There is no average rate on well drilling, as they are typically billed on a per-foot basis. If a contractor has to drill through rock or other obstacles or hazards, the price goes up. Rates will vary by depth of drill, landscape, contractor rates, materials (like the actual pump), licenses, and labor and water testing regulations. If you drill a well, you are on the hook for testing the water. There are too many variables to know up front whether a well will cost $1,500 or $15,000. You have to speak to a licensed contractor who has the skill and expertise in drilling in your area to give you a realistic estimate.
