Design of Rooftop Rainwater Harvesting System for Dr. Babasaheb Ambedkar Marathwada University (Dr. BAMU) Sub-Campus, Osmanabad

Rainwater harvesting is one of the most commonly used methods to save water. It refers to storing of rainwater for various uses. The notion behind rainwater harvesting is to not waste the rainwater and prevent it from running off. This method is very useful considering the water scarcity that is happening in India. As we know that surface water is not enough to meet the demands of the people, we can get additional help from rainwater. Also, most people now depend on groundwater for their uses. Many houses and even flats have submersible pumps in their place. The groundwater is decreasing day by day because of excessive usage, deforestation, urbanization and more. It is therefore necessary to make decisions about conservation and allocation of water that are compatible with social objectives such as economic efficiency, sustainability and equity. When we practice rainwater harvesting, it can maintain the level of the groundwater. Moreover, rainwater harvesting prevents water from logging on roads. It also reduces the chances of soil erosion. Most importantly, rainwater harvesting improves the quality of water which we consume, as it is the purest form of water. At the rate in which India populace is expanding, India has surpassed China from its number 1 position of most thickly populated nation of the world in 2023. These will prompt high rate of utilization of most profitable regular asset; Water's subsequent in enlargement of weights on the allowed freshwater assets. Old technique for damming waterway and transporting water to urban zone has its own issues of everlasting inconveniences of social and political. The specialized parts of this paper are water harvesting collected from rooftops which is thought to be catchment territories from all lodgings and Institutes departmental working at Dr. Babasaheb Ambedkar Marathwada University, Sub Campus situated at Osmanabad. Osmanabad is one of the districts of Marathwada region in Mahararashtra state which comes under the water scarcity zone. Osmanabad receives an average rainfall of 780 mm. As a matter of first importance, required information are gathered i.e. catchment zones and hydrological precipitation information. Water gathering potential for the inns and workforce flats is ascertaining, and the tank limit with appropriate plan is to consider.
