Abstract

Water is the basic survival element for any living being and human is not exception of that. Though this ‘Blue Plant’ is named after the abundance of water, still there is non-availability of clean, potable water. As India is the second most populous country in the world with a sixth of world population and the figure stands around 1.38 billion, demand of safe pure water is a crucial thing to look at. There are few metropolitan cities in India and Kolkata is one of them which has been growing day by day as a city with a lot of opportunities in all fields. It is common that beside the existing population, Kolkata is attracting more people. This is causing an exponential growth of population and their demand to access to the potable, safe water. The growth projection of the city needs to be kept in mind for meeting the water demand of the population which is discussed here in the thesis work. In Kolkata, water supply is taken care of by Kolkata Municipal Corporation through their water supply department after necessary purification. The analysis and assessment of the qualitative and quantitative parameter of the water is a concern of this thesis work.
