Teesta project not affected by Sikkim quake: Teesta Urja Ltd

"No section of the tunnels of project works, at Saffu or at any other location on the site, is flooded or has collapsed," the company said in a statement here.

"All the major structures are intact and safe," it added.

The project site is situated on the Teesta river, in Mangan district of North Sikkim. The project components, such as the dam, tunnels and power house, are spread over the areas between Chungthang and Mangan.

This area, along with other parts of North Sikkim, were affected by the earthquake in Sikkim and other areas of the North-East India on September 18.

The company said none of its personnel are trapped inside the tunnels.

"All casualties, injured and missing employees of the company have been fully accounted for and all other employees are safely housed in various project locations and temporary camps," it said.

Army personnel involved in rescue operations in Saffu could not reach the project site by road, owing to landslides in the area. They commuted from Theng village to Saffu through the project tunnels, which are clear and safe.

"A 30-member company of the Sikh Regiment, led by their Commanding Officer, Colonel Dogra, was able to go through the above tunnels and have seen the conditions. This army platoon has been staying at the camp site of the project in Saffu since last night," it said.

The company said its officials have also driven through this tunnel from Theng village to Saffu and also to Chungthang several times since September 19 for transporting men and materials and are carrying out relief operations.
