Rainwater Harvesting Strategy For The Kolkata Metropolitian Area

There is no doubt that water scarcity is a problem, not only confined to the global scale but also to regional scales. Narrowing the issue to our country India, more so for the state of West Bengal, the issue is quite alarming. As a whole, the condition of the state of West Bengal is quite dismal as far as the availability of groundwater is concerned. One of the solutions to mitigate this issue happens to be rainwater harvesting. The present pilot study relates to the feasibility of rainwater harvesting as a probable solution to the increasing water demand for the metropolis Kolkata, particularly with respect to one of the sectors, such as the residential sector. This paper presents a comprehensive study of integrated management including issues and challenges for maximum possible utilization of rainwater for the mentioned residences to reduce the water requirement from the Kolkata Municipal Corporation (KMC) and groundwater sources.
