Water Well Drilling Cost Per Foot in Arizona (2026): $30-$70/ft

When Arizona 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 $30 to $70 per foot — is the single most important thing you can do before signing a contract. This guide breaks down per-foot drilling costs across Arizona so you can evaluate quotes with confidence.

What’s Included in Arizona Per-Foot Pricing

Most Arizona 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 Arizona (Arizona Department of Water Resources (ADWR); wells in Active Management Areas require a drilling permit and well registration) — typically $50–$500

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

Casing Cost Per Foot in Arizona

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 Arizona with hard bedrock or deeper wells (typically the upper end of the 100–1000 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 Arizona

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

0–200 feet: The most straightforward drilling. Standard rigs handle these depths easily; formations are usually softer. Rates stay at the $30–$45 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 Arizona’s range ($70/ft) or beyond. Arizona’s deepest wells are typically in the 900–1000+ ft range.

Many Arizona 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 Arizona

Arizona’s Basin and Range geology consists of deep alluvial basins filled with sand, gravel, and clay between mountain ranges of igneous and metamorphic rock. The Colorado Plateau in the north features layered sandstone and limestone formations with deeper water tables.

The geology summarized above is the primary driver of per-foot cost variation within Arizona. Areas with softer sedimentary formations drill faster and cheaper. Areas with limestone, granite, or volcanic rock require slower, more expensive methods. Arizona’s primary aquifer — the Central Arizona Basin / Basin and Range Alluvial Aquifers — sits at 100-600 feet in the Phoenix and Tucson basins; can exceed 1,000 feet in some desert areas, which directly affects how deep your well must go.

Total Well Cost Estimates in Arizona

Here’s what Arizona 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)
100 ft (shallow)	$3,000–$7,000	$5,500–$12,000
342 ft (typical)	$10,260–$23,940	$12,760–$28,940
500 ft (deeper)	$15,000–$35,000	$17,500–$40,000
1000 ft (deepest typical)	$30,000–$70,000	$32,500–$75,000

How to Compare Per-Foot Quotes

When you receive quotes from multiple Arizona 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. All well drillers must hold an Arizona Registrar of Contractors license.

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

When to Drill in Arizona

October through April; summer monsoon season brings flash flood risks and extreme heat slows drilling operations

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 Arizona?

Arizona well drilling costs $30–$70 per foot in 2026, with $45 per foot as the average. Total cost depends on depth — a typical 342-foot well costs $10,260–$23,940 for drilling alone, plus $2,500–$5,000 for pump and connection.

Why is well drilling cost per foot different across Arizona?

Arizona’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 Arizona 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 Arizona?

In Arizona, residential well depths typically range from 100 to 1000 feet, with 342 feet being the average. Your specific depth depends on local geology, target aquifer, and how productive nearby wells have been. The Central Arizona Basin / Basin and Range Alluvial Aquifers is Arizona’s primary residential aquifer, sitting at 100-600 feet in the Phoenix and Tucson basins; can exceed 1,000 feet in some desert areas.

Is it cheaper to drill a shallow well in Arizona?

Yes — both the per-foot rate and total cost are lower for shallow wells. A 100-foot well costs $3,000–$7,000 for drilling, while a 1000-foot well runs $30,000–$70,000. However, you can’t choose your well depth — it depends on where the productive aquifers are beneath your property.

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

Most Arizona 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 Arizona?

Get at least three quotes from licensed drillers, drill during the slower season (october through april is peak; outside that window can save 5–15%), and choose a property access point that minimizes mobilization costs. Request free quotes here to compare rates from drillers in your area.
