Project Background:

Since Project was devastated by an unprecedented natural calamity two years ago, which left the entire project in a deplorable condition as well as for an uphill task to re-shape the work site for any renewed construction activities. There are Underground component of the project; which were already been constructed and remained as intact, except choked inside Figure: Powerhouse and Tail Race Channel Section with the river bed materials; but most of the surface structure were got damaged to such an extent that the said structure became unserviceable to serve the requisite functional requirement for the project in particular, Intake weir, Surface water conveyance structures etc. The major challenge in this project was to match with the invert level of tunnels at inlet and outlet as they were already constructed in accordance with earlier planning.
