Quick answer:
Drilling a residential water well costs $25 to $65 per foot for the drilling itself, and $3,750 to $15,600 total for a complete system including casing, pump, pressure tank, electrical hookup, and permit — based on the national average depth of 150 feet. Most homeowners pay between $5,500 and $12,000 all-in for a standard drilled well. The number that matters is the all-in cost, not the per-foot drilling rate — those two numbers frequently look very different, which is where homeowners get surprised at closing.
At a Glance: Well Drilling Costs in 2026
| Scenario | Typical Total Cost |
|---|---|
| Shallow well (50 to 100 feet, soft soil) | $3,000 to $7,500 |
| Standard residential well (100 to 200 feet) | $5,500 to $12,000 |
| Moderate-depth well (200 to 300 feet) | $10,000 to $18,000 |
| Deep well (300 to 500 feet) | $15,000 to $30,000 |
| Very deep or hard rock well (500+ feet) | $25,000 to $50,000+ |
All costs above are complete system costs including casing, pump, pressure tank, electrical, permit, and initial water test. Drilling-only quotes will be 40 to 60 percent of these figures.
How Well Drilling Is Priced
Well drilling contractors price work in one of two ways and understanding the difference is the single most important thing you can do before getting quotes.
Per-foot pricing is the most common method. The contractor charges a rate per foot of drilling depth. National rates in 2026 run $25 to $65 per foot for a complete well installation, or $15 to $30 per foot for drilling only. A 150-foot well at $50 per foot costs $7,500 in drilling. A 300-foot well at the same rate costs $15,000.
Turnkey pricing is a single all-inclusive price for a working well system — drilling, casing, pump, pressure tank, electrical connection, permit, and initial water test. Turnkey quotes are easier to compare and have fewer surprises at the end of the project.
The critical issue with per-foot quotes is that they rarely include everything. A quote of $40 per foot for a 200-foot well is $8,000. Add casing ($6 to $11 per foot for PVC over 200 feet = $1,200 to $2,200), a submersible pump ($800 to $1,800), pressure tank ($600 to $1,500), electrical hookup ($1,000 to $3,000), permit ($100 to $500), and water test ($150 to $400) and that $8,000 quote becomes $11,850 to $17,400 before you get water from a faucet.
Always request a turnkey quote showing every line item. When contractors provide only a per-foot rate, ask them to specify what is and is not included. Get that in writing before any work begins.
Cost by Depth
Depth is the primary driver of drilling cost because you pay for every foot, and the deeper you go the more casing, wire, and pipe the system requires.
| Depth | Drilling Only ($40/ft avg) | Complete System Estimate |
|---|---|---|
| 50 feet | $2,000 | $5,500 to $7,500 |
| 100 feet | $4,000 | $7,000 to $10,000 |
| 150 feet | $6,000 | $9,000 to $13,000 |
| 200 feet | $8,000 | $11,000 to $16,000 |
| 300 feet | $12,000 | $16,000 to $22,000 |
| 400 feet | $16,000 | $21,000 to $30,000 |
| 500 feet | $20,000 | $26,000 to $38,000 |
The fixed costs (pump, pressure tank, electrical) remain roughly the same regardless of depth. The variable costs (drilling footage, casing length, pump wire length, drop pipe length) increase linearly with depth. This is why deeper wells cost disproportionately more — every additional foot adds not just drilling cost but casing, wire, and pipe cost simultaneously.
What Determines Your Well Depth
You cannot choose your well depth the way you choose a countertop. Depth is determined by where the water is.
The local water table is the most direct determinant. In areas with shallow water tables — portions of the Southeast, Mid-Atlantic coastal plain, and Midwest river valleys — wells may reach usable water at 50 to 100 feet. In the arid Southwest, Mountain West, and parts of New England with deep bedrock aquifers, wells of 300 to 600 feet are common. Your contractor can pull well log records from state databases showing what depth neighboring properties reached water.
Aquifer type affects both depth and reliability. Shallow unconfined aquifers are closer to the surface but more vulnerable to drought and surface contamination. Deep confined aquifers require more drilling but produce more stable water supplies year-round. See the complete well guide for a full explanation of aquifer types and how they affect your well.
