Water from a river or lake may travel to a treatment plant. First, a mesh removes large objects. Other steps help small particles come together and sink.
The water passes through a filter. Then workers disinfect it to reduce harmful germs. They take a test sample and check water quality.
Clean water travels through a pipe to your tap. The exact process depends on the water source. “Clear” does not always mean safe to drink, so public systems test it often.

Chinese translation
来自河流或湖泊的水可能被送到自来水厂。首先，滤网拦下较大的杂物。接下来的工序让细小颗粒聚在一起，沉到水底。
水经过过滤，然后由工作人员消毒，减少有害微生物。他们还会取水样，检查水质。
处理后的水沿管道来到你家的水龙头。具体工序取决于水源。水看起来清澈，不一定就能安全饮用，所以公共供水系统需要定期检测。

Background notes (Chinese)
常见的自来水处理包括混凝、沉淀、过滤和消毒，但不同地区和水源的工序会有所差异。除了水厂处理，输水管道、蓄水设施的管理及定期水质检测，也共同保障供水安全。
