Well Drilling Cost in Oregon: $28–$65/ft Price Guide (2026)

About 23% of Oregon households rely on private water wells — concentrated in rural areas surrounding the Willamette Valley, central Oregon around Bend, and coastal communities. Oregon’s diverse geology means drilling costs vary dramatically between regions. A shallow valley well costs a fraction of what a deep basalt well in the high desert runs. Here’s what to budget in 2026.

Oregon Well Drilling Costs at a Glance

Cost Factor	Range
Average total project cost	$8,400
Cost per foot	$28–$65
Average well depth	200 feet
Typical depth range	40–600 feet
Permit costs	$150–$400

Your total cost depends primarily on depth and geology. A 100-foot well in Willamette Valley alluvium costs far less than a 400-foot well through Cascades basalt.

Cost Per Foot by Region

Oregon spans three distinct geologic provinces, and drilling costs differ significantly in each.

Willamette Valley (Portland, Salem, Eugene, Corvallis)

Typical depth: 40–200 feet
Cost per foot: $28–$42
Geology: Alluvial sand and gravel deposits over Columbia River Basalt

The Willamette Valley has Oregon’s easiest and cheapest drilling conditions. Productive alluvial aquifers sit relatively close to the surface in much of the valley, and the soft sediment drills quickly. Expect $3,000–$8,000 for a complete residential well system. Properties on the valley fringes where bedrock is closer to the surface may cost more.

Cascades and Foothills (Bend, Redmond, Sisters, Sandy, Hood River)

Typical depth: 150–500 feet
Cost per foot: $35–$55
Geology: Volcanic basalt and andesite — hard rock drilling through fractured lava flows

Central Oregon around Bend is one of the fastest-growing regions in the state, and many new homes require wells. The Columbia River Basalt Group and Cascade volcanic rocks can be highly productive when the drill intersects fracture zones, but depths are unpredictable. Expect $8,000–$20,000 for a residential well. Some areas near Sisters and Black Butte Ranch require 400+ foot wells.

Coast Range and Oregon Coast (Lincoln City, Newport, Coos Bay, Astoria)

Typical depth: 80–300 feet
Cost per foot: $30–$50
Geology: Sedimentary sandstone and siltstone; some volcanic intrusions

Coastal Oregon has moderate drilling conditions. Sandstone formations are softer than basalt but harder than valley alluvium. Water yield can be variable — wells in steep coastal terrain sometimes have lower flow rates than valley wells. Budget $5,000–$12,000 for a typical coastal well. Access can be challenging on steep, wooded lots.

Eastern Oregon / High Desert (La Pine, Klamath Falls, Burns, Ontario)

Typical depth: 200–600 feet
Cost per foot: $35–$65
Geology: Basin and Range volcanic terrain with deep water tables

Eastern Oregon’s high desert has the deepest water tables in the state. The combination of deep drilling through hard volcanic rock makes this the most expensive region. Expect $12,000–$30,000+ for a residential well. Some ranch properties near Burns and Jordan Valley may need 500+ foot wells. Water quality issues (arsenic, fluoride, TDS) are more common here.

What’s Included in the Cost

A typical Oregon well drilling quote covers:

Drilling and casing — steel or PVC casing to prevent borehole collapse
Well screen — filters out sand and sediment at the water-bearing zone
Grout seal — cement seal to prevent surface contamination from entering the well
Development — flushing the well to clear drilling debris and maximize flow
Well cap — sanitary seal at the top of the casing
Start card and well report — required Oregon paperwork filed with OWRD

Not typically included (budget separately):

Additional Cost	Price Range
Submersible pump + installation	$1,000–$3,500
Pressure tank	$300–$1,500
Electrical hookup	$500–$1,500
Water line to house	$500–$3,000
Water testing	$150–$500
Water treatment system	$500–$5,000

With pump, pressure tank, and connections, a complete well system in Oregon typically runs $10,000–$18,000 for average depths.

Oregon Permits and Regulations

Oregon has some of the most thorough well construction regulations in the country. All wells are regulated by the Oregon Water Resources Department (OWRD).

