Design of Rooftop Rainwater Harvesting Structure in a University Campus

Abstract

Rain water harvesting (RWH) is an excellent technique of water conservation for future needs and also to recharge groundwater. Due to the alarming population burden, climate change, uneven distribution of rainfall and abrupt variation of meteorological parameters, the surface and ground water resources are continuously depleting in India. Hence adoption of different water conservation techniques at individual, institute and community level has become imperative to cater to the needs. This study was aimed at designing a rooftop rainwater harvesting structure for the Amity University Mumbai, located in Maharashtra state of India. Out of the possible catchment areas, the main building was selected as the required catchment area for rainwater harvesting considering the water demand in university campus and the supply. Further, different parts of the RWH system were designed based on standard guidelines It was observed from the analysis that implementation of RWH system in Amity University Mumbai campus can resolve the water scarcity problems during non-monsoon season by storing a huge quantity of 6109.42 m3 in a year in the university campus. This initiative can increase the water supply for construction work, gardening and also will help in artificial recharge of ground water thus enriching both the surface and the ground water resources.

Study on Potential and Practices of Rooftop Rainwater Harvesting System in Oxford College of Engineering and Management

“…The pipes include a gutter system made from longitudinally split polyethene pipe, which has a flushing system that allows the system to be flushed clean periodically. Therefore, people can save hundreds of dollars a year instead of buying the popular yet questionable quality water available in jars in the market from USD 0.35 to 1.3 per 20 liters and save between USD 51-85 each year (Mambretti & Melgarejo 2019). The general objective of the research was to evaluate the possibility of promoting rooftop rainwater harvesting to address future water scarcity at Oxford College of Engineering and Management.…”

The Potential of Rainwater Harvesting as an Optional Water Supply of Building XYZ

“…Rainwater harvesting is described as a technique of collecting water and storing it for the purpose of using it to avoid a shortage of usable water. According to Mishra S. et al (2020) when it comes to the conservation of water, rainwater harvesting is a good method for responding to meet the water demands of the community. When it comes to the problem of water shortage rainwater harvesting is an emerging countermeasure to respond to the effects of climate change (Lee et al, 2016).…”
