Rain persisted all day, causing water to flood the road surfaces along the Rangsit Canal near the Red Bridge. Meanwhile, the municipality raised a red flag warning, closely monitoring the situation and informing the public about safe parking areas in case of severe flooding due to rising water.
At 14:30 on 25 Sep 2026 GMT+7, reporters reported a flood situation in Rangsit City Municipality near the Red Bridge embankment in Prachathipat Subdistrict, Thanyaburi District, Pathum Thani Province. The situation reached a critical stage after heavy, prolonged, localized rain caused water levels in the Rangsit Prayurasak Canal to rise rapidly, pushing up through drainage pipes and overflowing onto the road surface along the Rangsit Canal near the Red Bridge.
At 17:00, the Rangsit Prayurasak Canal near the Red Bridge was about 10 centimeters from overflowing its banks. Authorities were urgently placing concrete barriers over 300-400 meters as temporary water walls before installing pumps to draw water away from the Red Bridge community and reduce the impact on residents.
Police Captain Dr. Treelup Thupkrajang, Mayor of Rangsit City Municipality, took command on-site and coordinated personally. He revealed that water levels had risen rapidly due to prolonged rainfall, causing the warning level to escalate from yellow and orange to red, marking a concerning situation. However, compared to the past, the water management and improvements made have been more effective, so most communities have not been heavily affected except areas along the canal.
Police Captain Dr. Treelup added that he held meetings with the Director-General of the Royal Irrigation Department, the Pathum Thani Provincial Administrative Organization chief, and related agencies to expedite water drainage from the Rangsit Prayurasak Canal. Officials had installed additional barrier platforms and prepared to reinforce embankments in low-lying areas, anticipating more rain during this period.
Rangsit City Municipality urged residents to monitor the situation closely but remain calm. They arranged sandbag distribution points at Soi Rangsit-Nakhon Nayok 10 and coordinated safe parking locations for vehicles at Soi Rong Si, the 100 Years Building, Future Park shopping center, and behind Novotel Hotel (Rangsit Residence). Residents in flood-prone areas along the Rangsit Canal were advised to follow municipal alerts continuously to prepare for any further water level rises.
Meanwhile, Lam Luk Ka Subdistrict Municipality coordinated with the Royal Irrigation Department’s Khlong 13 drainage station to install 10 water pumps to speed water drainage from the area. They also requested opening the lower Gate 8 water discharge point at the Khlong Hok Wa intersection on the border between Pathum Thani and Bangkok to reduce flooding.
Initially, the Gate 8 lower water gate was raised about 20 centimeters because water levels on the Pathum Thani side were higher than Bangkok's side. This caused flooding along Khlong 8 in Lam Luk Ka, inundating homes near the canal at several points. The Lam Luk Ka Municipality rapidly prepared sandbags, water pumps, and flood prevention equipment to drain Khlong 7 and Khlong 8 into Khlong Hok Wa, fearing additional heavy rain in the evening. They appealed to the Royal Irrigation Department to raise the gate another 50 centimeters.
At the Rangsit Tai pumping station in Prachathipat Subdistrict, Thanyaburi District, Pathum Thani Province, Mr. Witthaya Kaewmee, Director-General of the Royal Irrigation Department, and his team visited to monitor the water situation. They convened all related agencies and accelerated operations by adding 13 more pumps to speed drainage into the Chao Phraya River. Continuous heavy rain in Pathum Thani had caused water accumulation and flooding in many areas, especially urban communities where drainage capacity is limited.
The Royal Irrigation Department instructed officials to monitor the water situation closely, manage water pumps and canal systems according to water volume and rainfall conditions, and expedite drainage from urban areas to minimize impacts on residents as quickly as possible.
