About the Project

The project diverts 18.00 m³/s of flow from the Madi River by constructing an ogee-shaped concrete diversion weir with the crest elevation at 1344 m above mean sea level (amsl). The diverted flow through the side intake passes through a gravel trap. From the gravel trap, the discharge is conveyed to a conveyance tank. Two inlet tunnels of dimensions 4.2 m X 4.2 m convey the design discharge to two separate chambers of the underground settling basin. From the settling basins, the flow is conveyed through a 5.34 km headrace tunnel along the left bank of the Madi River. After the headrace tunnel, the design discharge is conveyed via about 1636 m long penstock pipe to three generating units of Francis turbine inside the semi-surface powerhouse. From the powerhouse, the water is conveyed back to the Madi river through about a 195 m long tailrace culvert.
