The Mai Hydropower Project is a 22MW project carried out by our associates in Nepal. It comprises a 10m high concrete gravity dam built at an elevation of 320m above sea level.
The design flow of the scheme is 23m3/s and this is conveyed to the powerhouse through a combination of a 1km headrace culvert and a 2km headrace tunnel.
The powerhouse is furnished with three 7.6MW Francis turbines.
The length of the headrace tunnel is 2192m and the section is inverted D-shaped with cross-sectional area of 13.1 square meters. The tunnel has a concrete lining in the invert and appropriate rock-support for the rest of the length.
