Abstract: National water Policy (1987, 2002) of India which determines that groundwater assets could be utilized only up to its recharge limit, which are mentored of evaluation of groundwater assets. In India methodology for groundwater assets can be widely depends on Groundwater Resources Estimation Methodology, 1997 and had evaluation of annual renewed groundwater resources (recharge) were involved, the percentage of utilization and annual groundwater draft with respect to recharge (state of development). The procedure has been for the delineation of suitable zones for the artificial recharge structures. In addition, the inputs for estimating the groundwater recharge has been derived from the satellite data and computed the balance groundwater reserves available for future use and calculated the stage of groundwater development. The sub-basin wise groundwater resource estimation has also been carried out to prioritise the sub-basins for taking up the artificial recharge structures. Further, based on the suitable zones for artificial groundwater recharge and the prioritisation of the sub-basins, few sites have been tentatively located for taking up artificial recharge structures. The procedure for the delineation of suitable zones for the artificial recharge structures. Several thematic layers have been generated according to GEC-1997 method and estimated the groundwater resource and ground water balance. Based on the results obtained by the analysis in this study, the tentative sites for construction of recharge structures such as percolation tanks, check dams, farm ponds and the de-siltation of tanks have also been suggested. The field investigation is inevitable before implementing any water-harvesting program. Further, the groundwater resource estimation has to be taken up at the regular intervals to know the net balance available for future use.
