Water outage in Bangkok: pipe repair near Kiakkai on November 12

A water outage in Bangkok near Kiakkai is possible at night on November 12, 2026, after damage to the water main on Thahan Street repairs were scheduled, which may reduce water pressure or temporarily cut off supply in some neighborhoods, but not across the entire capital. According to reports from the road service and a radio station, a temporary suspension of water supply has been announced for the period from 22:00 on November 12 to 05:00 the next day; the actual time when supply and pressure will be restored has not been confirmed. The Dusit district administration recommended through local media that residents of affected buildings stock up on water by 20:00 on November 12, before the announced night work begins.

What is known about water pipe damage near Kiakkai

According to a report by Matichon, on November 11 a contractor building a bridge across the Chao Phraya River damaged a pipe at the entrance to army housing blocks. The incident site is between the Kiakkai intersection and the Saphan Daeng intersection: water spilled across the road, and for some residents the pressure dropped or the supply was cut off.

The damaged pipe with a diameter of 600 mm was covered with a steel plate and welded shut, but the seam kept leaking. Water supply was restored around 06:00, but a repeat repair was needed.

Water outage in Bangkok: nighttime repair schedule

We previously wrote about other nighttime work on Bangkok’s water supply system · RU; that is a separate event, and its schedule does not relate to the current pipe damage.

As Matichon reported, additional welding work on the damaged section was scheduled for around 22:00. The city’s road alert service clarified that this concerns urgent repairs to the main near Bangkrabue Canal, while a radio station announced a temporary suspension of water supply from 22:00 on November 12 to 05:00 the next day.

This time should be understood as the announced window for a temporary suspension of water supply, not a promise that pressure will be restored everywhere by 05:00. The Dusit district administration’s warning about a possible supply cut was a precautionary measure, not confirmation that water had already been shut off in every building.

Residents were advised to prepare water by 20:00 on November 12 — this deadline does not match the start of the repairs.

Where disruptions are possible and what is known about traffic

According to a radio station that relayed the water utility’s notice, lower water pressure is possible on the south side of Thahan Street, from Kiakkai Pier to the Saphan Daeng intersection. Both sides of Samsen Road from Kiakkai to Samsen Canal and the west side of Rama V Road from Saphan Daeng to the same canal.

The list also includes Khiao Khai Ka Road and Amnuay Songkhram Road. Both sides of Ruamchit Road from the intersection with Amnuay Songkhram to Samsen Canal, and both sides of Phichai Road from the Phichai intersection to Samsen Canal. In addition, the notice names both sides of Nakhon Chai Si Road between the Ratchawat intersection and Payap Pier.

The list marks areas where low water pressure or a temporary water stoppage may occur, not a confirmed shutdown of every building. Separately, Matichon reported that by 06:30 the water was no longer pooling on the road between Kiakkai and Saphan Daeng, and traffic was normal; this is a morning assessment, not a forecast for the evening.

What to do

Residents of affected neighborhoods were advised by the Dusit district administration to prepare a water reserve by 20:00 on November 12. While water is still coming through, you can fill clean containers for household use and set aside drinking water separately; for details on safe food and water use in Thailand.
