Rainwater trait is a critical factor deciding about its appropriateness for using it as a source of drinking water. But the hasty increase in industrialization and urbanization has badly decreased the rainwater quality these days. This present study has been carried out with a view to analyze the quality and suitability of roof-top harvested rainwater for drinking purpose. To carry out this experimentation work the rainwater was collected from the various selected roof-tops and was tested for certain duration to study various parameters regarding its quality with reference to the Indian Standards on storage with respect to time. The objective is to know variations in the different chemical parameters of the stored water with time which may occur during its storage and it is necessary to figure out before using as drinking water. The rainwater was assorted from two different locations within the study area, based on surroundings of roof material, on the material of downpipe and different pollution level based on traffic load in the vicinity. The experiments carried out in the present study provide a precise methodology for storing the harvested rainwater with respect to different material and temperature with time.
