Well Drilling Cost: What You'll Actually Pay

By Andrea · August 2026

Drilling a private water well is one of the larger investments a homeowner makes on their property — and the price range is wide enough that vague averages don't help much. This guide breaks down what drives the cost, what typical ranges look like by depth, and what you'll need beyond the drill rig before water reaches your tap. All figures are estimates as of 2026 and vary by region, geology, depth, and contractor. Get at least three quotes from licensed local well drillers before committing.

What Drives Well Drilling Cost

Depth is the single biggest variable. Drillers charge per foot, so a well that hits water at 80 feet costs a fraction of one that needs to go 400 feet. But depth isn't the only lever:

• Geology and rock type — drilling through solid granite or fractured bedrock takes longer and wears through more equipment than soft soil or sand. Hard rock typically adds cost per foot.
• Casing diameter and material — most residential wells use 6-inch steel or PVC casing. Larger diameters, or situations requiring steel where PVC would otherwise work, push costs up.
• Grouting requirements — many states mandate grouting (cement or bentonite) around the upper casing to prevent surface contamination from migrating down. Required length varies by state.
• Permits and well logs — most counties require a permit before drilling and a driller's log after. Fees range from nominal to several hundred dollars depending on jurisdiction.
• Region — labor rates, equipment mobilization, and local demand all vary. Rural areas may have lower labor costs but higher mobilization fees if the driller is traveling far.

Cost Per Foot and Total by Depth

Most residential well drillers quote a per-foot rate that covers drilling, casing, and basic development. Pump, pressure tank, electrical, and wellhead are typically separate line items. Per-foot rates generally fall in the range of $25–$65 for straightforward conditions; hard rock or remote sites push toward $80–$100+ per foot. Here's how that math plays out at common residential depths:

• 50–100 feet (shallow to moderate): common where the water table is high — parts of the Southeast, Pacific Northwest, and Great Lakes region. Total drilling cost at this depth tends to stay on the lower end of the residential range.
• 100–200 feet: the most common range for drilled wells across much of the U.S. Mid-range per-foot costs apply. Budget more if the driller hits hard rock before the target depth.
• 200–400 feet: necessary in areas with deep aquifers — parts of the Midwest, Southwest, and New England granite terrain. Costs scale significantly; this is where the per-foot rate matters most.
• 400+ feet: deep wells for areas with very low water tables or confined aquifers. Rarely the first choice; costs can reach five figures for drilling alone before pump and system components.

Example (estimate only, not a quote): a 200-foot well at $45/foot runs $9,000 for drilling and casing alone. Add pump, pressure tank, electrical hookup, wellhead, and permit, and total installed system cost commonly lands between $12,000 and $18,000 depending on region and system specs.

Beyond the Drill: What a Complete Well System Costs

The hole in the ground is just the start. A working well system needs a pump, a pressure tank, electrical service to the pump, a wellhead or well cap, and piping to the house. Each adds to the total.

Most drilled residential wells use a submersible pump suspended in the casing; shallow wells within 25 feet of the surface may use an above-ground jet pump instead. Pump type, horsepower, and sizing depend on well depth and household demand. See the full breakdown at Submersible Well Pump Cost and Shallow Well Pump Cost.

A Pressure Tank is the other non-optional component. It holds a pressurized air cushion that lets the pump run in longer, less frequent cycles — without it, the pump short-cycles every time you open a tap and burns out fast. Size matters: an undersized tank stresses the pump even if the tank itself is new.

Pump installation — setting the unit, running the drop pipe, and wiring the control box — is a separate labor cost from drilling. For what to budget, see Well Pump Installation Cost.

Shallow Well vs. Deep Well: Which One Do You Need?

The distinction isn't arbitrary — it's physics. Shallow wells (generally under 50 feet, sometimes classified as under 25 feet for pump purposes) reach near-surface groundwater. They're simpler to drill and less expensive, but more exposed to surface contamination from agricultural runoff, septic systems, and flooding. Deep drilled wells access aquifers well below the surface, offering better natural protection and more reliable yield — at higher drilling cost.

Where the water table sits on your property is something only a licensed local driller can estimate with confidence — and even then, no one guarantees hitting water at a specific depth. Neighboring well logs (often on file with your county health department) give a reasonable starting point for depth expectations in your area.

Artesian and Geothermal Wells: Different Animals

An artesian well taps a confined aquifer under natural pressure, sometimes eliminating the need for a pump entirely. These wells typically go deeper and require pressure-rated wellheads, affecting total cost. Full details at Artesian Well Cost.

Geothermal wells are drilled for ground-source heat exchange, not water supply — the cost structure, depth, and drilling method differ significantly from domestic wells. See Cost Of Drilling A Geothermal Well for what to expect.

Ongoing Costs: Testing, Repairs, and Replacements

Private well ownership means the upkeep is yours. Three recurring costs catch homeowners off guard.

Water quality testing is required annually for private wells — the EPA recommends testing for bacteria and nitrates at minimum, with additional tests depending on local geology. Costs range from under $30 for a basic screen to several hundred for a full panel. See Well Water Testing Cost for what to test and what it runs.

Submersible pumps typically last 10–15 years; smaller components like pressure switches and foot valves fail more often and cost far less to fix than a full pump pull. For common repairs and what they run, see Well Pump Repair Cost.

When a submersible motor fails past its useful life, the pump must be pulled and replaced — a job that scales significantly with depth. Full cost breakdown at Well Pump Replacement Cost.

How to Get an Accurate Quote

Get three quotes from licensed local well drillers — not general contractors or online estimate tools. Give each driller the same inputs: property address, any neighbor well depth data, intended use (drinking water, irrigation, or other), and whether pump and electrical should be included in the bid or quoted separately.

Check licensing through your state's well contractor licensing board before anyone drives a rig onto your property. Ask whether permit fees are included in the quoted price or billed separately. And confirm whether the per-foot rate is fixed or subject to upcharge if they hit unexpected rock — the answer matters a lot when geology is uncertain.

No driller can guarantee hitting water at a specific depth or a specific yield. If anyone promises otherwise, that's a red flag. What you're paying for is professional skill, proper equipment, and a well drilled to your state's construction standards.
