Department of Rapid Transit Systems

In order to ensure the safety of passengers and operations along with the sustainable operation of the MRT system, the flood prevention design elevation is based on a 200-year flood level plus 110 cm. In the event that flood prevention heights at exit/entrance are not achievable due to urban design or visual landscape considerations, the thresholds height of station exit/entrance is fixed at 60 cm and 100 cm flood gates are installed. In addition, waterproof doors capable of withstanding a 200-year flood level plus 110 cm of water pressure are installed beneath the exit/entrances.
