    It'll be cleaned and reused.

    Our toilet water goes into the same place as our tap water and the "waste" is just filtered out and the water is sterilized and stuff. (At least, that's what I've been told happens.) no point wasting water.

    I remember doing this for GCSEs.

    There's lots of tanks to let all the solids settle. Then theres tons of filtration then chlorine and that's it.

    I never really understood how the soluble impurities are removed though.

    Let's say you flush the toilet - there's loads of wee in there. That won't be filtered out (I presume) and even if you add chlorine - it's still wee. It's just got a bit of bleach in it.

    One crazy thing is that I read stupid hipsters in Seattle etc are paying big money to drink "raw" water - i.e. untreated water. Morons.

    Probably to do with dispersal and sterility. First, most piss is sterile anyway. Second, the amount of piss per se leaving a treatment plant to go back to environment is small. The blackwater treated from sewage isn't pumped straight back into water tanks, it's pumped to rivers etc, so the dispersal rate of that relatively small amount of piss is big. The real nasties are killed or removed in the treatment process (not just chlorine, also aeration etc).

    The usual thing in the UK is for it to be piped to a wastewater treatment plant along with the rest of the sewage

    most of the clever stuff at the wastewater treatment plant is done by naturally occurring aerobic bacteria... which the plant is designed to encourage.

    So like we shower with water that contains wee? What's the point of showering then? :hmmm:

    The water pumped back to environment from a sewage plant goes through the entire natural water cycle again. Natural water is then collected and treated again before it gets to you at home. There will be very little piss - if any at all - in your shower water.
