On 19 March 2019, there were various alerts and videos reportedly stating that water had breached and entered a part of the MCE. Because the MCE is partially underground, some have speculated that seawater had entered the MCE and the MCE was not safe, while others speculated that a pipe had burst in the MCE.
While the fact of water entering the MCE is probably true, it is unclear if the water is seawater leakage or simply a burst pipe. We would like to highlight that the latter event had happened twice in the past – relating to burst pipes and sprinkler systems. There has not been an issue of a structural defect in the MCE leading to seawater leaking.

UPDATE:
This has been clarified – The Land Transport Authority has explained it to be an accidental triggering of the fire fighting sprinkler system.
Hence, the allegations are fake news.
