The combined deaths in Nepal and China surpassed 900, with more than 4,700 people missing, and a private-sector association representing power companies said at least 900 workers have been unaccounted for from 12 hydropower projects damaged by the floods in Nepal’s Rasuwa and Nuwakot districts.
Mohan Kumar Dangi, president of the Independent Power Producers’ Association, Nepal, or IPPAN, said there’s an estimation of at least 500 of the 900 missing workers trapped in the tunnels, although authorities have provided varying numbers and said several foreign teams were assisting Nepali rescuers.
At least one expert said the tunnels offered enough space for people to take refuge and that some workers could have access to oxygen. But others warned that the chances of finding survivors were diminishing.
Dangi said some workers had managed to make contact and call for help when the disaster struck last Wednesday, and some others who managed to flee reported to authorities and relatives that many of their colleagues were still in the tunnels. But he said that, six days after the disaster, fears grew that some might have suffocated.
“We are working in search and rescue of the stranded people from hills, settlements and river areas,” said Brig. Gen. Raja Ram Basnet, Nepal’s army spokesman.
Nepal’s disaster agency said Monday that 903 deaths had been counted in that country, with 4,247 people, including 592 foreigners, missing. As of Sunday, Chinese authorities reported 16 deaths and 546 missing, and Chinese state media said 261 of the missing were foreigners, including over a hundred Nepalis.
The stations are powered from giant tunnels where people are trapped
Workers shoveling mud from a flood-ravaged power station in Dhading, Nepal, told The Associated Press that the station is a key node for providing power to over 20,000 people in the region. The workers cleaning the power station said they hope that it is not rebuilt near the river.
Rescue efforts are focused on people trapped in the gigantic tunnels built for controlling the waterflow to produce hydropower, across multiple sites.
“The tunnels are built to access hydropower infrastructure and to divert water — an essential step to generate energy. These tunnels are big enough to drive trucks through,” said Jakob Steiner, a geoscientist at the University of Graz in Austria, who is currently based in Dhaka, Bangladesh. “There is enough place for people to take refuge safely inside and from what we understand they have managed to get oxygen to some of those stuck inside and are trying to rescue them now. It’s a race for time though as people need food and water."
In the Upper Trishuli-1 Hydropower Project, in the hard-hit Rasuwa district, at least 576 were missing, Dangi said, adding that around 300 of them were believed to be trapped inside the project’s tunnel. Rescuers have been trying to find survivors for days, working through the rain.
At the Trishuli-3 Hydropower Project, crews were working to descend about 15 meters (50 feet) into the tunnel in an effort to reach those believed trapped inside, according to Basnet, the army spokesperson.
