Abstract: In the present scenario of global warming, the availability of drinking water is the main concern. The problem of water shortage tackled in reliable scientific approaches. Rainwater harvesting is one of the best practices in collecting and storing rainwater. This method is cost-effective in the planning and development of rainwater harvesting facilities in water-scarce areas for future needs. In this paper, a case study of Vardhaman College of Engineering, Hyderabad, in Telangana state has taken to estimate the rooftop rainwater harvesting potential. In this study, In this study to digitize the various types of rooftops, Google Earth Pro is used. The overall potential quantity of rainwater harvestable at the institutional level can be assessed by using ArcGIS. Total water demand for the study area is calculated considering the existing population. Rainwater harvesting sites are identified and proposed according to the lowest elevation and drainage direction of the study area. The volume of the storage tank is designed based on daily discharge by assuming the length, breadth and height. The results of this study will demonstrate the Applications of Google Earth Pro and GIS in estimating rainwater harvesting potential to tackle the prevailing water shortage in the study area. Rainwater harvesting provides water at the point of demand, minimizes the stress on existing natural resources and also an eco-friendly solution.
