Plan a residential well in California
WDF planning range for a complete residential system near the statewide domestic-well record average. County rules, casing, access and hard rock can move a quote outside it.

How the estimate works
Depth is only the first number
The range is calculated from government well records or depth guidance and the ground conditions commonly encountered in the area. It is not a published government price and it cannot predict whether a specific bore will be dry, unusually deep or difficult to reach.
Ask every bidder for one complete-system total. It should identify drilling, casing, grouting, pump, pressure tank, electrical work, permit or filing charges, water testing and restoration separately.

Why California quotes vary by area
Coastal basins
Layered sediments and local groundwater rules make county records especially important.
Site-specificSierra foothills and mountain areas
Granite and fractured rock can slow drilling and increase the per-foot rate.
Higher hard-rock riskVerify the people doing the work
Hire a California contractor with the CSLB C-57 Well Drilling classification and confirm that the licence is active for the company named on the quote.
Open the licence lookup guide →Confirm the permit path
Well permits and setback reviews are commonly handled locally. The driller should confirm the county environmental-health process and file the required well-completion report.
Review permit guidance →Quote checklist
Compare the same scope—not just the headline price
- Licence and insurance: match the name on the proposal to the current public record.
- Depth and per-foot terms: record the included depth, overage rate and dry-hole terms.
- Complete system: separate drilling, casing, grout, pump, tank, wiring, permit, test and restoration.
- Water and workmanship: ask about yield testing, disinfection, laboratory testing and written warranties.
