Water Well Drilling Cost Per Foot in Iowa (2026): $28-$58/ft

When Iowa 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 $58 per foot — is the single most important thing you can do before signing a contract. This guide breaks down per-foot drilling costs across Iowa so you can evaluate quotes with confidence.

What’s Included in Iowa Per-Foot Pricing

Most Iowa 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 Iowa (Iowa Department of Natural Resources (DNR); county well permits may be required locally) — typically $50–$500

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

Casing Cost Per Foot in Iowa

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 Iowa with hard bedrock or deeper wells (typically the upper end of the 40–500 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 Iowa

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

0–200 feet: The most straightforward drilling. Standard rigs handle these depths easily; formations are usually softer. Rates stay at the $28–$40 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 Iowa’s range ($58/ft) or beyond. Iowa’s deepest wells are typically in the 400–500+ ft range.

Many Iowa 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 Iowa

Iowa’s glacial drift covers most of the state with till, loess, and buried channel sands and gravels that provide productive shallow aquifers. Deeper wells tap the Jordan Sandstone and other Cambrian-Ordovician formations, which produce reliable but sometimes mineralized water.

The geology summarized above is the primary driver of per-foot cost variation within Iowa. Areas with softer sedimentary formations drill faster and cheaper. Areas with limestone, granite, or volcanic rock require slower, more expensive methods. Iowa’s primary aquifer — the Jordan Sandstone Aquifer / Glacial Drift Aquifers / Dakota Aquifer (western Iowa) — sits at 30-100 feet in alluvial and glacial deposits; 150-1,000 feet for deep bedrock aquifers, which directly affects how deep your well must go.

Total Well Cost Estimates in Iowa

Here’s what Iowa 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–$2,320	$3,620–$7,320
175 ft (typical)	$4,900–$10,150	$7,400–$15,150
500 ft (deeper)	$14,000–$29,000	$16,500–$34,000
500 ft (deepest typical)	$14,000–$29,000	$16,500–$34,000

How to Compare Per-Foot Quotes

When you receive quotes from multiple Iowa 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. Iowa requires water well contractors to be certified by Iowa DNR.

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

When to Drill in Iowa

April through November; spring flooding on Iowa’s rivers can delay access to bottomland sites

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 Iowa?

Iowa well drilling costs $28–$58 per foot in 2026, with $40 per foot as the average. Total cost depends on depth — a typical 175-foot well costs $4,900–$10,150 for drilling alone, plus $2,500–$5,000 for pump and connection.

Why is well drilling cost per foot different across Iowa?

Iowa’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 Iowa 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 Iowa?

In Iowa, residential well depths typically range from 40 to 500 feet, with 175 feet being the average. Your specific depth depends on local geology, target aquifer, and how productive nearby wells have been. The Jordan Sandstone Aquifer / Glacial Drift Aquifers / Dakota Aquifer (western Iowa) is Iowa’s primary residential aquifer, sitting at 30-100 feet in alluvial and glacial deposits; 150-1,000 feet for deep bedrock aquifers.

Is it cheaper to drill a shallow well in Iowa?

Yes — both the per-foot rate and total cost are lower for shallow wells. A 40-foot well costs $1,120–$2,320 for drilling, while a 500-foot well runs $14,000–$29,000. However, you can’t choose your well depth — it depends on where the productive aquifers are beneath your property.

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

Most Iowa 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 Iowa?

Get at least three quotes from licensed drillers, drill during the slower season (april through november 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.
