Well Drilling Cost Guide 2026: How Much to Drill a Water Well

Average Well Drilling Costs (2026)

• Total well installation (drilling, casing, pump, system): $5,000–$20,000+ for typical residential well
• Drilling cost: $15–$40 per foot, depending on soil/rock conditions and region
• Average residential well depth: 100–300 feet (varies widely by location)
• Well casing (steel or PVC): $10–$30/linear foot
• Submersible pump: $500–$2,000 installed (deeper wells need higher-horsepower pumps)
• Pressure tank and controls: $300–$1,000
• Well permit: $100–$500 (required in most jurisdictions)

Factors That Drive Cost

• Depth to water table: Deeper wells cost proportionally more. Regional geology determines depth — some areas have water at 50 ft; others require 400+ ft.
• Rock drilling: Drilling through solid rock is significantly more expensive and time-consuming than drilling through soil or sediment
• Well yield: Most residential wells need 3–5 gallons per minute minimum flow rate
• Water quality: Some areas have naturally high iron, sulfur, or hardness — treatment systems add $500–$5,000

Well vs. Municipal Water

Well installation is a significant upfront investment but saves the ongoing cost of municipal water bills ($600–$1,200+/year for a typical household). For rural properties without municipal access, wells are the only option. In areas with municipal service, a well may be used for irrigation only to reduce water bills — requires separate water and irrigation meters.
