Designing rooftop rainwater harvesting system at RK University

Abstract

With Advancement in industries and a huge increment in population, The Gap between water demand and Water supply is continuously broadening. According to a United States geological survey, the availability of total water on earth is estimated as 1.386 billion km3 with 97.5% saltwater and 2.5% fresh water. Only 0.3% of total freshwater is available in liquid form. Population of human beings is around 7.6 billion and 2 billion more people will be added in 2050. It has led to increase emphasis on optimal management of water resources. Rainwater harvesting is the engineering solution to water problem in urban area. In the proposed work, School of Engineering (SOE), RK University Building is taken as a study area to plan, analyze and design rainwater harvesting system to conserve the roof top water for the use in dry seasons. Detailed survey had been carried out in SOE building using QGIS and Effective design of tank had been given to store rainwater during whole year. By adopting this water conservation method, one can use rainwater for drinking and other purpose in dry season also.
