Vanguard World Toilet Crisis was the documentary shot in 2010, that I was thinking of. I'm afraid to look at the newer one you provided. The 2010 docu. had the host/narrator out in a rowboat gagging and puking and gagging some more from the stench, and lots of people taking dumps in the open. Oh well, I have to watch it now, just so my knowledge isn't all based on hearsay and Fordish-like nonsense.
I saw a video on the history of the toilet a few weeks ago. It showed how so many people in the world don’t even have rudimentary facilities. It was an interesting video.
