It's called a fact. Just repeat it out loud. You can buy your water in drums as well as by a monthly subscription. You can distill your tapwater. You can drill a well and take your chances with groundwater. I guess you don't like freedom very well, since it is so demanding and inconvenient.

There are people who are not connected to a municipal water supply. Do they die of thirst? No. They have starch in their souls and they get the job done, because it won't get done by bitching. (My wife has to purchase her water supply in bulk because her borehole went dry. There is basically no municipal water supply in Lusaka. Cry me a bucket.)
