Short answer, they don’t. Baldbear had the right of it. The upside of that is if you’re too far for sewer and water you’re also likely too far for an electrical grid. Which means that when you install your solar you don’t have to tie into that Grid in any energy you produce is yours to do with as you wish no continuing bills from corporations. Yes the initial cash outlay can be steep but over a lifetime the benefit is greater.
It’s not just high mountains, you know.
I live half a mile from a four-lane highway, seven miles from the town which serves as our county seat. A water line for the local water cooperative passes nearby, as does a high-pressure sewage line from the nearby elementary school. But I and all twenty or so of my neighbors use wells for our water and septic tanks for our waste.
There was talk at one time of tying us into the water line, but it would have cost each of us four or five thousand dollars. That idea went nowhere. As it is, our water tastes really good. No flouride or chlorine, just Nature.
My well is tucked behind my yard barn in the back yard. My water comes from right there in my yard, 80 to 100 feet down. My septic tank is buried in the front yard, with four “manholes” to access various parts of the tank and its associated pump. The leach field for my septic system is a ways off in the side yard.
I had to have the well’s pump replaced after 40 years of service, and once I had to have a pressure regualtor valve replaced. Other than that, I ignore it. I have the septic tank pumped out every three to five years. Every three months, I change a pipe connectionon the leach field to change the drainage pattern; the same day I clean the plastic filter that lies between the septic tank and its pump.
Remote homes and even nearby rural homes often use a septic tank system, right on the property, for sewer and waste disposal.
Rural homes often use a drilled well system.
If the home is remote enough without good access to a well they can use a rainwater catchment system with a cistern (big water storage) and possible chlorine / bleach system to purify the water.
It’s the other way around, Mountain provide water to the land.
Water “come” from mountains, most rivers in the world find it’s source in a mountain. If they don’t have a source of water then they have a “glacier” (if they don’t have either it’s a hill not a mountain)
As for sewage gravity bring it down. How ? depends on the infrastructure
watched a vid, house built on the side of a mountain and was also lake front.
They had septic but also needed to pump higher up the mountain so the liquid would have more time to be filtered from the soil.
They were too close to the lake and it would pollute it if released near their septic.
Dont recall what they did for water but they had tapped into a stream for hydroelectric for cloudy days along with solar and batteries so im guessing thats where their water came from. Makes sense to do it this way as the infrastructure is there, why add the expense of drilling. Obviously they need a filter/reverse osmosis etc
Its not logical to connect to the grid in some of these situations, it could be 10k + just to get electricity to the house/cabin. Pumping up hill means you loose a lot of pressure so rain water collection/well/stream plus filters is a more viable solution. Then septic/open air/compost for toilet. You can search for each of these individually, plenty of text, images and videos, its pretty fascinating
