Review on Rooftop Rainwater Harvesting

Abstract

Water crisis is serious problem in our country. The rapid urbanization and population explosion have triggered massive demand for quality drinking water than ever before. Water for both irrigation and human consumption, is getting more and more scarce for vast masses of our people and in many regions of the country. Many of the water sources like rivers, ground water streams and lakes are drying up. Rainfall patterns are changing drastically, with the massive deforestation leading both to reduced rainfalls as well as to reduced recharging of underground water. So as an option to fulfil the demand due to unbalanced rainfall having water backup needs, rainwater harvesting system necessary for saving the water and would help in reducing water wastage. The aim of present study is to use rainwater and design the effective plan by which we can collect rain water into a storage for our campus. The rainwater harvesting system will be an alternative source of water at the campus and can be used for Laboratories in Civil and Mechanical Department, Washrooms, as well as for Horticulture and other Purposes. Present paper majorly focuses on Rooftop Rainwater Harvesting (RRWH) of the study area of Dr. Babasaheb Ambedkar College of Engineering & Research (DBACER) Campus, Wanadongri, Nagpur. The expected outcome of this study is the development of Rainwater Harvesting System for the catchment area of campus from Admin Building, CSE Department, Killa Building, Workshop Building and Mechanical Department. This study will fulfil the scarcity of water as our college campus lies within hilly region there is slightly greater demand of water than other areas.
