Abstract: Globally, water scarcity is being witnessed at every corner of world irrespective of resource availability. The fresh water sources either surface or ground water resources are in constant peril owing to pollution, degradation and over exploitation. Judicious use and sustainable water conservation practices are the need of the hour. In an effort towards sustainability, an initiation has been taken up in Jawaharlal Nehru Technological University Hyderabad campus to recharge rainwater artificially into the aquifers. In the study area, five rainwater recharge structures with 9 injection wells at different locations were constructed for harvesting the rain water and recharging into the confined and unconfined aquifers. Apart from these, three Piezometers were drilled in the campus to study the groundwater level fluctuations due to artificial recharge. An attempt is made to monitor these injection wells. Physico-Chemical water quality parameters like pH, TDS, EC, Total Hardness, Chlorine, Fluorine, Nitrate, Sulphate, Calcium, Magnesium, Carbonates, Bicarbonates, Sodium and Potassium parameters were tested for samples collected from these injection wells. Spatial analysis has been developed in GIS environment from the results of physico- Chemical parameters and is compared with BIS: 105000, 1991 standards.
