Survivor (Not a spoiler)

But rather a question:

It's pretty obvious this season since they had the heat stroke challenge a couple of weeks ago that the tribes are carrying a 5 gallon container of water to each challenge. There have been several shots of either one person carrying the water while walking to the challenge or more common - two people with the water can hanging from a pole.

I am assuming that this is a Survivor 'rule change' or at least something where the tribes were provided with the water cans and instructed to bring them to the challenges. All in the hope of avoiding the heat stroke thing. That all makes sense.

What I want to know: Did they carry water to challenges last season in the Fan Favorite show? Since this BBB season was filmed before the FF, it would make sense that they would have done the water thing - but I just can't remember. Anybody recall seeing the water container brought to challenges?
