It's a topic we'd rather not think about, where does last nights dinner go when we flush it down the drain? While you may already be grossed out just thinking about it, this question leads way to a significant subset of civil engineering and a massive amount of public funding. This video has been updated! Watch the updated version here: Just like all dogs go to heaven, all drains in a city lead to a wastewater treatment plant where that wastewater gets turned back into water that we can drink. Now, you may be thinking that you'd rather just let bygones be bygones and not think about this nasty part of real life, but here's the thing. Chances you've drunk water that was waste at some point... So, you might want to take some time to understand the engineering process that makes dirty water, clean.
