Thonburi residents are suffering from excessive waste and mosquito infestations. Chatchawan is urging Bangkok authorities to urgently resolve sewage treatment issues as residents can no longer tolerate the foul water.
On 11 June 2026, Mr. Chatchawan Kongudom, a party-list Member of Parliament from the Ruam Thai Sang Chart Party (RTSC), raised concerns in a parliamentary session to highlight the public's distress caused by delays in the Bangkok Metropolitan Administration's (BMA) Thonburi sewage collection and treatment project.
Mr. Chatchawan stated that the project began in February 2022 and was scheduled for completion by 2025; however, many areas remain unfinished. This has led communities along canals in Bang Phlat, Bangkok Noi, and nearby districts to face problems with polluted water emitting foul odors, high mosquito populations, and immediate flooding during rainfall due to poor water flow and accumulated waste. Although the Drainage Department and district offices have occasionally sprayed mosquito repellent and collected garbage, these are only temporary relief measures rather than sustainable solutions addressing the root causes.
"I urge the Bangkok Metropolitan Administration, the Drainage Department, and related agencies to disclose detailed plans by canal and alley so residents can monitor progress, and to take concrete action to address the root causes of polluted water, waste accumulation, and mosquito breeding sites that transmit diseases. Continuous communication with the communities is also essential to quickly restore a good quality of life for the residents," Mr. Chatchawan said.
Furthermore, Mr. Chatchawan emphasized that the local people do not oppose the project, understanding its necessity for long-term sewage problem resolution. However, during ongoing construction delays, the BMA should implement more effective interim measures rather than leaving residents to bear unavoidable health impacts.
