Nepal Flash Flood Traps Workers, Survivor Alleges Chinese Supervisor Fled

A devastating flash flood struck the Trishuli-3A Hydropower Station in Nepal, trapping several workers inside a tunnel. According to Raj Chhetri, a worker who survived the disaster, a Chinese supervisor fled the tunnel after workers sensed danger, leaving many behind.

Chhetri was working inside Tunnel No. 3 when workers heard a loud noise, prompting him to approach the supervisor for permission to leave. The supervisor allegedly told Chhetri that he would go and check on the situation before leaving the tunnel himself. However, the supervisor did not return, and shortly afterwards, a powerful torrent of water, mud, and debris swept into the tunnel, carrying away workers, vehicles, and personal belongings.

Chhetri estimated that around 265 people were working inside Tunnel No. 3 when the disaster struck. He claimed that bodies could be seen deeper inside the tunnel and that cries for help could still be heard from trapped workers. Chhetri and three other workers managed to flee, but two of their colleagues are still missing.

The incident occurred amid a series of flash floods and mudslides that struck Nepal's Rasuwa and Nuwakot districts around August 26. The disasters caused extensive destruction along the Trishuli River, severely affecting hydropower projects and leaving workers trapped inside tunnels filled with mud and debris.

The Trishuli-3A project involves Power China Corporation, whose personnel are involved in supervising engineering work at the project. The Nepali Army has been leading rescue and recovery operations at the affected hydropower sites, with assistance from tunnel and technical specialists from China, India, and other countries.

Rescue teams have been working to clear tonnes of mud and debris, drilling into blocked sections, supplying air and essential materials, and using controlled explosions where required to reach inaccessible areas. Several workers have been rescued, but difficult terrain, unstable conditions, and heavily blocked tunnels have continued to hamper efforts to locate those still missing.

The flash floods and mudslides have caused widespread destruction and disruption in Nepal, with many workers still unaccounted for. The rescue operations are ongoing, with teams racing against time to locate and rescue those trapped in the tunnels.

The incident highlights the risks and challenges faced by workers in the hydropower sector, particularly in remote and vulnerable areas. The alleged actions of the Chinese supervisor have raised concerns about the safety and well-being of workers on such projects.

In the aftermath of the disaster, the Nepali government and international organizations have been working to provide support and assistance to those affected. The incident is a reminder of the importance of prioritizing worker safety and taking measures to prevent such disasters in the future.

The rescue operations are expected to continue in the coming days, with teams working tirelessly to locate and rescue those still missing. The incident has sparked concerns about the safety and security of workers in the hydropower sector, and an investigation into the incident is likely to be launched.

The flash floods and mudslides have caused significant damage to the hydropower projects in Nepal, with many workers still unaccounted for. The incident is a reminder of the importance of prioritizing worker safety and taking measures to prevent such disasters in the future.

In conclusion, the flash flood that struck the Trishuli-3A Hydropower Station in Nepal has resulted in a devastating disaster, with many workers trapped inside a tunnel.

The rescue operations are ongoing, with teams racing against time to locate and rescue those trapped in the tunnels.
