Plan a residential well in Oregon
WDF planning range centered on the reviewed Oregon well-report average. Basalt, dry-hole risk, casing and site access can create a much wider quote spread than the average suggests.

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.

Local cost drivers
Why Oregon quotes vary by area
Cascade and central volcanic areas
Basalt and other volcanic formations can make penetration and water-bearing fractures unpredictable.
Higher rock and depth riskEastern Oregon
Long mobilization distances and variable basin aquifers can add both travel and depth costs.
Site-specificVerify the people doing the work
Use an Oregon-licensed and bonded well constructor. The state publishes a lookup for current constructors.
Open the licence lookup guide →Confirm the permit path
The constructor files the well report and must follow Oregon construction standards. A landowner who wants to construct a well personally needs the separate state permit and must meet its rules.

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.

Frequently asked questions
Oregon well-drilling questions
How much does it cost to drill a well in Oregon?
WDF’s 2026 planning range is $5,100–$17,300 USD. WDF planning range centered on the reviewed Oregon well-report average. Basalt, dry-hole risk, casing and site access can create a much wider quote spread than the average suggests.
How deep is a residential well in Oregon?
The reference point used here is about 203 ft in the reviewed record set. A nearby completion record is more useful than a broad average, and only drilling confirms the final depth and yield.
Do I need a licensed well driller or a permit in Oregon?
Use an Oregon-licensed and bonded well constructor. The state publishes a lookup for current constructors. The constructor files the well report and must follow Oregon construction standards. A landowner who wants to construct a well personally needs the separate state permit and must meet its rules.
What should a complete well quote include?
Compare drilling, casing, grout, pump, pressure tank, electrical work, permit or filing fees, yield testing, disinfection, laboratory testing, restoration, over-depth pricing and dry-hole terms on separate lines.

Where these facts come from
Depth, licensing and permit statements are checked against government records. Cost figures are WDF planning estimates derived from those records and the published 2026 cost model.
