I'm almost positive my uncle is also on a community well, if not his own personally well. There's no outside major pipe line going into the mountains there.
OK, but I've actually lived where I've been on spring water with a sewage connection, and where I've been on well water without one and using septic, and meanwhile I had to get internet via a local WISP. So while the water and sewage needs can sometimes be handled locally, the internet needs cannot and never can be by definition. But also, the internet is much easier to bring in, I can't reasonably send water through the air (though it does arrive that way sometimes) and I certainly don't want to airmail my sewage.
In some scenarios, your best bet would be more cell towers or satellite, especially if the alternative is attempting to blast or bore through rock.
That's really important to Morlocks, but not so much for the rest of us.
