I grew up out in the sticks. We had some city-slickers move into the house down the road (we would have been neighbors, but there was a field between us). After a few days, they called my dad for help with a plumbing issue. They didn’t have any water. They had run out of water.
Our area didn’t have municipal water lines, so every house had big tanks buried nearby, and had to get water delivered by truck.
They didn’t realize that when they bought the house



















Hmm. I don’t remember ever cleaning them…
But they definitely just thought they had city water. They were also v surprised to learn they needed to get their septic tank pumped. Presumably they thought they had city sewage as well
