Abstract

Objectives: The main objective behind this experimentation is to find the suitability of roof-top harvested rainwater with respect to its quality and to know about any changes that may occur in the parameters of the stored water and are essential to know before using it as potable water and to know about the different storage methodologies. The present study attempts to analyze the condition of rainwater harvested from the roof-tops so as to use that water as a source of drinking water. Methods/ Statistical Analysis: Rain water quality is an important factor which governs its suitability for potable use. But due to a rapid boost in the development particularly industries the rainwater trait is depreciating. For carrying out this study the rainwater was collected from the top of roofs and has been analyzed for a sanguine span to figure out its trait in consonance with the parameters for the potable water as given in Indian Standards on reserving for future with regard to time. The rainfall was collected from the dual contrasting locations from the concerned area under study i.e., Indian Institute of Technology, Roorkee campus, India based on the material of downpipe, surroundings of roof material and deviating levels of pollutants in atmosphere owing to the traffic load of the area and was stored under different materials to analyze for its quality through different quality tests on the various physical and chemical parameters. Findings: The experiment will result into finding of an appropriate approach regarding efficient roof-top rainwater harvesting and also the correct technique for the stashing of the rainfall gathered as well as to throw light on the aspects of temperature and material amidst time. Applications/Improvement: The similar experimentation can be carried out at other places as well with more locations for more diversity in the results attributing to the surroundings etc. to get a clearer and precise view about the roof-top harvested rainwater quality.
