Ranchi, July 30: Jharkhand has embarked on a mammoth project to rejuvenate five dams and reservoirs that act as prime water sources for capital Ranchi, Jamshedpur, Hazaribagh and Chatra, a move that will also help the state tap central funds. The water bodies that have been chosen include Getalsud and Kanke in Ranchi, Sitarampur dam in Adityapur, Chharwa dam in Hazaribagh and Heroo reservoir in Chatra. The project envisages assessment of siltation and de-silting of dams using scientific methods, undertaking pollution prevention measures by interception, diversion and treatment of sewage by providing low-cost sanitation, treatment of catchment areas and other allied work as per norms of the Jawaharlal Nehru National Urban Renewal Mission (JNNURM) and National Lake Conservation Programme (NLCP).
