It's not difficult to drill a well and install a septic system in rural area. All houses in rural live on that. The subcontractor who work on installing the septic or drilling the well should be licened, otherwise, it is illegal and wouldn't get passed the inspection. For a well at 150 feet deep, the cost is around $5000, dependens on how deep it hit the rock and length of the steel casing they will use. Regarding the septic system, the cost depends on how big the house, how many bedrooms and bathroom. It also depends on the natural grade of your lot.
