National Water Development Agency (NWDA) was set up in July, 1982 as Autonomous Society under the Societies Registration Act, 1860, to carry out the water balance and other studies on a scientific and realistic basis for optimum utilisation of Water Resources of the Peninsular rivers system for preparation of feasibility reports and thus to give concrete shape to Peninsular Rivers Development Component of National Perspective. In 1990, NWDA was also entrusted with the task of Himalayan Rivers Development Component of National Perspectives. Recently, the functions of NWDA have been further modified and the work of preparation of detailed Project Reports (DPR) of various link proposals and Pre-feasibility Reports and feasibility reports of intra-State links as proposed by the States have been included in the functions of NWDA.
FUNCTIONS OF NWDA:
a) To carry out detailed surveys and investigations of possible reservoir sites and interconnecting links in order to establish feasibility of the proposal of Peninsular Rivers Development and Himalayan Rivers Development components forming part of National Perspective for Water Resources Development prepared by the then Ministry of Irrigation (now Ministry of Water Resources) and Central Water Commission.
b) To carry out detailed surveys about the quantum of water in various Peninsular River Systems and Himalayan River Systems which can be transferred to other basins/States after meeting the reasonable needs of basin/states in the foreseeable future.
c) To prepare feasibility report of the various components of the scheme relating to Peninsular Rivers development and Himalayan Rivers development.
d) To prepare detailed project report of river link proposals under National Perspective Plan for Water Resources Development after concurrence of the concerned States.
e) To prepare pre-feasibility/feasibility report of the intra-state links as may be proposed by the States.
f) To do all such other things the Society may consider necessary, incidental, supplementary or conducive to the attainment of above objectives.
