Water consumption in malls, particularly in restrooms, contributes significantly to excessive freshwater use. This project aims to implement an efficient rainwater harvesting system for toilet flushing to reduce reliance on municipal water completely. The issue is the waste of potable water for non-drinking purposes. Our solution collects rainwater from rooftops, filters it through multimedia filter and activated carbon filter, and stores it in a reservoir for flushing. The working model shows how this whole process works for non-potable use. This study highlights how rainwater harvesting can promote sustainability and lower operational costs in commercial spaces
