Quick Answer
Well drilling costs $25 to $65 per foot, with most residential wells totaling $5,000 to $20,000 depending on depth and local geology.
Depth is the primary cost driver, and depth itself depends entirely on local geology — how far down you need to drill before hitting a productive aquifer. This is why legitimate drillers quote per foot rather than a flat total: they cannot know the exact depth until drilling begins.
Checking your county's public well log database for nearby properties is the single best free way to estimate likely depth and cost before you commit to land without an existing well.
Well Drilling Cost by Depth
Cost scales directly with depth — and depth varies enormously by region and geology.
| Depth Range | Typical Total Cost | When This Applies |
|---|---|---|
| 100 – 150 ft (shallow) | $2,500 – $9,750 | Common in areas with a high water table. Minimum depth for most drinking water wells. |
| 150 – 300 ft (typical) | $3,750 – $19,500 | Most common residential depth range across the U.S. Cost varies significantly by regional geology. |
| 300 – 500 ft (deep) | $7,500 – $32,500 | Required in areas with lower water tables or where shallower drilling does not produce adequate yield. |
| 500+ ft (very deep) | $12,500 – $50,000+ | Needed in challenging geology (bedrock, desert regions) where water is only found at significant depth. |

What GPM Yield Actually Means for Your Budget
Gallons per minute (GPM) measures how much water your well can sustainably produce — and low yield adds equipment cost.
| Yield (GPM) | What It Means |
|---|---|
| Under 3 GPM | Below most code minimums for full-time residential use; usually requires a storage tank and booster pump ($2,000-$5,000 extra). |
| 3 GPM | Minimum sustained yield required by most household building codes for single-family use. |
| 5 – 10 GPM | Comfortable range for a typical household — covers normal daily use without storage equipment. |
| Above 10 GPM | Strong yield with capacity for irrigation, livestock, or a large household in addition to normal use. |
What Drives Well Drilling Cost
Beyond depth, these six factors shape your total project cost.
Drilling through soft soil is faster and cheaper than drilling through bedrock or rocky terrain. This is the single biggest reason per-foot pricing varies so widely by region — from roughly $15/ft in some areas to $65/ft in challenging terrain.
Drillers price per foot because they genuinely cannot know exact depth until they hit water. Be cautious of any contractor quoting a flat total price without first assessing local well logs or geology.
Well casing (steel or PVC) protects the borehole and prevents contamination. Casing material, diameter, and depth all factor into total material cost.
Submersible pumps for deeper wells typically run $1,500-$3,000 installed. Jet pumps for shallower wells (under 100 ft) are less expensive but also less powerful.
Post-drilling water testing costs $100-$650. If contaminants are found, treatment systems (filtration, UV purification, reverse osmosis) add $500-$5,000 depending on what is needed.
Well permits range from $5-$1,880 depending on jurisdiction. Remote sites requiring new access roads or pipeline runs to the house add further cost beyond the drilling itself.
Regional Geology Drives the Biggest Cost Swings
The same well depth can cost dramatically different amounts depending on what the drill bit has to pass through. Soft soil in much of the Southeast and Midwest drills faster and cheaper than the bedrock common in parts of the Northeast, or the deep water tables found in desert regions of the Southwest.
This regional variation is exactly why a national average is only a starting point — local driller estimates based on your specific address are far more reliable.
Also evaluating a septic system?
Well and septic costs are typically planned together on rural land.
See Septic Cost →How to Prepare Before You Drill
Whether you are evaluating land before purchase or planning a well for a lot you already own, a little research upfront prevents major budget surprises.
Most counties maintain free public records of nearby wells, showing depth and yield (GPM) for properties in the area. This is the single best free data point for budgeting before you own the land.
Local well drillers know the geology in your specific area better than any national average. A quick call to 2-3 licensed drillers can give you a realistic depth and cost range before you commit to land.
Legitimate drillers quote per foot because they cannot know depth until they hit a productive aquifer. A flat total price quoted without site-specific geology data is a red flag.
Water quality (bacteria, arsenic, radon in bedrock areas) varies even within the same neighborhood. Do not assume your well water will be drinking-quality without testing.
Most drillers charge for actual work completed, with some offering reduced rates if a hole does not produce adequate water (a "dry hole"). Confirm this policy in writing before drilling begins.

Frequently Asked Questions
How much does it cost to drill a well?
Well drilling typically costs $25 to $65 per foot, or $1,800 to $24,500 total, with a national average around $5,500 to $7,500. Total cost depends primarily on depth, which varies by local geology, and can range from under $5,000 in shallow-water areas to over $20,000 in challenging terrain.
How deep does a well need to be?
Wells for drinking water should be at least 100 feet deep, but actual required depth depends entirely on local geology and where a productive aquifer is found. Most residential wells fall between 150 and 300 feet, though some areas require drilling well past 500 feet.
What is a good GPM for a residential well?
Most building codes require a minimum sustained yield of 3 gallons per minute (GPM) for single-family use. 5-10 GPM is comfortable for typical household needs, while above 10 GPM provides extra capacity for irrigation or livestock.
Is it worth drilling a well instead of connecting to city water?
For properties where municipal connection costs exceed $10,000-$15,000 (common in rural areas), a private well is usually the better long-term financial choice. Wells typically pay for themselves in 5-10 years through eliminated water bills, especially for high-usage households.
How do I estimate well drilling cost before buying rural land?
Check your county's public well log database for depth and yield data on nearby properties — most states maintain these records for free. Calling 2-3 local well drillers for a regional estimate based on the property address is also a reliable, low-cost way to budget before purchase.
What additional costs come with well installation beyond drilling?
Budget for a pump ($1,500-$3,000 installed), water testing ($100-$650), potential treatment systems if contaminants are found ($500-$5,000), permits ($5-$1,880 depending on jurisdiction), and a storage tank if yield is below 3 GPM ($500-$3,000).
