PBS Terra had an tour of this waste water processing plant along with other episodes on how it is to live at the McMurdo station. An interesting fact is food doesn't get spoiled there so you can keep it around for a long time.
Offtopic, but for how interesting, and likely expensive, that series was, I'm surprised by its relatively low view count. That video didn't even break a million! Compare that with, oh, this random 3Blue1Brown video [1] that has 1.5M views.
Unfortunately, I suspect it is proof that YouTube is not the place for high production value documentaries.
