只要打个电话，洗车工就骑着三轮车，载着水箱、水管、高压喷枪、清洗剂、毛巾等洗车工具应约而来。

Once you make a call, the washer will come to your house on a tricycle, carrying a water tank, a water pipe, a high-pressure spray gun, cleaning agents and towels.

典型的解决方法是建造更大直径的排水管和巨大的地下水箱来容纳过量的来水，直至下水管网能够自行处理水流。

The typical solution is for a city to build larger pipes and a giant underground tank to hold the excess water until sewers can handle the flow.

由于它和排水管一样有一个弯道，里面就存有一些水把虫子挡在水箱外面。

Since it has a curve like a drain pipe, water will get caught there and keep bugs from getting into the tank.
