How Much Does It Cost to Drill a Well? (2026 Complete Guide)

The average cost to drill a residential water well in the United States is $7,500, with most homeowners paying between $3,000 and $15,000 for a complete well system. Your actual cost depends on three main factors: how deep the driller has to go, what type of rock or soil they’re drilling through, and where you live.

This guide breaks down every cost involved in drilling a well — from the per-foot drilling charge to the pump, pressure tank, and connections — so you know exactly what to budget.

Well Drilling Costs at a Glance

Cost Factor	Typical Range
National average (complete system)	$7,500
Most homeowners pay	$3,000–$15,000
Drilling cost per foot	$25–$65
Average well depth	150–300 feet
Pump + pressure tank	$1,500–$5,000
Permits	$0–$500

A “complete system” includes drilling, casing, the well pump, pressure tank, and basic connection to your house. Some quotes cover only drilling — always confirm what’s included before comparing prices.

Cost Per Foot: The Biggest Variable

Well drilling is priced primarily by the foot. The deeper your well, the more you pay. Per-foot rates vary by geology:

Geology	Cost Per Foot	Common Regions
Sand and gravel	$25–$35	Coastal plains, river valleys, upper Midwest
Clay and sediment	$25–$40	Gulf Coast, Great Plains
Sandstone	$30–$45	Appalachian region, parts of the West
Shale	$30–$50	Northeast, Midwest
Limestone	$35–$55	Southeast, Texas Hill Country, karst regions
Granite and hard rock	$45–$65+	New England, parts of the Southeast, mountain West

Why geology matters: Drilling through soft sand takes hours. Drilling through granite takes days and chews through expensive drill bits. The per-foot price reflects that difference.

What Per-Foot Pricing Covers

When a driller quotes “$35 per foot,” that typically includes:

Drilling the borehole — the actual drilling labor and equipment
Casing — steel or PVC pipe that lines the well and prevents collapse
Well screen — the filtered section at the bottom that lets water in
Grouting — cement seal around the casing to prevent surface contamination
Well development — flushing and surging the well to maximize water flow
Well cap — sanitary seal on top

What’s usually not included in per-foot pricing (and must be budgeted separately):

Additional Cost	Price Range
Submersible well pump	$800–$2,500
Pump installation labor	$200–$800
Pressure tank	$300–$1,500
Electrical hookup	$500–$1,500
Water line from well to house	$500–$3,000
Water quality testing	$100–$500
Permit fees	$50–$500

Total Cost by Well Depth

Here’s what most homeowners pay at common well depths, including pump and basic equipment:

Well Depth	Drilling Cost	Complete System Cost
50 feet	$1,250–$2,500	$3,000–$5,500
100 feet	$2,500–$5,000	$5,000–$8,000
150 feet	$3,750–$7,500	$6,000–$10,000
200 feet	$5,000–$10,000	$7,500–$13,000
300 feet	$7,500–$15,000	$10,000–$18,000
400 feet	$10,000–$20,000	$13,000–$23,000
500+ feet	$12,500–$30,000+	$16,000–$35,000+

The jump in cost at deeper depths comes from more casing material, longer pump wire runs, higher-capacity pumps, and more drilling time.

Cost by State

Drilling costs vary significantly by state because of differences in typical well depth, geology, labor rates, and permit requirements. Here are averages for the most-searched states:

State	Average Depth	Average Total Cost	Cost Per Foot
Texas	225 ft	$8,550	$25–$58
Arizona	350 ft	$12,500	$35–$60
Massachusetts	250 ft	$10,000	$35–$55
Florida	150 ft	$6,500	$25–$40
North Carolina	200 ft	$8,000	$30–$50
California	250 ft	$11,000	$35–$60
Virginia	200 ft	$8,500	$30–$55
Georgia	200 ft	$7,500	$28–$45
Michigan	150 ft	$7,000	$28–$42
Colorado	300 ft	$11,500	$35–$55

What Affects Your Well Drilling Cost

1. Depth to Water

This is the single biggest cost driver. If your neighbors’ wells are 100 feet deep, yours will likely be similar — but there are no guarantees. A driller may need to go 50 feet deeper than expected if the first water-bearing zone doesn’t produce adequate flow.

How to estimate depth: Ask your driller to check the well log database for your area. Most states maintain records of existing wells including depth, yield, and geology. Your neighbors’ wells are the best predictor.

2. Geology

Hard rock (granite, basalt, gneiss) costs $45–$65+ per foot to drill. Soft formations (sand, clay, sedimentary rock) cost $25–$40 per foot. Your driller knows the local geology and should quote accordingly.

3. Property Access

The drilling rig is a large truck that needs to reach your well site. If access requires clearing trees, building a temporary road, or maneuvering in tight spaces, expect additional charges of $500–$2,000. Steep terrain or remote locations add more.

4. Well Diameter

Standard residential wells use 4–6 inch casing. If you need higher flow rates (for irrigation, livestock, or a large household), a larger diameter (6–8 inch) casing increases drilling and material costs by $10–$25 per foot.

5. Your Location

Labor rates, equipment costs, and permitting fees vary by region. Wells in the Northeast and West Coast typically cost 15–30% more than wells in the Southeast and Midwest for similar depths and geology.

6. Pump and Equipment

A basic 1/2 HP submersible pump for a shallow well costs $800–$1,200. A 1–2 HP pump for a 300-foot well runs $1,500–$2,500. Add $300–$1,500 for a pressure tank and $500–$1,500 for electrical work.

