If you want to make people stop using water bottles you have to improve the water going to their house.

I've been to very few places (in the US) that the water tasted good from the tap. One was a major metro, the others were places with well water.

My parents live in a medium sized Texas city that has tap water that is typically brown, sometimes it comes out of the tap foamy. Some filter it, but many just buy bottled.

I use a simple filter at home to improve taste. However, after living in hurricane and tornado prone areas, I keep a small supply of water on hand (a few cases of bottled) for emergencies.
