THE BEGINNING OF THE JOURNEY Vedas have highlighted its importance. First Conceptual Proposal for Storage reservoir in I quote a few words from Yajurveda: July 1941 by Shri Diwan Bahadur L Venkata Krishna Iyer, Chief Engineer in Madras Presidency. vkiks fg”Bk e;ks Hkqo%] LFkk u ÅtsZ nèkkru& Finally approved with FRL +150 ft and Storage ;ks o% f’koreks jl%A Capacity of 194.6 TMC as per GWDT Award, 1980 Broadly, it translates to: Water is the Accorded National Project Status - A.P. life-giver on earth. It is a great source of Recogranization Act, 2014 energy. It is the most beneficial elixir. 2
