storm drain

• When it rains , the water flows over these surfaces , picking up animal feces and other pollutants and washing them into drainage ditches or storm drains , many of which lead directly to urban lakes , coastal creeks or beach areas
  一旦下雨，流经这些地面的水流，就会连带将动物粪便及其他污染物冲刷到排水沟或雨水沟，而这些沟渠大部份又直通到都市内的湖泊、海岸溪流或海滩地区。
