A joint inspection ordered after alleged reverse flow from drains led to waterlogging inside Terminal 3 of IGI Airport on Sunday, resulted in a blamegame as Public Works Department (PWD) claimed that the drainage system was not faulty and the water entered the airport premises since it is on a low-lying area.
The Delhi International Airport Limited (DIAL) had earlier said the clogged drains around the airport compound led to rain water back-flowing into Terminal 3.
The inspection was undertaken by PWD and DIAL.
The PWD also claimed that the internal drainage system of the airport was unable to handle the water. It has asked DIAL to submit the internal drainage drawings.
“We have agreed to improve the diversion of stormwater from Rangpuri and Mahipalpur in the newly constructed drain, but what needs to be understood is that water is flowing along the road from Radisson Hotel and through the loop at NH-8, and DIAL needs to tap it. The airport is located in a low-lying area and water will enter the compound. They need to ensure that a proper drainage system is in place inside the airport to deal with water flow,’’ a senior PWD official said.
DIAL declined to comment on this issue.
“On our part, we have built a drain on the periphery of the airport. It begins from Rewari railway tracks and goes up to the Najafgarh drain. But this drain cannot take the water entering the airport as the internal drains in the airport compound will have to take in the flow. These internal drains are connected to the drainage on the periphery,’’ the PWD official said.
According to PWD, the Dwarka underpass has been getting flooded lately as Aerocity has blocked the area that used to absorb the water flowing from Mahipalpur to Shankar Vihar. “We will now have to extend our drainage on the periphery from Mahipalpur to Shankar Vihar. This work is already going on and is expected to be completed by July 15,’’ an official said.
On Sunday, heavy rainfall affected the services at domestic arrivals of Terminal 3. Airport authorities had to shut down four baggage belts.