Required yield affects depth. The FHA minimum for a residential well is 3 gallons per minute. Most families of four want 5 GPM or more. If the first water-bearing zone the driller encounters produces only 1 GPM, the driller will typically continue deeper to find a more productive zone, adding cost.
The dry hole risk is real. A driller charges per foot regardless of whether they find water. In some geologies, reaching water is nearly certain within a predictable depth range. In others — notably fractured granite in New England — neighboring properties can have very different depths and yields. Ask your driller what the dry hole risk looks like for your specific area and what happens financially if adequate water is not found.
Cost by Geology: The Factor Most Quotes Do Not Explain
The type of rock and soil your driller encounters affects cost more than almost any other variable and is the one least discussed in quotes.
| Formation Type | Per-Foot Drilling Cost | Why |
|---|---|---|
| Soft soil, sand, gravel | $15 to $35/ft | Drills quickly, minimal equipment wear |
| Clay and unconsolidated sediment | $25 to $45/ft | Slower, requires mud rotary drilling method |
| Sedimentary rock (sandstone, limestone) | $35 to $55/ft | Moderate hardness, some equipment wear |
| Fractured granite, gneiss, schist | $45 to $65/ft | Requires air rotary rig, rapid bit wear |
| Dense basalt or quartzite | $55 to $85/ft | Hardest formations, slowest progress |
A 200-foot well in soft sandy soil at $25 per foot costs $5,000 in drilling. The same 200-foot well in granite at $65 per foot costs $13,000. The driller does not know with certainty what they will encounter below the first 20 feet. If the quote includes language about rate changes at certain depths or for certain formation types, read it carefully. Some contractors use tiered pricing — one rate for the first 100 feet, a higher rate beyond that.
Air rotary vs. mud rotary drilling: The two main drilling methods have different cost profiles. Mud rotary drilling uses a drilling fluid to stabilize the borehole and works best in unconsolidated soils. Air rotary drilling uses compressed air and works best in hard rock. If your area has fractured bedrock, expect air rotary pricing. Ask the contractor which method they plan to use and why.
The Complete System Cost Breakdown
The drilling footage is only part of what you are buying. A working well system includes all of the following, and you need to understand which are included in any quote you receive.
| Component | Typical Cost | Notes |
|---|---|---|
| Drilling (150-foot example at $40/ft) | $6,000 | Varies with depth and geology |
| PVC casing | $900 to $1,650 | $6 to $11/ft over 150 feet |
| Steel casing (if required) | $4,500 to $19,500 | $30 to $130/ft — bedrock wells only |
| Well screen | $100 to $300 | Required in sand/gravel aquifers |
| Grout seal (sanitary seal) | $300 to $600 | Cementing the annular space around casing |
| Well development | $200 to $500 | Flushing and surging the well post-drilling |
| Submersible pump (1/2 to 1 HP) | $800 to $1,800 | Installed in the well below the water level |
| Drop pipe and wire | $200 to $600 | Increases with depth |
| Pitless adapter | $100 to $300 | The underground well-to-house connection |
| Pressure tank (20 to 44 gallon) | $600 to $1,500 | See pressure tank cost guide |
| Pressure switch and gauge | $100 to $250 | Usually included with pressure tank installation |
| Electrical hookup (230V circuit) | $1,000 to $3,000 | Run from breaker panel to well |
| Permit | $100 to $500 | Mandatory in most states |
| Water quality test | $150 to $400 | Required before first use |
| Total complete system | $10,550 to $31,400 | Wide range reflects depth, geology, location |
Most homeowners at average depth (150 feet) in average geology land between $8,000 and $15,000 for a complete working system. Wells in hard rock, deep aquifer areas, or high-labor-cost regions should be budgeted at $15,000 to $25,000.
