The only people who want to get off the water grid are largely ignorant, spoiled people who have never in their pampered lives, ever, EVER had to worry about their water supply, never mind walking miles with sticks and buckets over their shoulders to get water that is probably going to make you sick as hell unless you can treat and filter it, which takes time and money.
Our “water grid” is one of the greatest civilized and technological accomplishments of the 20th Century. You can go to nearly ANY water faucet ANYWHERE in this country and drink the water. It may not taste good.
But you can live on it. Boy, it will be interesting when everything goes down, how quickly these spoiled, snowflakes forget about their “off the grid” water stupidity.
They will find out that when there is no water, drinking it from a dung infested hoof print or petroleum contaminated tire rut will become an attractive option.
And everybody thinks I'm crazy for filling up soda and other plastic bottles with “good” water and a drop of bleach for storage.
