Bangkok Steps Up Drainage as Rain Eases, Flooding Improves
Bangkok is intensifying drainage operations as rainfall eases and water levels begin declining in eastern canals, though several areas including parts of the Saen Saep and Prawet Burirom canals remain flooded.
Bangkok Deputy Governor Vishnu Sriamsompol reported that the eastern side of the city continues to be affected by flooding, relying on the Saen Saep and Prawet Burirom canals as the main drainage routes to the Chao Phraya River. Authorities are operating pumps at full capacity as rainfall lightens and conditions gradually improve.
As of 18:30 on 27 September, Vishnu revealed that while several areas remain affected—particularly on Bangkok's east side—water levels in some canals have begun to decline, signaling an improving trend. The city is running full drainage operations and managing both primary and secondary canal systems, including the Bang Kak Saen reservoir tunnel, to push water toward the Chao Phraya River. Water levels in the Saen Saep canal have started dropping in certain areas such as Pherm Sin, allowing several roads to reopen and indicating progress in drainage efforts.
Vishnu noted that still-affected areas include sections along the Saen Saep canal from Khlong Tan through Thephlila, Bang Kapi, and Khlong Jan, as well as areas along the Prawet Burirom canal including Lad Krabang, Prawet, Suan Luang, Nakhon Kheela Village, and Khlong Hua Mak. Because water levels in the canals remain high, the city continues to manage levels gradually to drain water from streets and communities.
Petchburi Road's new section from Khlong Tan onward has improved with ongoing drainage, while Ramkhamhaeng Road still experiences flooding with close monitoring of the Saen Saep canal levels.
Bangkok is also managing water in the northern areas using the Premprecha, Ladprao, Bang Khen, and Bang Sue canals to absorb and divert water from surrounding areas, particularly along Vibhavadi Rangsit where some sections remain affected. The city is coordinating with relevant agencies to improve drainage efficiency.
With rainfall expected to lighten further and forecast amounts declining tomorrow, Bangkok will continue intensive drainage operations with water levels expected to gradually decrease. Deputy Governor Vishnu acknowledged residents' hardship in still-affected areas, especially the east side, and assured that all units remain working at full capacity to improve the situation. He urged residents to closely monitor updates from Bangkok authorities.
