- More areas at risk due to lack of organisation
With the city centre, Suvarnabhumi airport and two industrial estates at risk, officials have been racing against the clock to drain water out of the eastern part of Bangkok through the city's canal system.
However, a lack of coordination between water management officials at both the city and national level has probably put more areas in danger.
In a worst-case scenario, the only option to solve the crisis would be to let the water drain through floodways _ which are not regulated by gates or pumps _ resulting in no control over the flow.
"Water drainage via floodways is something people on the job don't want to talk about," said Sutat Weesakul, a member of the Water Drainage in Disaster Areas Committee.
"They all know that by draining water via floodways, people downstream could be at high risk of being flooded."
The eastern side of Bangkok, home to Suvarnabhumi airport and the Bang Chan and Lad Krabang industrial estates, is a major concern for business, politicians and officials.
