In my country (Brazil) buying bottled mineral water is also common. But I don't know whether it comes directly from the spring, or is passed through a filter first. We learn from childhood that one must only drink filtered or boiled water, so I won't be surprised if there's a filter involved.

Tap water is fine in most cities here but many people just prefer the taste. Not many buy it for drinking at home but it is very common in water coolers at offices.
