Floodwater in Bangkok’s Rom Klao and Lat Krabang areas has fallen by 50cm after sustained pumping, Governor Chadchart Sittipunt said on Sunday, October 4, 2026. Bangkok authorities are preparing recovery work, with conditions expected to improve substantially on Monday.
Chadchart said vehicles could now enter and leave an evacuation centre in the flood-hit Rom Klao and Lat Krabang area following continuous efforts to pump out water.
Water levels in Bangkok’s main canals had generally improved, Chadchart said, with the exception of Prawet Burirom Canal. Drainage through the canal remained a concern for Rom Klao, Lat Krabang and Saphan Sung, where water needed to be discharged more quickly.
The Bangkok Metropolitan Administration (BMA) would immediately deploy pumping equipment to housing estates where floodwater was struggling to drain, Chadchart said.
Bangkok authorities have divided recovery work at Rom Klao Housing Estate into four zones, Chadchart said. Different agencies would share responsibility to ensure assistance reaches the whole estate.
Chadchart said the area free of floodwater at Rom Klao Housing Estate was expected to increase by 80% on Monday, October 5. Parts of the estate, which covers more than 2,000 rai, had already begun to dry out on Sunday, but the entire site could not be drained at once, he explained.
At Khlong Chan Housing Estate, where floodwater had receded, the BMA was working with the Defence Ministry on a plan to accelerate the removal of large quantities of rubbish, Chadchart said. The aim was to restore normal conditions as quickly as possible.
Bangkok had lowered water levels in advance as much as possible to prepare for rain expected over the next one or two days, Chadchart said in his Sunday update. He cited a Thai Meteorological Department forecast of around 30mm of rain.
Chadchart said the additional rainfall would not be a major concern compared with the previous week, provided it did not linger over the same areas and accumulate for an extended period.
Chadchart was confident the previous week’s flooding would not be repeated, describing the incoming rain as typical monsoon weather rather than another prolonged downpour. The earlier spell had brought accumulated rainfall of 300mm over three continuous days, he said.
Roads could still struggle to drain after only half an hour of rain because canals remained close to full and the ground was saturated, Chadchart explained. The saturated ground could not immediately absorb additional water.
Upstream runoff and tidal water entering the Chao Phraya River were not currently causing problems for Bangkok, Chadchart said. The city’s flood barriers still had substantial capacity to cope with higher water levels.
Chadchart also cited the Thai Meteorological Department’s assessment that upstream water volumes were within manageable limits and urged residents to ease their concerns.
