The intake leads to the rectangular profiled headrace channel of 1,800 m length which was made of reinforced concrete. The headrace channel lies on the right bank of the stream and it has 4.4m inner width and 2.2m of wall height while the design flow is 27m3/s. This bank has moderately steep slopes, and the bedrock is marginally weathered. Reinforced concrete channel sections were placed on screed concrete and expansion joints were provided at every 17m with 250mm wide rubber water bars.