Regional Cost Differences
Well drilling costs vary by 30 to 50 percent across the United States primarily because of differences in typical well depth, local geology, and labor rates.
| Region | Typical Depth | Per-Foot Rate | Complete System Range |
|---|---|---|---|
| Southeast (MS, AL, GA, FL shallow) | 50 to 150 ft | $25 to $40/ft | $4,000 to $10,000 |
| Midwest (IL, IN, OH, IA, MO) | 100 to 200 ft | $28 to $45/ft | $6,000 to $13,000 |
| Mid-Atlantic (PA, MD, VA, NY) | 100 to 300 ft | $30 to $55/ft | $7,000 to $18,000 |
| New England (ME, VT, NH, MA, CT) | 150 to 400 ft | $35 to $65/ft | $9,000 to $22,000 |
| Southwest (AZ, NM, NV) | 200 to 500 ft | $35 to $60/ft | $12,000 to $28,000 |
| Mountain West (CO, WY, MT, ID) | 150 to 400 ft | $35 to $65/ft | $10,000 to $25,000 |
| Texas | 160 to 600 ft | $30 to $55/ft | $9,000 to $22,000 |
| California | 100 to 700 ft | $35 to $100/ft | $15,000 to $50,000+ |
| Pacific Northwest (WA, OR) | 100 to 300 ft | $30 to $55/ft | $8,000 to $20,000 |
California is the most expensive state for well drilling due to deeper water tables in many areas, hard rock geology requiring specialized equipment, stricter permitting, and higher labor costs. Mississippi, Arkansas, and Louisiana are the most affordable due to shallow water tables and soft alluvial soil. Northeast states are expensive primarily because of bedrock depth and granite geology that requires air rotary drilling at premium per-foot rates.
Labor cost variation within regions is also significant. A well drilled in suburban New Jersey costs more in labor than the same well in rural West Virginia even within the same geological context. Get quotes from local licensed contractors, not national averages.
What Is Included in a Quote (and What Is Not)
This is where most homeowners get surprised. Read every quote carefully for these common exclusions.
Usually included in full-service or turnkey quotes:
- Drilling footage and rig mobilization
- Casing and grout seal
- Well development (flushing and testing yield)
- Permit application
- Pump installation
- Pressure tank
- Basic electrical connection from pump to pressure tank
- Initial flow rate documentation
Often not included — ask specifically:
Electrical panel to well circuit: Many quotes include connecting the pump controls to a junction box near the well, but the 230V circuit from your main electrical panel to the well may be a separate electrician cost. This runs $500 to $2,500 depending on the distance from the panel to the well.
Water treatment equipment: No standard drilling quote includes water treatment. You will not know what treatment is needed until after the water quality test. Budget $500 to $5,000 separately for any treatment equipment. See the well water treatment options guide for what systems cost.
Pressure tank in the house: Some quotes include a pressure tank outside or at the wellhead but not installation inside the house where it should be in cold climates.
Water quality testing: Initial water testing is sometimes included, often is not. The FHA minimum test for a loan transaction is separate from a comprehensive lab panel. Budget $150 to $400.
Site restoration: After a drilling rig operates on your property for several days, there will be soil disturbance, ruts, and debris. Ask whether site cleanup and grading is included or an extra charge.
Dry hole risk: What happens if the driller does not find water at adequate yield? Most contractors drill to a certain depth included in the quote and charge per foot beyond that. A dry hole clause in the contract defines your financial exposure if no water is found. Read this carefully.
What Drives Cost Up
These factors increase your project cost and should be discussed with your contractor before work begins.
Greater depth than expected. The single most common source of cost overruns in well drilling. If the driller reaches the contracted depth without finding adequate water and must continue, you pay the overage. Ask the contractor what depth they expect to reach water based on local well logs and what the per-foot rate is for overages.
Hard rock formations. If the driller encounters granite or dense basalt at any point in the borehole, the per-foot rate typically increases. This is often not mentioned in initial quotes and the language about rate changes can be buried in the contract.
Difficult site access. A drilling rig is a large truck. If reaching the drill site requires cutting through trees, building a temporary road, crossing soft ground, or maneuvering in tight spaces, expect a mobilization surcharge of $500 to $2,000.
