Sengulam dam is constructed as a part of Sengulam Hydro Electric Project for forming a balancing reservoir. Water required for power generation is stored in a very small reservoir created by constructing a dam across Sengulam stream, a small tributary of Muthirapuzha river. The Project utilises the tail water of Pallivasal Power House. The tail water of Pallivasal HE project collected in the forebay near the power house and is pumped over a head of 9.14 m and carried to Sengulam balancing reservoir through a tunnel of 1728.20m length. The water conductor system from the reservoir to power house consists of 1759m long power tunnel, 808m long Low pressure Pipe and 960m long twin penstock. These penstock pipes bifurcate and feeds 4 machines of 12MW each. Tail water is released to Muthirapuzha river.
