Live storage at present constitutes only 10% of the total water potential of the country. Hand in hand technology development in drilling and pumping methods has paved the way for massive exploitation of groundwater mainly for irrigation (85%) and for industry and domestic purposes (15%). Such a localized over drawl of ground water has to be compensted adequately by harnessing surplsus monsoonal flows along with expansion of water storage copacities in enhancing the water availability. Stress would need to be laid on conjunctive use of surface and ground water in irrigated commands. Tube wells and wells are the major sources of irrigaton in our country. About 30% of the pump sets is also as low as 30-33% only. IS pumps should therfore be used and the worn out parts be replaced. Use of PVC pipes in place of conventionals GL would also help in reduction of friction losses therby the pumping cost. Canal irrigation systems generally are about 40% efficient resulting in wastage of water and thereby low irrigation efficiencies. On-farm development work to avoid loss of water is therefore critically important.
