Impact & Risks

The incomplete drainage system poses risks of flight delays, diversions, and cancellations during heavy rains. Passengers may face difficulties accessing vehicles due to waterlogged areas. Aircraft operations, including parking and runway usage, are vulnerable to disruptions. Temporary closures of the airport during intense rainfall remain a possibility until the drainage project is completed. The situation highlights the need for urgent completion of infrastructure to mitigate risks during the monsoon season.
