The flooding in inner Bangkok was caused by the sudden deluge of more than 100 millimetres of rain, well above the city's drainage capacity which could handle up to 60mm of rainfall at a time, Bangkok deputy governor Wallop Suwandee said on Wednesday.

He said the city’s drainage system - including water gates, pumping stations and water tunnels - had functioned efficiently.

The BMA had now cleaned out 97% of the city's drains and reduced water levels in canals in preparation for more rain.

The population of Bangkok has quadrupled in the last two decades, but its drainage and sewers stay the same. Add this to the slow sinking of the city and these types of floods are inevitable.

Even during the dry season the drainage system of Bangkok was already half full (or half empty, depending on who said it).
