Bangkok: The Metropolitan Waterworks Authority (MWA) confirmed that the construction accident at the Min Buri water pumping station involved the construction of a clear water storage tank, not a water tunnel. The incident was triggered by the collapse of concrete reinforcement due to strong winds.
According to Thai News Agency, Mrs. Timaporn Wimonanupong, Assistant Governor (Engineering) and Acting Deputy Governor (Engineering) of MWA, revealed details from the construction supervisor's report. On July 6, 2025, at approximately 7:30 p.m., an accident occurred at the construction site of a 70,000 cubic meter clear water tank located at the Min Buri water pumping station on Nimit Mai Road. The accident involved the collapse of the concrete reinforcement prepared for the tank's wall. A strong gust of wind caused the temporary support structure to fail, resulting in injuries to 12 workers. Out of the injured, eight people sustained minor injuries and were able to return home immediately. Four individuals are currently under observation at Nawamin 9 Hospital. MWA has expressed its concern and support for the victims and their families.
The construction project, valued at 697.8 million baht, is being supervised by a consortium of consultants including Team Consulting Engineering and Management Public Company Limited, P and C Management Company Limited, and STS Engineering Consultant Company Limited. An investigation into the detailed cause of the accident is ongoing.
MWA has emphasized that the contract mandates the project supervisors and contractors to adhere to safety standards and maintain strict control over construction activities.
