Well Drilling Cost FAQ
Answers to the most common questions about well drilling costs, process, and maintenance. Last verified April 2026.
How much does it cost to drill a well in 2026?
The average cost to drill a residential water well is $5,000 to $15,000, with most homeowners paying around $8,000 to $12,000 for a 150-foot well with pump and casing. Costs vary dramatically based on depth, geology, and location. Shallow wells in soft soil can cost as little as $1,500, while deep wells in hard rock may exceed $30,000.
How deep does a residential well need to be?
Residential well depth depends entirely on your local water table and geology. In areas with high water tables (like coastal Florida), wells may only need to be 50-100 feet deep. In arid western states or areas with deep bedrock aquifers, wells often need to be 200-400+ feet deep. Your local well driller or county health department can advise on typical depths in your area.
How long does it take to drill a well?
Drilling a residential water well typically takes 1 to 3 days for the actual drilling. However, the total project timeline including permits, scheduling, pump installation, and water testing usually spans 2 to 6 weeks. Complex geology or deep wells may take longer to drill.
Can I drill my own well to save money?
While it's physically possible to dig or drive a shallow well yourself (under 50 feet in soft soil), most states require a licensed well driller for drilled wells. DIY wells also carry risks: improper construction can contaminate your water supply and even your neighbors' wells. The permit, safety, and quality risks generally make professional drilling the better choice.
How much does a well pump cost to replace?
Replacing a well pump typically costs $1,500 to $5,000 including labor. Submersible pump replacement (the most common type) runs $1,800 to $4,500 because the pump must be pulled from deep in the well. Jet pumps are cheaper to replace at $800 to $2,000 since they're above ground.
Is well water safe to drink?
Well water can be perfectly safe to drink, but unlike municipal water, it is not regulated by the EPA. You are responsible for testing your well water regularly — at least annually for bacteria and nitrates. Many wells produce excellent water, but some may have naturally occurring contaminants (arsenic, radon, hardness minerals) that require treatment.
Does a well increase property value?
A well-maintained private well can increase property value by $5,000 to $20,000 in rural areas where municipal water isn't available. It's seen as essential infrastructure. However, in areas with available city water, the value increase is less significant since buyers have an alternative.
How often should well water be tested?
At minimum, test annually for coliform bacteria and nitrates. Test every 3-5 years for a broader panel including minerals, pH, and hardness. Test immediately if you notice changes in taste, color, or odor, or if there's been flooding, construction, or agricultural activity near your well.
What's the difference between well water and city water cost over time?
While a well costs $5,000-$30,000 upfront, it has no monthly water bill (just ~$30-50/month for pump electricity). City water costs $50-100/month. Over 20 years, well water typically costs $10,000-$42,000 total while city water costs $13,000-$29,000. The break-even point is typically 8-15 years.
Do I need a permit to drill a well?
Yes, in most US states. Over 45 states require a well drilling permit before any work begins. Permits typically cost $100-$500 and ensure your well meets setback distances from septic systems, property lines, and other wells. Your licensed well driller usually handles the permit application.
