I think water meters serve 2 purposes. One being that it makes you more aware of the water you might waste as there is always a sense of "having to pay for it" and the second being that single people and/or couples are not having to pay for water they do not use based on an average for the size of the property.
I think I am right in saying that all new build properties automatically have water meters installed.
Sounds a bit like the North East coast Bags we never suffer from water shortages.
