Go watch the original video - it's freely available on YouTube:

I watched it, and he seems to be basically saying that water should have a value or price. And that for those who don't have access to it, we need to take steps to address that.
I don't see anything controversial about that - fresh water isn't free and it damn as hell is a limited resource. We in our comfortable Western lifestyles definitely use too much of it, so I'm not sure why it shouldn't have a price.
Nowhere in that video does he claim we should somehow go into random third world countries and steal their water - which is what this meme somehow seems to have transformed into.
Anyway, if you want to read the other side (obviously from their perspective):

From the Nestle website you linked and subsequent articles and interviews Brabeck seems to have backtracked and now states he believes a minimum amount of water is a human right. He still wants water privatisation though, and must have his shareholders first in mind as CEO of Nestle, not public interest.
