Water is considered as everlasting free source that can be acquired naturally which is essential for environment, food security and sustainable development. Sustainable use of water could maintain a balance between its demand and supply. Sustainability of RWH in meeting the household demands of fresh water is the prime focus of this study. The method of this study comprises of various literature reviews. Availability of drinking water and provision of sanitation facilities are the basic minimum requirements for healthy living. Rainwater harvesting is the most traditional and sustainable method, which could be easily used for potable and non-potable purposes both in residential and commercial building. Rainwater harvesting, in its broadest sense, is a technology used for collecting and storing rainwater for human use from rooftops, land surfaces or rock catchments using simple techniques such as jars and pots as well as engineered techniques. Rainwater harvesting has been practiced for more than 4,000 years, owing to the temporal and spatial variability of rainfall. Rainwater harvesting describes processes in which precipitation that falls on a site is diverted, captured, and stored for use on-site, as opposed to allowing it to run off, evaporate, or infiltrate into the soil. Depending on its intended use, the captured precipitation may require treatment. In a broad sense, rainwater harvesting can also include capture from surface water runoff rapid population growth, combined with industrialization, urbanization, agricultural intensification and water intensive lifestyle is resulting in a global water crisis. Sustainable rainwater harvesting provides the long-term answers to the problem of water scarcity. This paper mainly conveys importance of RWH and factors to be considered for rainwater harvesting system and new technologies used in this system.
