Each building at the institute has its own independent rainwater system. After the rainwater is collected via drains from the rooftops and balconies, it is sent to an underground storage tank. After passing through an aeration facility, it is used to water the lawns around the building.
校區各棟建築物也有各自獨立的雨水系統，雨水由屋頂露台及陽台排水溝收集後，輸送到建物地下的雨水收集槽，透過噴水設施，作為建築周圍的綠地澆灌水源。
