KLIA PRIORITISES PASSENGER SAFETY AND CONTAINMENT MEASURES FOLLOWING WATER LEAKAGE AT KLIA TERMINAL 1

SEPANG - KLIA experienced a water leakage incident at Terminal 1 at 4.14 PM today following an episode of exceptionally heavy rainfall in the area, which coincided with an Aerodrome Warning issued by the Malaysian Meteorological Department (METMalaysia) for severe thunderstorms until 6.00 PM. 

Throughout the incident, KLIA’s focus remained firmly on passenger safety, containment of affected zones, and the protection of electrical systems. Airport teams were deployed immediately to secure impacted areas, guide passengers safely, and undertake precautionary power isolation where required. Containment, clean-up and restoration works were carried out promptly and continued more vigorously once weather conditions eased. 

Water in the affected sections was cleared within 1.5 hours, and check-in counters K and L have reopened after critical systems in the area were assessed and deemed safe for use. Core airport functions including passenger processing, terminal movement and key systems such as the Aerotrain and Baggage handling System were not affected. Technical checks are still ongoing and some support functions remain under close monitoring. 

KLIA has remained in close communication with its airline partners throughout to minimise any operational inconvenience. 

A technical assessment is underway to determine the root cause of the leakage, including contributing factors from the extreme weather experienced this afternoon. Any necessary corrective and preventive measures will be implemented to strengthen KLIA’s resilience against similar events.