Larger casing diameter. Standard residential wells use 4 to 6-inch casing. If you need higher flow rates for irrigation, livestock, or a large household, a 6 to 8-inch casing increases both material cost ($10 to $25 more per foot) and drilling time.
Steel casing requirement. If bedrock conditions require steel rather than PVC casing, the material cost per foot jumps from $6 to $11 per foot to $30 to $130 per foot. In some New England bedrock conditions, significant lengths of steel casing are standard.
Multiple pump installations during drilling. In some areas, drillers install a test pump at the end of drilling to confirm yield before installing the permanent submersible pump. This adds labor cost.
What Drives Cost Down
Soft, shallow geology. In areas with shallow water tables and soft soil — much of the Southeast and parts of the Midwest — well drilling is significantly faster and cheaper per foot.
Off-peak scheduling. Late fall and winter are slower periods for most well drillers in northern states. Some contractors offer 10 to 15 percent better pricing during their slow season. In areas where summer drought increases demand, spring and fall may be cheaper than July and August.
Bundling with neighboring properties. If your property is in a rural subdivision and multiple neighbors are drilling wells at the same time, some contractors offer volume pricing when a rig is already mobilized in an area. This is uncommon but worth exploring if the timing works.
Existing access and cleared land. A well site that is clear, flat, and accessible from the road with no obstacles reduces mobilization and setup time.
Red Flags in Contractor Quotes
No license or bond stated. Well drilling requires a state license in most states. Ask for the contractor's license number and verify it with your state's contractor licensing board before signing. Unlicensed drillers may not meet setback requirements for septic systems, and their work may not be accepted for FHA or VA loans.
Verbal quote with no written contract. Every well drilling project needs a written contract specifying the depth included in the base price, the per-foot rate for overages, what is and is not included, the warranty on materials and workmanship, and what happens in a dry hole scenario.
Quote that does not specify what happens if adequate water is not found. This is the most important clause in any well drilling contract. Read it before signing.
Quote significantly lower than every other bid. The lowest bid sometimes reflects a less experienced crew, inferior materials, or a driller planning to make up the difference through overage charges. Ask what grade of casing is being used and whether the pump is a name brand (Grundfos, Franklin, Goulds) or a generic import.
No mention of permit. A permit is required in virtually every US state for residential well drilling. A contractor who does not mention the permit is either pricing the job without it or planning to skip it. Either situation creates legal and financial problems at resale.
Deepening or Rehabilitating an Existing Well
Not all well projects are new installations. These are the alternatives when an existing well underperforms.
Deepening an existing well
Extends the borehole below its current depth to reach a lower water-bearing zone or a more productive portion of the aquifer. Cost: $3,000 to $10,000 depending on how much additional depth is needed. Not guaranteed to improve yield. The driller assesses whether the existing casing condition and diameter make deepening viable before committing.
Hydrofracturing (hydrofracking)
A technique used in bedrock wells where water is pumped into the well under high pressure to open fractures in the rock, increasing the flow rate into the well. Effective for wells with low yield due to limited fractures in the bedrock rather than low aquifer levels. Cost: $1,500 to $3,000. Success rate is reportedly 70 to 97 percent depending on source and geology. Much less expensive than deepening or drilling a new well. See the well running dry guide for when hydrofracturing is appropriate versus other solutions.
Well rehabilitation (cleaning and redevelopment)
Pumping, surging, and treatment of an existing well to restore yield lost to sediment accumulation, mineral deposits, or iron bacteria clogging. Cost: $500 to $2,500. Appropriate for older wells that have never been redeveloped. A 30-year-old well producing half its original yield is often a candidate for rehabilitation before considering deepening or replacement.
New well vs. deeper well: If an existing well is structurally compromised (failed casing, improper grout seal, contaminated by a persistent source), a new well at a different location is often preferable to rehabilitating or deepening the old one. Cost comparison: new well $8,000 to $20,000 versus deepening $3,000 to $10,000 with uncertain outcome. A licensed well contractor can assess which is more appropriate.
