There's a water treatment plant near the river where I grew up, and I remember watching the clean water flow out from a pipe into a small pond. It's not something people think about often, but the whole process of turning murky, polluted water into something you can drink is pretty amazing. The plant uses sand filters and huge settling tanks to remove dirt and bacteria, and it's staffed by operators who check the water quality every hour. It's not glamorous, but it keeps the city running.
