We dont have utility at my home. Our well water was unpleasant to drink. Had to refill two five gallon jugs every week. Lots of people in my area have to do that. The cost more than doubled in one year. Still much cheaper than pop, but drinking water seems like something that should be free to everyone.
Ive since installed a UV light filter and a five stage under the sink RO filter for a drinking water spigot in my home. My water tastes fantastic now, but it was an investment, required know-how, and needs twice annual maintenance.
Tldr: I understand why some folks still need to buy bottled water.