The All-In Cost: What You Are Actually Paying For Over 20 Years
The drilling cost is a one-time expense at the beginning of a system that should serve your household for 30 to 50 years. Framing the total cost over the system lifecycle puts the drilling investment in context.
| Cost Item | One-Time or Recurring | 20-Year Total Estimate |
|---|---|---|
| Well drilling and casing | One-time | $8,000 to $20,000 |
| Initial pump and pressure tank | One-time, replacement needed | $1,600 to $4,000 initial |
| Pump replacement (Year 10 to 15) | Once in 20 years | $1,000 to $2,500 |
| Pressure tank replacement (Year 10 to 15) | Once in 20 years | $600 to $1,500 |
| Annual water testing | Annual | $2,000 to $6,000 over 20 years |
| Treatment equipment (if needed) | Install once, maintain annually | $1,000 to $8,000 |
| Total 20-year cost | $14,200 to $42,000 |
For comparison, the average American household pays $600 to $900 per year for municipal water and sewer service — $12,000 to $18,000 over 20 years, at rates that have increased roughly 3 to 4 percent annually in most cities. Well ownership costs over 20 years are comparable or lower for most households, with the significant difference that the majority of the well cost front-loads in Year 1 while municipal costs are distributed monthly.
A properly functioning private well also adds $10,000 to $30,000 to property value in most rural and semi-rural markets, according to real estate professionals familiar with well-served properties.
How to Get Accurate Quotes
Get three quotes minimum, from licensed contractors only. Pricing varies enough that a single quote gives you no frame of reference. Three quotes let you identify outliers in either direction.
Ask every contractor these questions before they quote:
- What is your state contractor license number for well drilling?
- Can you pull well log data from neighboring properties to estimate depth?
- Is the quote turnkey (all-in for a working well) or drilling only?
- What is the per-foot rate for overages beyond the contracted depth?
- What casing material is specified and what grade?
- What pump brand and model is included?
- What happens if adequate water is not found at the contracted depth?
- Is the permit application included or extra?
- Is the water quality test included?
- Is electrical from the pump controls to my main panel included or extra?
- What is the warranty on labor and on the pump?
Ask to see the well logs from neighboring properties. Most states maintain databases of well completion reports. A contractor who has drilled extensively in your area can access these records and show you what depth and geology neighbors encountered. This is the best predictor of what your project will cost.
Request an itemized written quote. A written quote that separates drilling, casing, pump, pressure tank, electrical, permit, and testing costs lets you compare contractors on the same basis and identifies what each one is and is not including.
Frequently Asked Questions
How much does it cost to drill a well?
Drilling a residential water well costs $5,500 to $15,000 for a complete system at average depth (100 to 200 feet) in average geology. The drilling itself costs $25 to $65 per foot nationally, but the total project also includes casing ($6 to $11 per foot for PVC), a submersible pump ($800 to $1,800), pressure tank ($600 to $1,500), electrical hookup ($1,000 to $3,000), permit ($100 to $500), and initial water test ($150 to $400). Always request a turnkey all-in quote rather than a per-foot drilling rate, because those two numbers can differ by $5,000 to $10,000 on a typical project.
How deep does a residential well need to be?
Well depth is determined by where the water is on your specific property — you cannot choose it independently. Most residential wells in the United States are 100 to 300 feet deep. Areas with shallow water tables such as parts of the Southeast can reach water at 50 to 100 feet. Arid western states and New England bedrock areas regularly require 300 to 600 feet. Your contractor can access well log databases for your county to show what depth neighboring properties reached water, which is the best predictor of what your well will require.
What is included in a well drilling quote?
A well drilling quote can mean very different things from different contractors. A drilling-only quote covers the borehole, casing, and grout seal — typically $25 to $65 per foot. A complete or turnkey quote should also include the pump, pressure tank, electrical hookup to the well controls, permit, and water quality test. Always ask what specifically is and is not included. The difference between a drilling-only quote and a turnkey quote for the same well can be $5,000 to $10,000.
How long does it take to drill a well?
Drilling itself typically takes 1 to 3 days depending on depth and geology. The complete project including permit approval, drilling, pump installation, electrical hookup, and water testing runs 1 to 2 weeks from start to finish under normal circumstances. Permits can add time in jurisdictions with slower processing. Rocky geology slows daily footage and can extend the drilling phase.
