Dudh Khola Hydroelectric Project (65MW)

HTR is carrying out Detailed Engineering Design of the headworks of the Run of River hydropower project of capacity 65MW located across the Dudhkhola River in Manang District.

Major features:

Design Discharge 18.05m3/sec, Gross head 447.46m, Plant Capacity 65MW

The headworks of the Dudh Khola Hydropower Project are located on the left bank of the river, while all remaining structures lie on the right bank. The headworks comprise a 35 m long concrete-infilled boulder diversion weir with a crest level of 2,367.50 masl, designed to safely pass the 1:100-year flood, along with side intakes, sediment exclusion structures, a gravel trap, settling basin, headpond, and headrace pipe. The scheme diverts a design discharge of 18.05 m³/s with overload and flushing capacity, conveying flow through a steel headrace pipe and siphon to a 4.25 km long inverted D-shaped headrace tunnel, followed by a surge shaft and penstock system. Power is delivered to the powerhouse through vertical and inclined penstocks with bifurcations feeding multiple turbines, forming an efficient run-of-river hydropower layout.
