No. It’s not worth it. It saddens me that people would rather pay a ridiculous mark up on water than get mad and organized about the fact that they have undrinkable tap water. At the very least, won’t you consider filters, or refilling your gallon jugs for 40 cents each? Buying bottled water by the 500ml unit is wasteful and incredibly expensive. Consider that the daily recommended intake of water is ~2.5L for males and ~1.5L for women. If you and your wife were getting your daily recommended intake you’d be in the shit for sure.
4L per day = 1460L/year
$6.99 per 3L = ~$2.33/L
One year of the daily recommended intake of water for the two of you would cost $3401.80 plus tax and bottle deposit (if applicable). Does that not seem the least big INSANE to you? Not to mention the 2920 bottles the two of you would be casting away yearly.
Stop. Please stop. Water privatization is bad enough as it is. If your tap water sucks, get hopping mad. Water is essential for life. This is why we mandate that the government monitors it, ensures its suitability, and provides it to us at dirt cheap rates. If they are failing at that, you are a coward if you decide that you would rather drink bottled water than rock the boat, a fool if you willingly pay the roughly 100,000% markup, and an asshole as you recklessly cast away a few hundred to a few thousand empty bottles per year. Sorry to be harsh, but seriously, grow up.
