North Lakhimpur: A massive landslide at NHPC’s much-delayed 2,000 MW Subansiri hydro project along the Assam-Arunachal Pradesh border on Friday completely blocked the only functional diversion tunnel, thereby significantly obstructing water flow through the river, officials said.
A NHPC Subansiri Lower Project spokesperson told PTI that the diversion tunnel (DT) number 1, which was the only one in use, was blocked due to a landslide at about 11.30 am.
There has been no report of any human casualty due to the incident.
