What happens with unfinished bottles of water on public gatherings?

I saw again Arsene Wenger open a water bottle and take one slurp and put the bottle away. It was probably the bottle provided by organizers.
The same goes for bottles on rock gigs, when singers or musicians take only couple of slurps...

So, what happens with that water?
Who drinks it or when do they pour it out?

Does it happen like with uneaten food - that it goes to the homeless or the rich organizers' dogs?

When you rinse something under a tap, what happens to that water then?

The water returns to the water cycle. I don't think there's much of an issue with water being wasted on that scale (except at certain crucial times and in certain troubled locations). The issues with water are whether there is enough of it long term for the expanding human population and whether we can afford to make enough it drinkable fast enough. There's no more or less water on earth now than there was 100 years ago, 1,000 years ago, 10,000 years ago. 100,000 years ago etc., although there may have been differing amounts of it 'stored' as ice at different times down through history.
