In South India, tank irrigation is one of the major traditional sources of irrigation. Area irrigated by the tanks has been constantly in decline due to other modes of irrigation, shortage of rainfall, loss of farmer’s interest, financial problem etc. Farmers are more dependent on ground water rather than surface water. The overall objective of the study was to compare the technical efficiency of water use in system and non-system tank command farmers. Water is available only for six months from November to April of every year in both the tanks. Non-system tank command farmers used less water than system tank command farmers and got comparatively higher yield than system tank command farmers. The yield per m3 of water was worked out to be 1.04 kg per m3 of water for farms in non-system and 1.00 kg per m3 for farms in system tank. The mean technical efficiency of system tank command farmers was estimated as 87% and the mean technical efficiency of non-system tank farms was estimated as 91%. System and non-system tank command had no difference then why we conflict with neighbor state. Approximately, we are consuming less than 10% of rain water to grow our crops, supply our homes, keep our industries running, and generate electricity. If we use rain water judiciously no water conflict will occur.
