The Internet of Things (IOT) Based Smart Rain Water Harvesting System

Ground water all over India is depleting fast. Niti Aayog has cautioned that Delhi could run out of ground water by 2020. This is a critical situation and can happen with other parts of India too. Conservation of water is the need of hour. Due to vast globalization, urbanization and modernization the quality of our surrounding is degrading which in turn is affecting the natural phenomenon of raining too. The gases such as Sulphur Dioxide and Nitrogen Dioxide released due to burning of fossil fuels gets transported by air and wind currents. They mix with water and other material to form sulphuric acid and nitric acid causing acid rain. The problem in harvesting arise here as this water is not suitable for use. Storing this water in the same reservoir with slightly better quality of water can lead to degradation of that water also. Out of 1200 millions of gallons per day (MGD) demand of water, 200 MGD requirement of Delhi is met by illegal boring of water. Under a regulation of 2012, it has been made mandatory for all establishment above 100 sq. m to have rain water harvesting system (RWHS). Small size houses already constructed also need to be addressed. A major issue is not only harvesting of water but also the quality of harvested water. Present paper seeks to find answer to all these problems.
