Bangkok Deploys Targeted Pump Strategy to Aid Flooded Communities

Bangkok Governor Chadchart Sittipunt said the city is preparing a more targeted pumping operation, potentially seeking private-sector support and deploying large Phraya Naga pumps to drain flooded communities. Speaking at Bangkok's Flood Prevention System Control Centre on Tuesday, Chadchart, joined by deputy governors Wisanu Sapsompol and Sanon Wangsrangboon, said no additional rain had fallen and water levels in affected communities were gradually receding.

"We only know today's rain forecast. We cannot forecast as far as the day after tomorrow; we have to look at the overall picture," Chadchart said. "For now, it remains dry and there has been no additional rain."

The main areas of concern remain Ramkhamhaeng, Bueng Kum, Seri Thai, Nawamin, Lat Krabang and Luang Phaeng, where flooding persists but water levels are gradually falling. Food distribution at Khlong Chan flats has been adjusted to ensure aid is distributed more evenly based on each community's needs.

"There are 30 flats at Khlong Chan, as well as other buildings in the area, including around Lat Phrao 120. Everything is now in the system," he said. "We know how many boxed meals are needed. If district offices cannot provide enough, central authorities will send supplies produced by the Bangkok Metropolitan Administration's Education Department, with community representatives collecting the meals."

Earlier assistance had not always reached everyone because boats delivered aid first to the communities they encountered. Authorities are now accelerating help for deeper-lying condominium communities and housing estates. Some areas were already improving; residents of Chinnakhet Village, who needed food deliveries on 28 September, no longer need them because they can walk out to buy food at markets.

"As water levels begin to fall, demand will adjust to the real situation. Remaining resources can then be concentrated on other areas," Chadchart said.

The current flooding covers a wide area and requires support from multiple agencies, including boats and vehicles. Previous floods had often been more localized, but the scale of the latest heavy rain means the BMA needs wider cooperation. Chadchart expects water levels to fall more quickly over the next two days and said the BMA would accelerate pumping operations.

"The next thing we need more of is pumping water out of communities. We are preparing a plan and may seek cooperation from several agencies, including private companies that may have large Phraya Naga pumps," he said.

Previously, pumping operations focused on moving water from canals into the Chao Phraya River. The next phase could involve a more targeted, guerrilla-style operation using submersible pumps and large pumps in specific villages and communities. If capacity exists outside flooded areas, such as lower canal levels, pumps can be mobilized accordingly.
