Water is very local. Our water comes from springs about 3 miles away and is hard. On the whole it is not chlorinated unless the natural flow has been diluted by heavy rains (i.e. it hasn't had chance to filter through the rocks.
Straight from the supply our water doesn't taste very nice. What we have is a water softener and then the softened water passes though a three stage filter which then makes it reasonably palatable.
When we visited SWMBO's cousin in Barcelona - the water, as far as we were concerned, was undrinkable so we used bottled water.
