A Project Report on the Construction of a Rooftop Rainwater Harvesting System for a College

Abstract

In order to conserve water for the future and replenish groundwater supplies, rainwater harvesting (RWH) is a fantastic practise. Both surface and groundwater supplies in India are rapidly declining because of the country's burgeoning population, the effects of global warming, the inequitable distribution of rainfall, and the often-severe fluctuations in other meteorological indices. As a result, it's crucial that people everywhere start taking steps to conserve water on their own, in their schools, and in their neighbourhoods. The purpose of this research project was to create plans for a rainwater harvesting system on the roof of the Dhaanish Ahmed College of Engineering in Chennai, which is in the Indian state of Tamil Nadu. After analysing the water needs and available supplies on campus, the administration decided that the main building would provide the best catchment area for collecting rainwater for reuse. In addition, the RWH system's many components were developed using industry standards. Based on the results of the study, it was determined that if the RWH system were installed on the campus of the Dhaanish Ahmed College of Engineering in Chennai, it would be possible to store enough water over the course of a year to alleviate the College's water scarcity issues during the dry season. With this plan in place, there will be more water available for building and cultivation. It will assist artificially recharge groundwater, which will improve water quality in both the surface and subsurface. Dhaanish Ahmed College of Engineering, Padappai garden grounds and roof tops are included in the construction plan and implementation. Total roof surface area is 81706.38 square feet. IS 15797: 2008, "Indian Standards for Rooftop Rainwater Harvesting Guidelines," was used as inspiration for the design.
