For the study of impact of artificial recharge of roof top rainwater on the quantity and quality of groundwater, the geomatic approach was employed for identifying sites for construction of roof top rainwater harvesting structures by preparing various spatial maps. Monitoring and assessment of groundwater levels was carried out in the study area. Normal annual rainfall in the campus of Jawaharlal Nehru Technological University Hyderabad is 821mm with unutilized non-committed surplus monsoon runoff.
