Rooftop Rainwater Harvesting in Urban Areas of India

Abstract

Water is very important for survival of every human being. India is blessed with adequate rainfall. It is estimated that rainwater captured from 1-2 percent of India’s land can provide water to 950 million persons at 100 liters per person per day. With the development and growth of urban population, the paved area and roof area is also increasing and this situation is ideal for implementing rainwater harvesting techniques. This paper highlights various benefits, components, potential, need, techniques, structure and case studies of rooftop rain water harvesting in urban area.
