A deep well typically costs $8,000-$25,000 for a drilled, cased residential water well with a pump, though difficult sites or depths over 400 feet can push the total above $30,000. Deep well cost depends most on depth, rock conditions, casing requirements, pump capacity, and local drilling rates.
| Item | Low | Average | High | Notes |
|---|---|---|---|---|
| Drilling and casing | $5,000 | $12,000 | $25,000 | Roughly 150-400 feet; geology affects rates |
| Complete residential well | $8,000 | $16,000 | $35,000+ | Includes pump and basic connections |
| Drilling rate | $25/ft | $45/ft | $80+/ft | May not include casing or equipment |
What a 200-foot residential deep well usually costs
A complete 200-foot well commonly runs $10,000-$20,000, with an average near $15,000. That estimate assumes ordinary residential access, standard steel or PVC casing, a submersible pump, and no unusual water treatment or long utility trench. The drilled hole alone may cost $6,000-$13,000, depending on rock and casing needs.
Compare complete-system quotes, not just the advertised drilling rate. Some bids price each foot drilled but exclude casing, pump installation, pressure tank, testing, trenching, or permits. Assumptions: U.S. residential property, standard materials, normal equipment access, and no major treatment system.
How drilling, casing, pump and plumbing divide the quote
Line items help show whether a contractor has included the equipment and finish work needed to deliver usable water. Rates vary by market and well design; the ranges below are typical planning figures rather than fixed national prices.
| Cost item | Low | Average | High | Typical basis |
|---|---|---|---|---|
| Drilling | $25/ft | $45/ft | $80+/ft | Depth and geology |
| Casing and screen | $1,000 | $3,000 | $7,000 | Material, diameter, and length |
| Pump and pressure tank | $1,200 | $2,500 | $5,000 | Capacity and installation |
| Labor and setup | $800 | $1,800 | $4,000 | Rig mobilization and crew time |
| Permits and water testing | $150 | $600 | $1,500 | Local fees and test scope |
Labor may be bundled into the drilling or setup charge. When separately billed, a two- or three-person crew and rig can cost $100-$250 per crew-hour, depending on the area and equipment.
Ask whether casing, pump, pressure tank, testing, and connection to the house are included. A low per-foot price may leave thousands of dollars in add-ons.
Depth, rock hardness and casing diameter change the price
Every additional 50 feet can add about $1,250-$4,000 at common drilling rates, before any added casing or pump requirements. A site needing 350-500 feet of drilling can therefore cost substantially more than a 150-200-foot well, even with similar equipment.
Hard granite, fractured bedrock, unstable formations, or a dry first bore can raise drilling time and material use. Casing diameter also matters: a typical 5- or 6-inch residential well is generally less expensive to equip than a wider 8-inch design. Local rules, water-table depth, and the required yield may dictate those specifications.
Confirm the planned depth and the price for each additional foot before work begins. Some contractors also charge a separate rate for casing, difficult formations, or a second drilling attempt.
Can a shared well or smaller pump lower the bill?
Cost control starts with matching the design to the property’s actual water demand. A smaller household may need less pump capacity than a large home with irrigation, but undersizing can cause weak pressure or shorten equipment life. Ask a licensed well contractor to size the pump to the expected flow rate and total lift.
Where permitted, a shared well can spread drilling and equipment expenses among neighboring properties, but it requires a recorded agreement for access, maintenance, repairs, and electric costs. Avoid paying for unnecessary depth or upgrades; do not reduce required casing, sanitation protections, or code-compliant construction to lower the bid.
Set a written scope and change-order limit before drilling starts. Get approval rules for added depth, extra casing, or a failed bore so unexpected charges are documented.
Regional drilling rates vary with geology and contractor access
Quotes in remote areas may run 10%-25% above nearby-market estimates if a rig must travel farther or mobilize for a single job. High-demand regions and places with difficult permitting can also cost more. Conversely, several local drillers competing for work may keep standard installations closer to the lower end.
Rock conditions can matter more than state lines: hard-rock areas may have higher drilling charges, while sedimentary formations can require extensive casing or sealing. Request two or three itemized quotes from companies familiar with the local aquifer and county rules.
Use local bids for comparison rather than a national per-foot rate alone. A contractor’s experience with nearby wells can make its estimate more useful for predicting depth and yield.
How long does a 200-foot well take to drill?
A straightforward well may take one to three days of drilling, while setup, pump installation, testing, and site work can extend the project to several days or longer. Rock, weather, limited rig access, permitting, and waiting for equipment can delay the schedule. A crew may drill at different speeds depending on formation, so a promised daily footage rate is not a guaranteed completion date.
Ask whether the quote includes mobilization and return visits. Separate trips for pump installation or testing can add labor or travel charges, especially for rural properties.
What do pump, testing and site work add?
A submersible pump and pressure tank commonly add $1,200-$5,000, depending on pump depth, flow needs, and equipment quality. Water testing may cost $100-$400 for basic bacteria and mineral screening; broader contaminant panels can exceed $600. Water treatment is usually separate and may add $500-$5,000 or more, based on the issue and system type.
Trenching from the well to the house may add roughly $10-$30 per linear foot, excluding difficult rock or major restoration. A well cap, electrical connection, disinfection, and disposal of drilling spoils may be included or separately billed. Permits and inspections vary by county, commonly adding $150-$1,500.
Check the quote for electrical work, trench length, testing, disinfection, and cleanup. These items often explain why two bids with similar drilling rates have different totals.
Three deep-well quotes show how depth changes totals
A 150-foot well in accessible ground might be quoted at $35 per foot for drilling, or $5,250, plus $3,500 for casing, pump, tank, and testing, totaling about $8,750. This example assumes no treatment system or extended trench.
A 250-foot well at $45 per foot has $11,250 in drilling charges. Adding $5,500 for casing and equipment and $1,000 for permits, testing, and setup brings the estimate to about $17,750. A 400-foot rocky well at $70 per foot has $28,000 in drilling alone; casing, pump, and site work could lift the complete price to $35,000-$42,000.
Use these examples as scope comparisons, not guaranteed bids. Request the estimated depth, per-foot overage rate, included equipment, and total allowances in writing.
