Water Well Drilling Cost Per Foot in Oregon (2026): $28-$65/ft

When Oregon drillers quote you a price, it almost always comes down to a per-foot rate. Understanding what that rate includes — and why it ranges from $28 to $65 per foot — is the single most important thing you can do before signing a contract. This guide breaks down per-foot drilling costs across Oregon so you can evaluate quotes with confidence.

What’s Included in Oregon Per-Foot Pricing

Most Oregon drillers include the following in their quoted per-foot rate:

• Drilling labor and equipment mobilization — getting the rig to your property and the actual drilling operation
• Drill bit wear and fuel — consumables used during boring
• Basic borehole logging — recording depth, geology, and water-bearing zones
• Drilling fluid — mud rotary or air rotary medium for flushing cuttings

What’s Typically NOT Included

These items are typically quoted separately:

• Well casing — PVC or steel pipe lining the borehole ($8–$25 per foot)
• Well screen — slotted section at the water-bearing zone ($10–$20 per foot)
• Grout and seal — cement seal preventing surface contamination ($3–$8 per foot)
• Pump and pressure system — submersible pump, pressure tank, wiring ($2,500–$6,000)
• Electrical hookup — wiring from well to home electrical panel ($1,000–$3,000)
• Water testing — bacteria, mineral, and chemical analysis ($150–$500)
• Permit fees — varies in Oregon (Oregon Water Resources Department (OWRD); all wells require a start card before drilling and a well report after completion) — typically $50–$500

Always ask for an itemized quote to see exactly what your per-foot rate covers.

Casing Cost Per Foot in Oregon

Casing is one of the biggest cost variables beyond the drilling itself:

Casing Type	Cost Per Foot	Best For	Lifespan
Schedule 40 PVC (4”)	$8–$12	Shallow wells, sandy/sedimentary formations	30–50 years
Schedule 80 PVC (4”)	$10–$16	Standard residential, moderate depths	40–60 years
Steel (4”)	$15–$25	Deep wells, hard rock formations	50+ years
Steel (6”)	$20–$35	High-flow residential, light irrigation	50+ years

In areas of Oregon with hard bedrock or deeper wells (typically the upper end of the 40–600 ft range), steel casing is often required because PVC can crack at depth. In sandy/sedimentary regions and shallower wells, PVC handles the load.

How Depth Affects Per-Foot Rates in Oregon

Per-foot rates often increase with depth — even within Oregon:

0–200 feet: The most straightforward drilling. Standard rigs handle these depths easily; formations are usually softer. Rates stay at the $28–$42 range.

200–400 feet: Rates typically increase $5–$10 per foot above the base rate. Harder formations may be encountered, drilling takes longer per foot, more casing is required.

400–600 feet: Specialized equipment may be needed. Drill bit changes are more frequent and the risk of problematic formations increases. Add $10–$20 per foot above base rate.

600+ feet: Heavy-duty rigs, steel casing, and significantly more time. Rates can reach the upper end of Oregon’s range ($65/ft) or beyond. Oregon’s deepest wells are typically in the 500–600+ ft range.

Many Oregon drillers quote a base per-foot rate for the first 200–300 feet, then a higher rate for additional depth. Make sure your quote specifies the rate structure for different depth tiers.

Why Per-Foot Costs Vary in Oregon

Oregon’s Cascade Range has volcanic basalt and andesite with highly productive but deep aquifers in fractured lava flows. The Willamette Valley has alluvial deposits over Columbia River Basalt, while eastern Oregon’s high desert features Basin and Range geology with deep water tables.

The geology summarized above is the primary driver of per-foot cost variation within Oregon. Areas with softer sedimentary formations drill faster and cheaper. Areas with limestone, granite, or volcanic rock require slower, more expensive methods. Oregon’s primary aquifer — the Columbia River Basalt Group Aquifer / Willamette Valley Alluvial Aquifers / Basin and Range Volcanic Aquifers — sits at 20-80 feet in the Willamette Valley; 100-400 feet in the Cascades basalt; 200-600 feet in eastern Oregon basins, which directly affects how deep your well must go.

