Construction of the First RCC Dams in India at Ghatggar
The Ghatghar Project is owned by the Government of Maharashtra Water Resources Department (GoMWRD) and is located some 200km northeast of Mumbai. The construction of the three RCC dams that form part of the Project faced a number of uncertainties;first they were the first RCC dams in India and thus would be under very close scrutiny, and secondly the ambient conditions would be difficult, the average rainfall on the site was circa 5500mm and thus construction was only possible for eight months of the year with the need to be able to pass a potentially large flood through the site during the four months of the monsoon. In addition temperatures in the high 40s could be expected during the months just prior to the monsoon. Nevertheless in spite of these potential problems the dams were all successfully completed in a very short time. The layout of the scheme gave the Project one large advantage. Ghatghar is a pumped-storage scheme with an Upper Reservoir on the top of a 500m high escarpment and a Lower Reservoir at the bottom. The Upper Reservoir is created by two dams, the Saddle Dam that is only 9m high and the Upper Dam that is 15m high. The Lower Reservoir is impounded behind the Lower Dam that is circa 85m high. Thus the upper dams could be considered to be two large full-scale trials for the larger Lower Dam.
