Such is the situation that the operator has come up with a four-pronged strategy to stop rainwater from entering the terminal. The DIAL has also identified at least six spots where the sandbags need to be placed as soon as it rains.
“The entry of water in T3 after all the claims of being world-class was an embarrassing situation for DIAL. So even as work on the drain is on, this method has been zeroed in on to prevent the water from entering the terminal,” an airport source said.
After the flooding of June 16, a team of nearly 50 members was formed to stay at the airport round the clock. Their job is to start carrying sandbags on airport trolleys at the terminal gate as soon as it starts to rain. Sandbags will also be placed at the approach road just before the flyover.
“DIAL has also installed high discharge pumps at various locations to boost the discharge of standing water into the airport’s drainage systems. During this season, at all times, 30 dedicated personnel will be deployed on the T3 to manage the heavy flow of surface water,” said a DIAL spokesperson.
The IGI airport is located in a low-lying area compared to its catchment area. As a result, whenever there is heavy rain, the storm water runoff from nearby areas flows into the airport. Airport officials feel that once the modernisation work of existing drainage system is over, the problem will get solved.
