Abstract: Water is one of the basic requirements vital for the healthy functioning of the world?s ecological - system however, because of the increase in population, growth in industrialization and urbanization it has led to an increase in the demand of fresh water therefore leading to a decrease in the availability and supply of fresh water. Water like any other natural resource is very important for a nation?s economic growth especially in terms of agriculture goods and manufactured products. Less supply and availability of water can affect the production level and harm the entire economy. Now, there is a universal recognition that grey water can be used as an alternative source for purposes like irrigation, toilet flushing and others. This paper seeks to understand the several major economic causes and problems of water scarcity. It also examines the level of social awareness on water scarcity and grey water, what are the various purposes of using Grey water. The main objective of this study is to explore the impact of information nudge on the willingness to reduce daily water requirement and opt for the use of grey water for the better management of water resource and also make a comparative nudge study on the average number of families on their maximum and minimum daily water requirement. Primary data has been collected through structured questionnaires. An experimental design has been used in this study. Responses before and after provision of information nudge has been studied. The results revealed that there is a significant association of overall social awareness and reusing of grey water as an alternative source for various other purposes.