Can I drill my own well?
Some states allow property owners to drill wells on their own land, but all states require permits, and most require the well to be drilled by a licensed contractor. Even in states that technically allow owner-drilling, the specialized equipment required makes true DIY impractical. The only genuinely DIY option is a driven point well (sand point) in sandy soil with a very shallow water table, using a kit that costs $300 to $500 — appropriate only for irrigation or non-potable uses, not for drinking water. For a residential drinking water well, use a licensed contractor.
How much does it cost to drill a well in hard rock vs. soft soil?
Hard rock formations (granite, gneiss, basalt) cost $45 to $85 per foot to drill because they require specialized air rotary rigs, wear through expensive drill bits quickly, and progress slowly — sometimes only 20 to 30 feet per day versus 100 feet per day in soft soil. Soft formations (sand, gravel, unconsolidated sediment) cost $15 to $35 per foot. A 200-foot well in soft soil at $25 per foot costs $5,000 in drilling. The same 200-foot well in granite at $65 per foot costs $13,000. Your local contractor can tell you what geology to expect based on neighboring well logs.
How much does it cost to deepen an existing well?
Well deepening costs $3,000 to $10,000 depending on how much additional depth is needed and the geology. Deepening is not always possible — the existing casing diameter and condition must support it. An alternative for low-yield bedrock wells is hydrofracturing, which costs $1,500 to $3,000 and achieves success in 70 to 90 percent of cases by opening fractures in the rock to increase water flow into the well. See the well running dry guide for the full decision framework on when to deepen, hydrofracture, or drill a new well.
Does a well add value to a property?
A properly functioning private well typically adds $10,000 to $30,000 to property value in rural and semi-rural markets where wells are the normal water source. Properties with wells are common in these markets and buyers expect them. A well that is documented with recent water test results and a recent professional inspection in good condition is a selling point, not a liability.
Glossary
Turnkey Quote
A well drilling quote that includes everything required for a complete, working well system: drilling footage, casing, grout seal, pump, pressure tank, electrical connection, permit, and water quality test. Contrasted with a drilling-only or per-foot quote that covers only the borehole itself. When comparing quotes, always compare turnkey costs rather than per-foot drilling rates.
Air Rotary Drilling
The dominant method for drilling through hard rock formations. Compressed air is pumped down the drill string to the drill bit, where it lifts rock cuttings back to the surface. Air rotary equipment is more expensive to operate than mud rotary equipment, requires larger compressors, and wears through drill bits faster in hard granite and basalt formations.
Well Development
The process of flushing and surging a newly drilled well to remove fine sediment, drilling debris, and loose material from the aquifer immediately adjacent to the well screen. Proper well development maximizes the well's flow rate and prevents the pump from drawing fine material that would damage its impellers.
Grout Seal (Annular Seal)
Cement or bentonite clay pumped into the space between the outside of the well casing and the borehole wall. The grout seal prevents surface water and shallow contaminated groundwater from channeling down the outside of the casing to the aquifer. Missing or inadequate grouting is one of the most common causes of bacterial contamination in residential wells.
Dry Hole
A well that does not produce water in sufficient quantity to meet household needs, typically defined as less than 1 GPM. Dry holes occur when the driller reaches the contracted depth without finding an adequate water-bearing zone. Dry hole risk varies significantly by region and local geology.
Hydrofracturing
A well rehabilitation technique in which high-pressure water is injected into an existing bedrock well to open and expand fractures in the rock, increasing the rate at which groundwater flows into the well. Costs $1,500 to $3,000 and is most appropriate for low-yield bedrock wells. Success rates range from 70 to 97 percent in appropriate geological conditions.
External Resource
The National Ground Water Association (NGWA) maintains the Find a Contractor tool at ngwa.org, which lists licensed well contractors by state along with their licensing credentials. The NGWA also publishes annual statistics on well drilling costs, depths, and yields by state, which are the most comprehensive industry-sourced data available for residential well cost estimation.
