Buying a water well involves a per-foot drilling price along with several fixed and run‑of‑the‑project costs. The cost per foot varies by depth, rock type, and total well scope, with the biggest drivers being drilling difficulty, casing, and site preparation. This article explains the typical cost per foot, what drives the price, and practical ways to budget.
| Item | Low | Average | High | Notes |
|---|---|---|---|---|
| Well Drilling (per foot) | $8 | $15 | $40 | Soft soil vs hard rock differences |
| Casing (per foot or per well) | $2 | $6 | $15 | PVC or steel, standard 6” common |
| Pump and Equipment | $1,200 | $2,200 | $4,800 | Includes submersible/jet pump setup |
| Permits and Fees | $100 | $1,000 | $2,500 | Local/state requirements vary |
| Site Prep/Access | $300 | $1,000 | $3,000 | Driveway/line clearance, grading |
| Delivery/Disposal | $50 | $150 | $600 | Drill cuttings and equipment moves |
Typical Cost Per Foot for Well Drilling by Depth and Rock Type
Prices vary widely by depth and geology, with per-foot fees following a practical range that reflects difficulty. In soft soil, drilling can run about $8-$15 per foot, while mixed soil toward sandstone climbs to $15-$30 per foot. Hard rock scenarios may reach $25-$50 per foot, depending on access and local market conditions. These per-foot figures are complemented by fixed costs for casing, pump equipment, permits, and site prep.
Major Price Components in a Well Drilling Quote
A clear breakdown helps compare quotes and avoid hidden add-ons. The typical quote splits into drilling, casing, pump equipment, and permitting. The table below shows a representative 1-well breakdown for a 150-200 ft bore in mixed soil.
| Cost Component | Low | Average | High | Notes |
|---|---|---|---|---|
| Drilling (feet x rate) | $1,200 | $2,500 | $6,500 | Depth and rock quality drive the total |
| Casing and Seals | $600 | $1,600 | $3,000 | Includes grout sealant in some regions |
| Pump and Controls | $1,200 | $2,000 | $3,800 | Dependent on pump type |
| Permits/Inspections | $100 | $900 | $2,000 | Varies by jurisdiction |
| Site Access/Prep | $200 | $800 | $2,200 | Grading, trenching readiness |
| Delivery/Disposal | $50 | $150 | $600 | Cuttings and equipment movement |
Key drivers that alter the final per-foot price
Depth and rock type are the top two price levers for well drilling. Deep wells add hundreds to thousands in labor hours, while rock hardening can push per-foot costs higher. Additionally, total bore length, access constraints, and the chosen pump system shift overall budgeting. For example, moving from 100 ft to 250 ft can raise drilling costs by a wide margin if rock is encountered below 150 ft.
Region and market differences that affect the per-foot rate
Where a well is drilled matters as much as how deep it goes. Coastal regions with higher labor rates and stricter permitting can see higher averages, while rural markets with ample drill crews may price more competitively. Midwest and Plains areas often land mid-range figures, whereas the Mountain West faces tougher access and longer travel times that lift totals.
Labor hours, crew size, and installation time
Labor is a major portion of the total cost. Typical residential well drilling crews range from two to four people, with hours scaling with depth and weather. For a 150- to 200-foot bore, plan 8-12 hours of on-site work, plus mobilization and startup. Per-hour rates commonly fall in the $75-$125 range, depending on region and crew experience.
Additional items that commonly appear on the quote
Some quotes add-on essential components that affect total price. Examples include manual well disinfecting, electrical wiring for the pump, pressure tank installation, and initial water testing. Expect a few hundred dollars for testing and startup, and several hundred more if remote power or trenching is required.
Permits, inspections, and local regulatory costs
Permits can significantly influence the budget in certain counties or states. Permit fees may be a flat charge or based on depth, with inspection fees added after completion. Some jurisdictions require well water testing before the system is deemed ready, adding to the initial outlay but protecting long-term reliability.
Budgeting scenarios: domestic wells vs small agricultural setups
Project scope drives per-foot pricing as much as depth. A typical single domestic well at 120-180 ft in soft soil might cost in the $12,000 to $25,000 range, including casing, pump, and permits. For a larger agricultural well with deeper reach and higher flow requirements, the overall price may range from $25,000 to $70,000 or more, with per-foot drilling in the $20-$40 band depending on rock and access.
| Scenario | Depth Range | Per-Foot Range | Estimated Total | Notes |
|---|---|---|---|---|
| Residential Well | 100-180 ft | $12-$28 | $12,000-$25,000 | Standard casing and pump |
| Agricultural Well | 200-400 ft | $20-$40 | $25,000-$70,000 | Higher flow, longer range |
| Hard Rock Site | 150-300 ft | $25-$55 | $20,000-$60,000 | Rock faced challenges |
