This article proposes a plan that takes the original building roof of colleges and universities as an example. The "green roof rainwater collection and utilization system" is converted to achieve the "green roof" landscaping environment, insulation and insulation, and collecting water sources. It is mainly composed of two parts: "Green Roof" and "Rainwater Collection and Utilization System". Pingling waterproof layer, flexible protective layer), drainage water storage layer, filtering layer, light -quality synthetic planting soil, vegetation layer. The "rainwater collection and utilization system" section is to collect, treat and use rainwater in the process of purifying water quality, and use a unique "double -flow diameter, dual filtration, dual collection" to store rainwater. The rainwater of the indoor water storage tank is used to flush the toilet. The water tank is equipped with a water level sensor, which realizes the automatic switching of water tank water supply and municipal water supply to ensure continuous water supply. The water in the underground pond is used on ground irrigation vegetation and moist road surface.