Total Well Cost Estimates in Oregon

Here’s what Oregon property owners actually pay when you combine per-foot drilling, casing, pump, and all other costs:

Well Depth	Drilling Only	Complete System (with pump, casing, electrical)
40 ft (shallow)	$1,120–$2,600	$3,620–$7,600
200 ft (typical)	$5,600–$13,000	$8,100–$18,000
500 ft (deeper)	$14,000–$32,500	$16,500–$37,500
600 ft (deepest typical)	$16,800–$39,000	$19,300–$44,000

How to Compare Per-Foot Quotes

When you receive quotes from multiple Oregon drillers:

1. Confirm what’s included. A $40/ft quote that includes casing is cheaper than a $30/ft quote where casing is extra.
2. Ask about depth tiers. Will the rate increase after 200 or 300 feet?
3. Get a not-to-exceed estimate. Good drillers cap the total cost based on expected depth in your area.
4. Check for mobilization fees. Some drillers charge $500–$2,000 to move the rig, especially for rural locations.
5. Verify licensing. Oregon requires all water well constructors to be licensed by OWRD.

We recommend getting at least three quotes. Request free quotes from licensed Oregon drillers to compare pricing in your area.

When to Drill in Oregon

April through November west of the Cascades; May through October in eastern Oregon; heavy rains limit winter access in western Oregon

Driller schedules typically fill 4–8 weeks in advance, especially in peak drilling season. Off-season drilling (where weather allows) sometimes captures 5–15% labor savings.

Frequently Asked Questions

How much does it cost to drill a water well per foot in Oregon?

Oregon well drilling costs $28–$65 per foot in 2026, with $42 per foot as the average. Total cost depends on depth — a typical 200-foot well costs $5,600–$13,000 for drilling alone, plus $2,500–$5,000 for pump and connection.

Why is well drilling cost per foot different across Oregon?

Oregon’s geology varies regionally — softer sedimentary formations drill faster and cheaper than hard limestone, granite, or volcanic bedrock. Wells targeting deeper aquifers also cost more per foot because of additional drill bit wear, slower progress, and the need for steel rather than PVC casing.

Does the per-foot rate include the well casing?

Usually not. Most Oregon drillers quote drilling and casing separately. PVC casing adds $8–$16 per foot; steel casing adds $15–$35 per foot. Always ask for an itemized breakdown so you know exactly what the per-foot rate covers.

How deep do you have to drill for water in Oregon?

In Oregon, residential well depths typically range from 40 to 600 feet, with 200 feet being the average. Your specific depth depends on local geology, target aquifer, and how productive nearby wells have been. The Columbia River Basalt Group Aquifer / Willamette Valley Alluvial Aquifers / Basin and Range Volcanic Aquifers is Oregon’s primary residential aquifer, sitting at 20-80 feet in the Willamette Valley; 100-400 feet in the Cascades basalt; 200-600 feet in eastern Oregon basins.

Is it cheaper to drill a shallow well in Oregon?

Yes — both the per-foot rate and total cost are lower for shallow wells. A 40-foot well costs $1,120–$2,600 for drilling, while a 600-foot well runs $16,800–$39,000. However, you can’t choose your well depth — it depends on where the productive aquifers are beneath your property.

Do Oregon well drillers charge a flat rate or per-foot rate?

Most Oregon residential well drillers quote per-foot rates, though some offer flat-rate packages where well depth is predictable. Per-foot pricing is more common because depth can vary even between neighboring properties. Some drillers quote a base rate for the first 200–300 feet and a higher rate for additional depth.

How can I get the best per-foot rate on well drilling in Oregon?

Get at least three quotes from licensed drillers, drill during the slower season (april through november west of the cascades is peak; outside that window can save 5–15%), and choose a property access point that minimizes mobilization costs.
