Water is cheap/free because it's a physiological requirement for living, and not because it's abundant or is not a bottleneck. Price is not universal indicator

Water is cheap/free because it's a physiological requirement for living, and not because it's abundant or is not a bottleneck. Price is not universal indicator of value, neither being cheap implies that you can't run out of it. Many Indian cities are quickly running out of fresh ground water. The worst thing a city could do is let market determine the price so rich could use it more. Rationing at a less price is the way municipalities are going, which is more ethical way of doing things. The same could happen for energy or other resources, while they still being cheap.
