Rangsit Municipality maintains red flag warning as canal reaches 1.95m
Rangsit City Data Platform reported that the water level in the Rangsit Prayoonsak Canal reached 1.95 meters at the Blue Bridge in Prachatipat subdistrict, Thanyaburi district, Pathum Thani province, prompting municipal authorities to maintain a red flag warning on October 3, 2026, as multiple low-lying areas and riverside communities remained inundated. LINE TODAY reported the flooding conditions along the Rangsit-Nakhon Nayok road near มศว.องครักษ์, advising small vehicles to avoid the route.
Red Flag Warning Issued at Blue Bridge as Canal Level Reaches 1.95 Meters
The Rangsit Smart City urban development division at Rangsit Municipality used sensor systems at the Blue Bridge to track water heights, keeping the red flag active to signify the highest risk level for riverside zones. Rangsit Municipality urged residents in flood-prone districts to monitor real-time sensor data for travel planning and property protection. The persistent high water level in the primary canal network prevents secondary neighborhood drains from emptying effectively, keeping water trapped across residential zones.
Water stagnation has left deep pools inside housing estates where local depth reaches from calf to knee level, restricting motorcycles and small passenger cars. Residents rely heavily on pickup trucks and local assistance to get through flooded alleys.
Pump Capacity Concerns Raised During Pathum Thani Site Inspections
People’s Party leader Natthapong Ruangpanwut inspected the waterlogged neighborhoods in Pathum Thani alongside party members, distributing dried food, rice, and medical supplies to affected families. Natthapong questioned why local pumping operations functioned at only 60% capacity during the crisis, asking how long residents must wait for complete drainage. Disjointed agency responses compound the difficulty, prompting calls for centralized water release management across eastern Bangkok and Pathum Thani.
Pathum Thani Provincial Administrative Organization President Police Lieutenant General Kamronwit Thoopkrachang addressed reporters at Daily News, stating that the current inundation stems primarily from heavy rain bomb events rather than widespread regional overflow. Daily News reported Kamronwit's assurance that the situation differs significantly from the 2011 major floods, noting that current flows follow the main river channels rather than blanketing the region from all directions.
Municipal Officials Coordinate Drainage to Counter Upstream Flows
The Mayor of Rangsit explained that slow drainage occurs because the local canal system must ingest runoff from multiple directions simultaneously. Nation TV reported that municipal teams are pushing trapped water directly toward the Chao Phraya River to clear capacity for incoming northern water volumes. The ongoing coordination relies on continuous operation of sluice gates and heavy-duty drainage pumps positioned across Pathum Thani.
Data from previous heavy downpours between September 24 and September 26, 2026, overloaded municipal drainage capacity, pushing water tables above street levels across Thanyaburi and surrounding districts. Daily News noted that while provincial authorities maintain that the scale remains manageable compared to historic deluges, residents along the Chao Phraya River remain under close observation for combined threats from northern runoff, local cloudbursts, and high sea tides.
