Overwhelmed capacities and (in the Alps at least), the water springs can't really be expanded to meet the increased population and/or industry and/or agriculture. And the decreasing amount of snowfall every year means that the natural reservoirs are not filled to their needed capacity in the spring.
And in the water bottle case, some water (I don't know how much really) is used as a component in plastic production and it's not really returned to nature
