Several years ago I lived across the street of a store selling revitalized water. They had an impressive machine with massive tanks and pipes in the store (which probably did the "revitalising") and an even more impressive amount of customers coming with bottle cases and big jerrycans...
The highlight of our weekend was the breakfeast on saturday morning looking at those people paying through their nose for tap water ;)
My parents bought a machine like that. I never understood it.
