Smartphones, smart watches, smart cars, and smart grids - everything is smart nowadays, even water. Living in the smart city, Bhubaneswar, I have never encountered a lack of fresh water. However, the global picture looks quite different. Water scarcity affects every continent. According to a UN investigation, around 1.2 billion people live in areas of physical water scarcity. A further 1.6 billion people face economic water shortages (where countries lack the necessary infrastructure to take water from rivers and aquifers). There is enough fresh water on the planet for 7 billion people but it is distributed unevenly and too much of it is wasted or polluted. This study will find a solution of this problem.
