Abstract: Water is one of the most necessary and essential natural resource which is found both in surface and subsurface areas of the earth to sustain human life, animals and plants. Expansion of population, agricultural activity leads to increment in requirements of freshwater. Groundwater is a major source of freshwater; it may serve as the base flow for rivers, or act as underground reservoir from which water can be extracted for different requirement. These days, the investigation of ground water potential zone mapping was conducted using geospatial approaches. Such applications were expanded and beneficial in identifying viable areas with minimal cost and short timelines, especially in underdeveloped countries where research funds were constrained. The research site experiences high shortage in satisfying the water requirements of the community. Therefore, it is necessary to investigate groundwater potential areas through low cost methods of geospatial techniques. For this reason, land use, soil, drainage density, lineament density, rainfall, slope, and geology of the catchments were considered as the governing parameters for the potential site identification. Analytic Hierarchy Process (AHP) was applied to select the major influencing factors for the site. Finally, weighted sum of overlay analysis was applied and the potential sites were validated through ground truth points (borehole data).
