About Us
Song Dam is proposed to be constructed across Song river, a tributary of river Ganga, near village Sondhana in District Dehradun of Uttarakhand. The dam is proposed to cater the drinking water needs of Dehradun city and surrounding areas.
The physiographic parameters of the river catchment at Satyanarayana site / Song dam site have been estimated by GIS processing of STRM DEM. The catchment area of Satyanarayana site comes out to be 963.7sqkm whereas catchment area upto the proposed Song dam site is 85.225 sqkm.
The project will be helpful in supplying the water through gravity and so the huge expenditure involved in pumping the water will be saved. By construction of the dam some of the water will seep into the ground and will supplement the ground water table which, in turn, will enhance the output of tube wells in the vicinity and Storage of water will help in recharging the ground water and augmentation of natural water sources in downstream. Rivers like Rispana, Bindal and other small streams may get recharged and ground water level in vicinity of Dehradun will also be increased. Tourism and Fisheries may also be developed.
Background of the project
According to the availability of water at the proposed site, the scheme can cater the domestic water demand of additional 15 lakh people at the rate of 135 lpcd for Dehradun city and suburban areas.