Hidden Costs to Watch For

Some costs don’t show up in the initial drilling quote. Make sure you budget for:

Dry hole risk — If the driller doesn’t hit water at a reasonable depth, you may have to pay for the footage drilled and start over at a new location. Some drillers offer “water guarantees” — ask about this upfront.
Low-yield wells — If the well produces water but at a low rate (under 3 GPM), you may need a storage tank and booster pump system ($2,000–$5,000) to make it usable.
Water treatment — Well water often requires treatment. Iron filters, water softeners, UV sterilizers, or reverse osmosis systems cost $500–$5,000 depending on what’s in your water.
Electrical service — If your well site doesn’t have electrical service nearby, running power to the pump can cost $1,000–$3,000+.
Landscaping restoration — The drilling rig and support equipment will leave tracks and mud. Budget $200–$500 for site restoration.

Well Drilling Cost vs. Municipal Water

If you have access to both city water and well water, here’s how the costs compare:

Factor	Well Water	Municipal Water
Upfront cost	$3,000–$15,000	$1,000–$10,000 (tap/connection fee)
Monthly cost	$15–$50 (electricity only)	$30–$100+ (varies by usage and city)
Annual maintenance	$100–$300	$0 (utility handles it)
Lifespan	30–50+ years	Ongoing (as long as you pay)
Water quality	Your responsibility to test/treat	Utility tests and treats

Over 25 years, a well often costs less than municipal water, especially in areas with high water rates. But the upfront cost is higher and you’re responsible for maintenance. For a detailed comparison, see our guide on well water vs. city water.

The Well Drilling Process: What to Expect

Understanding the process helps you evaluate quotes and know what to expect on drilling day.

Before Drilling

Site selection — The driller selects a location based on distance from septic systems (usually 50+ feet required by code), property access, and geology
Permits — The driller or homeowner obtains required permits from the county or state
Utility locates — Call 811 to mark underground utilities before drilling begins

Drilling Day (1–3 Days)

Rig setup — The drilling truck positions over the well site
Drilling — The rig bores through soil and rock, advancing the hole. Most residential wells drill at 20–100 feet per day depending on geology
Casing installation — Steel or PVC casing is installed as the hole advances
Reaching water — The driller monitors for water-bearing formations and tests yield
Well screen — A screened section is installed at the aquifer depth
Grouting — Cement is pumped into the space between the casing and borehole to seal against contamination
Development — The well is flushed and surged to clear drilling debris and maximize flow

After Drilling (1–2 Weeks)

Pump installation — A submersible pump is lowered into the well on a pipe string
Pressure tank and controls — Installed in your basement, garage, or pump house
Electrical — The pump is wired to your electrical panel with a dedicated circuit
Water line — A buried pipe connects the wellhead to your house plumbing
Water testing — Samples are collected and sent to a lab for bacteria, nitrates, and other contaminants
Final inspection — The county or state inspector verifies the well meets code

How to Get the Best Price

Get at least 3 quotes — This is the most important step. Drilling prices can vary 20–40% between companies for the same well. Request free quotes from licensed contractors.
Ask what’s included — Some quotes cover drilling only. Others include pump, pressure tank, and connections. Compare apples to apples.
Check the well log database — Know your likely depth before getting quotes. This prevents being surprised by a deeper (and more expensive) well than expected.
Ask about dry hole policies — What happens if the driller doesn’t hit water? Some charge full per-foot rate regardless. Others offer a reduced rate for dry footage or will drill a second hole at reduced cost.
Don’t choose by price alone — The cheapest driller isn’t always the best value. Ask for references, verify licensing, and check reviews. A poorly constructed well can cost more in the long run.
Time it right — Late fall and winter are typically slower seasons. Some drillers offer off-season pricing or shorter wait times.

Frequently Asked Questions

How long does it take to drill a well? Actual drilling takes 1–3 days for most residential wells. The complete project — including pump installation, electrical, plumbing, and testing — usually takes 1–3 weeks from start to finish.

Can I drill my own well? In most states, homeowners can legally drill a well on their own property for domestic use. However, you need proper equipment (a drilling rig for anything over 50 feet) and must meet state construction standards. For most homeowners, hiring a licensed driller is more practical and ensures the well is properly built.

What if the driller doesn’t hit water? This is uncommon but possible, especially in hard rock areas. Most drillers have extensive local experience and check well log databases before drilling. If a dry hole occurs, discuss the driller’s policy — some will drill a second hole at reduced cost, others charge full rate for footage drilled. Clarify this before work begins.

How deep should a well be? Deep enough to reach a reliable aquifer with adequate flow for your needs (typically 5+ GPM for a household). There’s no universal “right” depth — it depends entirely on your local geology and water table. Your driller will base the depth on nearby well records and the formations they encounter while drilling.

Is well water safe? Well water is safe when properly tested and treated. Unlike municipal water, private well owners are responsible for testing. Test for bacteria and nitrates annually, and do a comprehensive panel (including heavy metals and volatile organics) every 3–5 years. Most well water is naturally high quality — many homeowners prefer it to chlorinated city water.

How long does a well last? A properly constructed drilled well lasts 30–50+ years. The pump typically needs replacement every 10–15 years ($1,000–$3,000). The well itself — the casing, screen, and grout seal — should last the life of the home with minimal maintenance.
