As for recycling wastewater, there is a low rate of sewer hookups in Taiwan (only about 10.8 % islandwide). Currently, only the cities of Taipei, Taichung, and Tainan have water treatment plants that can take water through a level two treatment process and then reuse it. Moreover, this water has limited uses, including cleaning streets and watering plants in parks.
至於生活污水的再生利用，由於台灣下水道普及率太低（全國平均為 10.8 %），目前僅有台北、台中、台南市的污水處理廠，將污水作二級處理後回收，而且只用在道路的清掃、公園綠地的澆灌等少數用途上。
