Madhyamaheswar Small Hydro Electric Project Uttarakhand Jal Vidyut Nigam Limited The Madhyamaheshwar Small Hydel Project is located on the river Madhyamaheshwar Ganga. The project is located in the Ukhimath tensile of Rudraprayag district of Uttarankhand. It is proposed to have an installed capacity of 15MW with three (03) units of 5MW each with a design head of 181.0m. Salient Features: Capacity : 15 MW (3unit X 5MW) Design Head : 181.0m Weir : Length = 142.00m Height = 2.90m De-silting Tank : Length = 42.00m Width = 18.00m Head Race Tunnel : Length = 3928m Width = 2.75m Size of Fore-bay : 42m x 9m x 3.70m Length of Penstock : 490m Size of Power House : 45m x 14m x 21.30m Figure: Diversion Weir, Intake & De-silting Tank Layout Geology : Fill, River Boulder, Overburdened, Granite in Hill. Project Cost : 75 Crores Client: UJVN Limited 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.
