The cost to build a well in the United States is usually $5,000-$15,000 for a new residential drilled well, with an average near $9,000. Depth, local geology, casing, pump equipment, permits, and the distance from the well to the house can move a quote well above or below that range.
| Item | Low | Average | High | Notes |
|---|---|---|---|---|
| Residential drilled well | $5,000 | $9,000 | $15,000+ | Typical complete installation; difficult sites can cost more |
| Drilling and casing | $25 per ft | $45 per ft | $65+ per ft | Rates vary with depth, geology, and casing needs |
| Well pump and controls | $1,000 | $2,000 | $4,000+ | Depends on pump type, depth, and capacity |
| Water testing and treatment | $100 | $500 | $2,500+ | Basic testing costs less than treatment equipment |
What a residential drilled well costs by depth
A standard residential drilled well commonly costs $5,000-$15,000, including drilling, casing, a basic submersible pump, and connection near the home. A 100- to 200-foot well on an accessible site may fall near the middle of that range; a deeper well or one requiring specialized casing can exceed $20,000.
Drilling is often quoted at roughly $25-$65 or more per foot, but that rate may not include the pump, pressure tank, trenching, water testing, or plumbing hookup. Ask whether the quote covers a completed, operating system or only the borehole. Assumptions: typical U.S. residential site, standard materials, ordinary access, and no major water-treatment equipment.
For budget planning, $9,000 is a reasonable starting estimate for a straightforward residential drilled well, not a guaranteed local price.
Which drilling, casing, and pump charges appear on quotes
Well bids can group work differently, so compare the included tasks rather than relying on one per-foot number. The ranges below are broad U.S. estimates; local contractor rates, materials, and site conditions affect totals.
| Quote component | Typical price | What can change it |
|---|---|---|
| Drilling | $15-$40 per ft | Rock, soil instability, depth, and rig access |
| Casing and well screen | $10-$25 per ft | Diameter, material, and ground conditions |
| Pump, wiring, and controls | $1,000-$4,000 | Depth, pump capacity, and electrical work |
| Pressure tank and fittings | $300-$1,200 | Tank size and system configuration |
| Trenching and house connection | $500-$3,000 | Distance, surface restoration, and obstacles |
| Testing and permits | $100-$1,000 | Local fees and required water tests |
A complete written quote should identify drilling, casing, pump equipment, electrical work, testing, and the house connection as separate inclusions or charges.
How depth, rock, and flow rate change the final price
Depth is a major cost driver: each additional 50 feet can add roughly $1,250-$3,250 at common drilling-and-casing rates, before equipment or hookup changes. A 300-foot well may therefore cost several thousand dollars more than a 150-foot well, especially when deeper installation requires a higher-capacity pump or more cable.
Geology also matters. Hard rock can slow drilling and increase wear, while loose or collapsing formations may require additional casing or a larger bore. A target yield of 5 gallons per minute may need less equipment than a high-demand system designed for 10 gallons per minute or more. The driller may not know the final depth or yield until work is underway.
Confirm the per-foot rate, casing allowances, and charges if the well exceeds the planned depth before signing.
Cut well costs by controlling the hookup and equipment scope
Compare at least three local bids using the same estimated depth, casing specification, pump capacity, and connection distance. A low drilling rate may exclude charges that another contractor includes, so request a line-item total and clarify how unexpected depth or failed yield is priced.
Keep the well site close to the house when practical, since long trenches and difficult surface restoration can add hundreds or thousands of dollars. Avoid buying a larger pump or treatment system without evidence that the household needs it; water testing can identify whether treatment is necessary and what type is appropriate.
Scope control and apples-to-apples bids usually save more than choosing equipment by sticker price alone.
How far regional well prices can vary
Rural areas with several active drillers may have lower travel and scheduling costs, while remote locations can carry mobilization charges. Local geology can outweigh broad regional averages: a shallow, productive aquifer may be less expensive than a deep rock well in the same state.
As a planning allowance, quotes in high-cost metro-adjacent markets may run about 10%-25% above comparable work in lower-cost rural markets. Remote sites may add another $500-$2,000 for rig travel or setup, though some contractors fold that expense into their drilling rate. These are comparison ranges, not fixed regional tariffs.
Use nearby completed projects and local well records to judge whether a regional quote is plausible.
How many days drilling and installation usually take
A typical residential well may take one to three days of on-site drilling, followed by another day or more for pump installation and connection. Weather, access, rock, required depth, and contractor scheduling can stretch the calendar time. Permit approval and water testing may add days or weeks before the system is ready for normal use.
Drilling labor is generally included in a per-foot bid, but separate electrical or plumbing work may be charged at about $75-$150 per hour. Ask whether the crew rate, equipment mobilization, and any minimum service charge are included in the written estimate.
Request an estimated on-site schedule as well as a price, particularly when coordinating excavation or house construction.
Which permits, tests, and add-ons can raise the bill
Well permits and inspections are handled locally, and fees commonly range from about $50-$500, with some jurisdictions requiring additional review or testing. A basic bacteria and nitrate test may cost around $100-$300; broader mineral or contaminant panels can bring testing to $300-$800 or more.
Water treatment is usually a separate decision after test results. A basic filtration or softening setup may cost $500-$2,500 installed, while specialized systems can exceed $3,000. Old-well abandonment, if needed, can add roughly $500-$2,000 depending on depth and local rules. Confirm whether the bid includes disposal, disinfection, and required inspection visits.
Check county or state requirements before drilling because missing permits can cause delays and added correction costs.
Three sample well quotes for different property conditions
These examples illustrate how depth and site scope shape an estimate; they are not contractor offers. Each assumes a private residential well and ordinary equipment, with local pricing still determining the actual bid.
| Scenario | Work and assumptions | Estimated total |
|---|---|---|
| Shallow, accessible site | 120 ft at about $40 per ft for drilling and casing; basic pump, testing, short hookup | $6,000-$8,000 |
| Typical drilled well | 200 ft at about $45 per ft; pump and tank, electrical connection, standard testing | $9,000-$13,000 |
| Deep, difficult formation | 350 ft at about $55-$65 per ft; added casing, stronger pump, longer hookup | $20,000-$30,000 |
The most useful comparison is the total installed price tied to a stated depth, yield target, and list of included work.
