Provision and Scope of Rain Water Harvesting at the Elitte College of Engineering

Abstract

As the population of world increases, the demand for quality drinking water is also increasing. Therefore, the saving of water became very essential. Many nations adopted rainwater harvesting which is an old practice as a viable decentralized water source. The definition of rainwater harvesting is the technique of collection and storage of rainwater at surface or in sub-surface aquifer before it is lost as surface run off. Due to depletion of groundwater resources, the only way to solve the water problem is rainwater harvesting. The rainwater will be not only useful, but also helps to improve the quantity and quality of water. Here our focus is to construct a underground water reservoir to store the rooftop rainwater and use the water for washroom purpose. The methodology includes collection of rainfall data, finding out the area on which rainwater can be harvested for storage, calculating the volume of storage tank, quality analysis of rainwater, treatment for rainwater, how to reuse the water for college purpose.
