport with over 40 million passengers to be certified as 'water-positive'.
A water-positive facility is one that replenishes more water than it consumes—a distinction IGI earned through a combination of innovative infrastructure and water management practices.
The airport now boasts 625 rainwater harvesting structures, two newly constructed underground reservoirs with a total capacity of 9 million litres, and a 16.6 million litre per day (MLD) zero-liquid-discharge sewage treatment plant. These systems allow IGI to capture, store, and recycle water for multiple non-potable purposes.
