The 13-kilometre flood wall, built with help from the Royal Thai Air Force, would prevent water from outside from entering the site, said Chaturongkapon Sodmanee, the airport's general manager.
However, if flooding does occur inside the airport, it has 12 pumping stations with 37 pumps that have a combined capacity of pumping 48,000 cubic metres of water per hour.
The Royal Thai Air Force also has another six pumps with a capacity to discharge 26,000 cubic metres per hour.
As well, the airport also has an internal pond with capacity to accept up to 1.2 million cubic metres of water.
Mr Chaturongkapon said the airport had also prepared other equipment and machinery for any possible flood.
Under it management plan in case of a flood, the airport would close its entrances at ground level and create a new entrance linked to the elevated Don Muang Tollway.
Officials are confident that with such preparation, the airport will be able to provide services to passengers without any interruption.
The airport was hard hit during the great flood in October and November 2011 with water covering the ground and damaging many aircraft. Some had to be retired from service, abandoned or sold for scrap.
The great flood of 2011 left parts of the airport awash for weeks and damaged several aircraft beyond repair. (Bangkok Post File Photo)
