My grandparents lived 14 miles from the nearest “town” in southern Oregon. Their household water came from a spring not too far uphill. It fed into a large corrugated tank and went right into the house. It tasted good, they lived there for 30+ years before they died, and they never had any trouble with it. For irrigation (basically, just a large lawn and a good-sized flower garden) they pumped water from the creek.
