Bangkok:Relief is finally in sight for residents in eastern Bangkok as high-capacity, custom-built pumps have successfully drained major floodwaters from the Klong Chan National Housing estate. These pumps, known locally as "Tho Sing," were originally developed from agricultural water pumps.
According to Thai News Agency, water levels at the complex have dropped by more than a meter, leaving only shallow pockets of water measuring 20 to 30 centimeters in some areas. This reduction has allowed residents to walk through their neighborhood once more. However, as the water recedes, the extent of the damage is becoming evident, with residents inspecting ruined belongings and submerged vehicles. While basic running water services have been restored, clean drinking water remains scarce, and the stench of stagnant floodwater persists.
The rapid drainage was achieved using four 15-inch agricultural pumps that were modified for urban use, efficiently discharging the floodwaters into the nearby Saen Saep Canal. Attapol Noomsamlee, owner of the high-speed "Tho Sing" pump, explained how the equipment evolved from small pumps for paddy fields into mobile units with mounted engines and drive systems.
The Bangkok Metropolitan Administration (BMA) supported the operation by accelerating water flow along the main canal to lower overall water levels and prevent backflow. Bangkok Governor Chadchart Sittipunt emphasized the effectiveness of these modified agricultural pumps, noting their suitability for low-lying, basin-like areas such as housing projects. He expressed gratitude to volunteers from Prachinburi and Ayutthaya, the Royal Irrigation Department, and the private sector for their assistance, and suggested that these pumps might be added to the city's inventory for future use.
With conditions improving at Klong Chan, officials plan to clear the remaining low-lying pockets before redeploying the "Tho Sing" pumps to other affected areas in eastern Bangkok, including the Kheha Romklao estate in Lat Krabang.
