My home city ranks near the top of any "best tasting drinking water" poll I've seen, and people still complain and buy bottled water. It's ridiculous.
The vast majority of citizens in the US are served by perfectly serviceable potable water they just turn their noses up at it.
The individual has little to no control over the water or pipes that runs the water to their home. It is a take it or leave it situation. If you own your home, then you might be able to install a water filtration system. This might be at the very least $200+. Okay. That doesn't compete with the price of bottled water. What about just a water filter pitcher? $30+. Well, now that's far more reasonable, but still represents 20-30 cases of water.
Bottled water IS the cheap, easy option. Should people fight and vote for infrastructure improvements so that they have clean, good tasting water? absolutely. But while we're working on that, we'll drink bottled water.
We were living away from our home (and water filter) for a few months and bought the cheapest bottled water we could. It was $1 per gallon. Where is this magical bottled water plant that 60 gallons of water for $1.
I am, however, going to disagree with how much water. 2 gallons of water for a single person each day seems to be more than just excessive for drinking water. Even if I was drinking 17oz each primary meal and another upon waking and upon going to sleep, that still leaves 171 oz remaining to reach 2 gallons.
We use an RO filter, provides amazing taste.
I'll buy a bottle of water and vote.
Where I live it happens to taste fine but my relatives live off well water and I always pack a case of water when visiting.
