The lowest point of the grounds is near the front gate. With help from the parents, the school built a waterwheel here the size of a truck tire. It uses the energy from the stream water to make electricity. Every night it can light a three or four watt bulb for five hours.
校門口附近是全校地勢最低的地方，在學生家長協助下，校方在此建造一座水車，大小如同一只卡車輪胎，利用溪水作水力發電，每晚可供一盞 3 到 4 瓦的小燈泡照明 5 小時。
