Assessing the potential of rainwater harvesting and reuse for sustainable university campus

Abstract

Water resource management, one of the paradigms for creating sustainable universities, ensures that universities manage the quantity of water used and maintain the quality. Water resource management models that begin with campus priority create input for cities at a higher scale. Water resource management encompasses a variety of sustainable practices. One of the most applicable is the reuse of rainwater. The study aims to propose site-specific solutions for reusing harvested rainwater and contribute to nature and the water cycle. In the study, the Rational Method was used to calculate the amount of rainwater. Hardscape (roads, parking lots), landscaped areas (landscaped and wooded areas) and roofing materials within the campus were determined and the amount of rainwater was calculated for each material. In a year, the total water consumption was calculated at 54,773,000 liters. The valuable volume of annual rainwater is 296,400,000. It can be seen that a volume that is approximately 5 times the amount of water required is achieved.
