FWIW, it is typical for anyone who lives outside of a city to have well water. I would be shocked if there were any regulatory issues with doing so anywhere in the US, or any issue with water rights. There are millions of people doing it right now.
I think hypothetically when the system is first installed it's supposed to be tested, but I don't put a lot of faith in that. Interestingly, in contrast to parent, it's pretty standard for the water to be totally unfiltered. Generally, you have an electric pump that cuts on any time the water pressure drops below a certain level to maintain it. Honestly I've no idea how much it costs me a month, but it's pretty nominal. My electric bill runs about $125/mo and most of that is the AC.
(In case you were wondering, sewer is dealt with via a septic system, which still amazes me. All your wastewater drains into a ~1000 gallon tank buried in the ground. At the top of the tank are field lines, which distribute water and drain it over a wide area. Solids are rapidly broken down by bacteria in the tank and quickly dissolve. These systems can be maintenance-free for 25 years, though the septic industry recommends you pump them every several years to remove "sludge" that slowly accumulates at the bottom.)
to get water from ground, drill a hole about an inch diameter so long pipe can be inserted.
if you can get good water within 9 meters, that's great because standard pump can suck up to 9 meter down.
if you get salty, rusty, smelly colored water, drill deeper. 30m is pretty much max depth for home-use jet pump and normally you get clean water.
you can get deeper too and use bigger hole too; however, that's when you need permit. industry and hotel often do because they need a lot of water very fast.
water collected from pump can be stored in large tank above roof. then gravity plays it part delivering tank-water.
there's a switch on the tank that cuts electricity to the pump when a buoy inside the tank float up to a certain level. so, my switch is simpler water-level-based, not pressure-based.
from empty to full, my pump runs about 30 min. my pump is 1 horse power or about 750w. so for a month that would be 30 * 30/60 * 750w = 11.25 kwh.
for disposals, my house get two lines. one for washing, bathing, etc and that goes to city sewer. another is for human waste that goes to house ground sewage tank.
sewage tank is basically an unsealed empty space inside ground. bacteria decompose human waste and the water just get filtered by ground beneath. the tank gets full over time and sewer tank service can come and suck the sewage tank.
