Rainwater Harvesting in India

Abstract

The objective of this article is to provide awareness into the process of rainwater harvesting so as to make people proactive in conserving fast depleting water resources through this technique, which has been used in India from time immemorial, but is now forgotten behind the insignia of modernisation. The article highlights the benefits of rainwater harvesting such as: provision of an economical water conservation measure, reduction of the burden on other sources of water, provision for agriculture when there is no rainfall, alternative and cleaner source of drinking water, prevention of top soil erosion, reduction of the possibility of floods, improved plant growth, greater responsiveness of water provision, and connection of water supply to natural water cycle. It also gives information regarding the rainwater harvesting practices in some countries abroad for further comparison and research into those practices by those who feel interested. Details of different techniques of rainwater harvesting are furnished so as to inculcate interest in the process. Calculation of rainwater harvesting potential is also discussed for estimating the possible benefits. How far India has moved in this direction is briefed for those who would want to bring about changes connected to their micro set up or policy making at macro level. The article is an endeavour to give a factual picture of rainwater harvesting in India, with the hope that it would inspire more popular implementation of this futuristic source of water conservation.