Key requirements:

Start card required — the driller must file a start card with OWRD before drilling begins ($150–$400)
Licensed driller required — Oregon requires all well constructors to hold an OWRD license. Separate licenses exist for drilling, pump installation, and monitoring wells. No homeowner exemption — you cannot legally drill your own well
Well completion report — required within 30 days of completing the well; becomes part of Oregon’s public well log database
Domestic use exemption — exempt wells may use up to 15,000 gallons per day for domestic purposes without a separate water right permit. This covers virtually all residential wells
Setback distances — minimum 50 feet from septic tanks, 100 feet from drain fields, and varying distances from property lines depending on the county
Abandonment — unused wells must be properly decommissioned per OAR 690-220; estimated cost $800–$2,000

Oregon’s well log database is publicly searchable through the OWRD website — check it before getting quotes to see what depths and yields neighboring wells produce.

Water Quality Concerns

Oregon well water commonly contains:

Arsenic — naturally occurring in volcanic aquifers, particularly in central and eastern Oregon. Oregon’s action level is 10 ppb (same as EPA)
Radon — dissolved radon gas is common in granite and volcanic rock wells throughout the state
Iron and manganese — causes staining and metallic taste; treatable with filtration. Common in both valley alluvium and basalt wells
Nitrate — from agricultural runoff in the Willamette Valley and irrigated areas of eastern Oregon
Naturally elevated fluoride — in some eastern Oregon volcanic aquifers

Budget $150–$500 for a comprehensive water test after drilling. Oregon doesn’t require testing for private wells, but it’s strongly recommended. If treatment is needed, expect $500–$5,000 depending on the contaminants.

Best Time to Drill

Oregon’s wet climate affects drilling schedules, especially west of the Cascades:

April through November is the primary drilling season in western Oregon — summer and early fall offer the driest conditions and best site access
May through October in eastern Oregon, where cold winters and snow can limit access to rural sites
Winter drilling is possible in the valley and lowlands but rain-soaked sites can be impassable for heavy drilling rigs
Book 4–8 weeks ahead during the busy spring/summer season. Fall appointments are often easier to schedule

How to Save Money

Get at least 3 quotes — drilling prices vary 20–40% between companies. Get free estimates from licensed Oregon drillers.
Check the OWRD well log database — knowing your likely depth before getting quotes prevents sticker shock and helps you compare bids accurately
Ask about depth limits — some drillers offer a maximum depth/price guarantee. This protects you if the well needs to go deeper than expected
Bundle drilling + pump — hiring one company for the complete installation can save $500–$1,500 vs. separate contractors
Time it right — late fall can offer shorter wait times and occasionally better pricing as the busy season winds down
Consider shared wells — Oregon allows shared domestic wells serving up to 4 residences, which splits the drilling cost

Frequently Asked Questions

How deep are most residential wells in Oregon? The average is about 200 feet, but it varies widely by region. Willamette Valley wells may be 60–150 feet. Central Oregon wells around Bend often run 200–400 feet. Eastern Oregon high desert wells can exceed 500 feet.

Can I drill my own well in Oregon? No. Oregon requires all well construction to be performed by an OWRD-licensed driller. There is no homeowner exemption. This ensures wells meet Oregon’s construction standards and protects groundwater quality.

How long does it take to drill a well in Oregon? Most residential wells are completed in 1–3 days of drilling. The full project — pump installation, electrical, and plumbing — takes 1–3 weeks from start to finish, depending on driller schedules.

Do I need a water right for a domestic well in Oregon? No — domestic wells are exempt from water right permitting under Oregon law, as long as use stays within the 15,000 gallons-per-day limit. This covers all normal household uses including lawn and garden watering. Irrigation wells for larger acreage may need a separate water right.

Is well water safe to drink in Oregon? Yes, when properly tested. Oregon doesn’t require private well testing, but OWRD strongly recommends testing for bacteria, nitrate, and arsenic at minimum. Test annually for bacteria and every 3–5 years for a comprehensive panel. Most Oregon well water is naturally high quality.
