Dewatering and inspections aim to reduce structural and environmental risks.

Sealing Begins on Lohari Nagpal Hydropower Tunnels After 15-Year Stalemate.

The process to permanently seal six tunnels of the stalled Lohari Nagpal hydropower project has begun, bringing closure to a project halted since 2010. Accumulated water inside the tunnels is being removed through dewatering, after which detailed structural inspections will be conducted. Officials said unstable or weakened sections will be reinforced before both ends of each tunnel are sealed with concrete plugs about five metres deep. The project, initiated in 2006, was stopped after nearly 70% completion following widespread protests over environmental concerns and the sanctity of the Ganga. It was later formally scrapped by the government. According to Uttarakhand Jal Vidyut Nigam Limited (UJVNL), the sealing exercise is expected to cost around ₹22 crore. Officials noted that prolonged stagnation and water accumulation posed risks to unfinished structures and nearby hillside villages, making the sealing operation essential for long-term safety and environmental protection.
