Dhami said that the Population of Dehradun is increasing rapidly due to which the demand for drinking water is also consistently increasing. In view of this and considering future needs a project is proposed on Song river which is a tributary of Ganga. He said that the estimated cost of the project is Rs 2021 crores. The project envisages providing 150 MLD drinking water by use of gravity to Dehradun and its peri urban areas. A population of about 10 lakh would get drinking water from the project. Dhami said that the project once completed would end the dependence on tube-wells for providing drinking water. A 3.5 km long lake would also get formed due to the Song dam which apart from providing impetus to tourism and creating new EMPLOYMENT opportunities would help in preserving the Environment. The CM told the union finance minister that flood control is another objective of the project. The project would provide protection to a population of 15000 in 10 villages from the floods which affect them every year.
