I like how in the US Constitution, it is actually written in that we have INALIENABLE rights that we are basically born with because we are human beings. Of course, that doesn't mean that you get everything for free, but it just means that if someone is attempting to cruelly extort you for something, like water, that you absolutely cannot live without, that there could be cause there to fight the ill treatment legally. The fact that these are some of the first words in the US Constitution is something that might be able to be used against at least the current US government if it were to try something like this, but then other countries can look at this, too, because it proves that at least our initial government believed we had such inalienable rights. I guess what I'm trying to say is that this might have set some kind of precedence for this kind of thinking centuries ago.
As far as passing out water bottles, I think they were probably legally required to do that, because they are providing a paid service to people that they are otherwise unable to fulfill safely if they don't pass out bottled water or come up with some other fix. You're actively paying for a service that you cannot access and are not otherwise being comped on if they don't do something like pass out bottled water.
Our town had one of our water towers go bust due to the town not having it inspected properly and it rusted up. They had other functioning towers, but because of the way our system worked, if one was out, the water coming from the taps was not potable. So they trucked in bottled water but had it in those gigantic tanks outside the city hall for a while until they fixed the tank. It wasn't out of the goodness of their hearts.
I could be wrong with all of these things, but this is how I currently see it.
