Due to seasonal, geographical and annual variation in
availability of water as well as lack of adequate storage, substantial
quantity of water, especially during monsoon season, remains unused and
flows into sea. As per present assessment, the average annual water
availability in the country is 1869 Billion Cubic Meter (BCM), i.e.,
about 66000 Thousand Million Cubic feet (TMC ft). Further, it has been
estimated in the year 2009 by Central Water Commission (CWC) that about
450 BCM (15890 TMC ft) of surface water and by Central Ground Water
Board (CGWB) that about 243 BCM (8580 TMC ft) of ground water are being
utilized for various purposes. Rest of the water 1176 BCM (41524 TMC
ft), i.e., 62.9% of available water may be considered as flowing down to
sea.
The Ministry of Water Resources (MoWR) (erstwhile Ministry of Irrigation) formulated a National Perspective Plan (NPP) for Water Resources Development in 1980 envisaging inter-basin transfer of water from surplus basins to deficit basins/areas. National Water Development Agency (NWDA) set up in 1982 for carrying out various technical studies to establish the feasibility of the proposals of NPP, has identified 14 links under Himalayan Rivers Development Component and 16 links under Peninsular River Development Component.
Five Peninsular links namely (i) Ken – Betwa, (ii) Parbati – Kalisindh – Chambal, (iii) Damanganga – Pinjal, (iv) Par – Tapi – Narmada & (v) Godavari (Polavaram) - Krishna (Vijayawada) have been identified as priority links for taking up their Detailed Project Reports (DPRs). DPR of one priority link namely Ken-Betwa has been completed and was communicated to the party States. Modifications of the proposals and final Detailed Project Report preparation have been taken up by NWDA in the light of observations of the concerned States. The Ken-Betwa link project has been included in the scheme of National Projects.
Further, after receiving the concurrence of the concerned States, NWDA has taken up the DPRs of two more priority links namely Par-Tapi-Narmada & Damanganga-Pinjal. Efforts are on to arrive at consensus amongst party States on the other priority links.
