Hydro-Electric Development in India


    RECENT reports from India, referred to in Beama of November, state that a very large irrigation scheme which will include the generation of large quantities of electric power between the Punjab and the State of Bilaspur is under construction. The volume of water that will be impounded is three times as large as that of the Aswan dam across the Nile. A further scheme for the development of water power utilizes the high run-off of the monsoon rains from the High Range Hills to the plain at Travancore in southern India. Power is obtained from the Munnar River as it descends in a series of cascades from the hills. The monsoon waters are impounded in storage reservoirs built on natural sites. The power station is built on the banks of the river, with the tail-race planned to discharge into it. Above stream, the river water is decanted by a weir, then passes through a channel to the tunnel and forebay. From there it is carried in a 10,000 ft. long tunnel— an open channel was impracticable owing to the crumbling nature of the surface rock—to the surge tower. Two parallel pipe-lines connect with the power house, each supplying water to a 6,000 brake horse-power turbine.
