The scarcity of water is the basic problem faced in many parts of the world. The water sources like well, river and reservoirs are not adequate to fulfil the water demand of people. In urban areas of Bengaluru due to urbanisation, increase in the number of industries and also reduction in water availability in the Cauvery River basin mainly due to variation in precipitation levels, shortage of water has become a major problem faced by the people. Rainwater harvesting is the simple process or technology used to conserve rainwater by collecting, storing, conveying and purifying of rainwater that runs off from rooftops of buildings, parks, roads, open grounds, etc. for later use. This paper discusses about the opinion of people about the methods of rain water harvesting along with the expenditure, advantages and limitations of the usage of harvested water and also the effectiveness of rain water harvesting as a domestic water supply in urban areas of Bengaluru, with the help of sample data collected from a sample survey.
