Guwahati airport meets 28% of Terminal 2 water need from rain

Guwahati's Lokapriya Gopinath Bordoloi International Airport used harvested rainwater to meet 28% of the total water consumed at its new Terminal 2 in July 2025, the airport said on August 18. The airport has two rainwater collection tanks with a combined capacity of 1,000 kilolitres. The collected water is treated and used for drinking fountains, equipment cleaning and cooling towers.

Guwahati receives 1,800-2,200 mm of rain annually. Until August 9 this year, the airport recorded about 1,320 mm of rainfall. The airport treats the harvested rainwater through its water treatment plant, including advanced multi-stage purification for potable use.

The Adani Airport Holdings network runs the project, which it calls the first integrated rainwater harvesting initiative in its group. The airport aims to reduce dependence on external water sources by making rainwater a sustainable supply.
