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

When Colorado 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 Colorado so you can evaluate quotes with confidence.

What’s Included in Colorado Per-Foot Pricing

Most Colorado 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 Colorado (Colorado Division of Water Resources (State Engineer’s Office); every well requires a permit before drilling) — typically $50–$500

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

Casing Cost Per Foot in Colorado

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 Colorado with hard bedrock or deeper wells (typically the upper end of the 50–700 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 Colorado

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

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 Colorado’s range ($65/ft) or beyond. Colorado’s deepest wells are typically in the 600–700+ ft range.

Many Colorado 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 Colorado

Colorado’s Front Range sits atop the Denver Basin aquifer system with interbedded sandstone and shale layers. The Eastern Plains overlie the Ogallala Formation’s sand and gravel, while the Western Slope taps fractured crystalline rock and sedimentary formations.

The geology summarized above is the primary driver of per-foot cost variation within Colorado. Areas with softer sedimentary formations drill faster and cheaper. Areas with limestone, granite, or volcanic rock require slower, more expensive methods. Colorado’s primary aquifer — the Denver Basin Aquifer System / Ogallala (High Plains) Aquifer — sits at 50-400 feet along the Front Range; 100-500 feet on the Eastern Plains; highly variable in mountain regions, which directly affects how deep your well must go.

Total Well Cost Estimates in Colorado

Here’s what Colorado 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)
50 ft (shallow)	$1,400–$3,250	$3,900–$8,250
250 ft (typical)	$7,000–$16,250	$9,500–$21,250
500 ft (deeper)	$14,000–$32,500	$16,500–$37,500
700 ft (deepest typical)	$19,600–$45,500	$22,100–$50,500

How to Compare Per-Foot Quotes

When you receive quotes from multiple Colorado 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. Colorado requires all water well contractors to be licensed by the State Board of Examiners of Water Well Construction and Pump Installation Contractors.

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

When to Drill in Colorado

April through October in most areas; mountain locations limited to June through September

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 Colorado?

Colorado well drilling costs $28–$65 per foot in 2026, with $42 per foot as the average. Total cost depends on depth — a typical 250-foot well costs $7,000–$16,250 for drilling alone, plus $2,500–$5,000 for pump and connection.

Why is well drilling cost per foot different across Colorado?

Colorado’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 Colorado 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 Colorado?

In Colorado, residential well depths typically range from 50 to 700 feet, with 250 feet being the average. Your specific depth depends on local geology, target aquifer, and how productive nearby wells have been. The Denver Basin Aquifer System / Ogallala (High Plains) Aquifer is Colorado’s primary residential aquifer, sitting at 50-400 feet along the Front Range; 100-500 feet on the Eastern Plains; highly variable in mountain regions.

Is it cheaper to drill a shallow well in Colorado?

Yes — both the per-foot rate and total cost are lower for shallow wells. A 50-foot well costs $1,400–$3,250 for drilling, while a 700-foot well runs $19,600–$45,500. However, you can’t choose your well depth — it depends on where the productive aquifers are beneath your property.

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

Most Colorado 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 Colorado?

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