With heavy rain pelting the national capital through the day, the forecourt of IGI’s Terminal 3 as well as numerous roads and underpasses, many of which were near the airport, saw waterlogging.
An airport source said there had been a heavy spell within a short period, which led to the waterlogging, which was also captured on video and shared online. Pumps were deployed and the water receded within half an hour, officials said.

Responding to videos and complaints online, the Delhi Airport tweeted, “We regret the inconvenience caused. Due to sudden heavy rain, for a short period, there was waterlogging at the forecourt. Our team was immediately aligned to look into it and the issue has been resolved.”
In the evening, a DIAL spokesperson shed more light on what the issue had been: “Delhi has been witnessing record-breaking rains since last evening. This morning, due to sudden extremely high downpour, the forecourt of Terminal 3 of Delhi Airport saw some waterlogging, which cleared within a few minutes. The primary reason for rainwater moving towards Terminal 3 is the steep land gradient slope of about 17 metres between NH8 and Terminal 3. Due to this steep gradient, the entire area between NH8 and Terminal 3 acts as a catchment and drains water towards the terminal. This water is eventually carried by the city’s underground drainage system from Terminal 3 to Najafgarh drain. This drainage system from T3 to Najafgarh drain requires widening. DIAL has been working with state and central government bodies and officials for the past few years requesting to widen this underground drainage system. Several discussions in this matter have already taken place. We hope the drainage system would be widened soon.”
At least five flights had been diverted from Delhi; four of these flights — one from Kolkata and three from Mumbai — were diverted to Jaipur while a flight from Dubai was diverted to Ahmedabad. At least three domestic flights — Indigo flights to Lucknow, Indore and Hyderabad — were cancelled in the evening. Airlines too issued advisories stating that flight departures and arrivals are likely to be affected due to bad weather, and asked passengers to check the status online.
