That day, I came back in the restroom to wash their hands, found the tap is out of order, a clear water like a waterfall flowing, I had thought to turn it off, but can't get it, turn the tap off.

当天，我在洗手间洗手回来，发现那里的水龙头坏了，一滴滴清澈的自来水像瀑布一样往外流，我费劲心思想把它关了，但是总不能如愿以尝，将水龙头给关掉。

For example, most of the reject water generated within the UPW system is re-circulated or re-used for back wash or other users.

例如，大部分由超纯水系统产生的废水会重新流动到后期水洗过程中，或者重新用于其他用途。
