Cost to Drill a Well in Colorado
Water wells in Colorado average about 245 feet deep across the 656,114 records in our database. At typical U.S. drilling rates, that puts the drilling and casing at roughly $6,300 to $9,400, before the pump, tank, treatment, and permits that complete a working system. Here is how the numbers break down, and the real Colorado data behind them.

Typical U.S. well drilling rates by depth
These are national average residential rates for the drilling and casing, not Colorado-specific prices. Rates fall into depth bands, with a setup (mobilization) fee on top. Use them as a yardstick, then get local quotes.
| Well depth | Drilling + casing (per ft) | Setup fee |
|---|---|---|
| Up to 100 ft | $28 - $42 | $400 - $600 |
| 101-300 ft | $24 - $36 | $400 - $600 |
| 301-600 ft | $25 - $30 | $750 - $800 |
| 601 ft and deeper | $21 | $1,000 |
National residential rate model, drilling and casing only. Higher per-foot rates apply to larger casing and hard-rock drilling. Pump, pressure tank, treatment, and permits are separate (see below).
What Colorado well records actually show
Cost follows depth, so the most useful Colorado number we have is the real one: our database holds 656,114 water-well records across Colorado, with completed wells averaging about 245 feet deep. The typical static water level - how far down the water table sits - runs about 118 feet across 337,332 recorded readings. These are real construction records you can review before you hire.

What that means for a typical Colorado well
Illustrative drilling + casing at 245 ft
$6,300 - $9,400
This applies the national residential rate ($24 to $36 per foot at this depth) to Colorado's real average well depth of 245 feet. It is an illustration built from a national rate card and Colorado's recorded average depth - not a quote, and not a price observed in Colorado. Your actual cost depends on your site's depth, geology, and casing, plus the pump, tank, treatment, and permits covered below.
One more thing quotes can't promise: depth. Nobody knows exactly how deep the water is until the drill finds it, so drillers quote a per-foot rate against an estimated depth - and if your well has to go deeper to reach a reliable aquifer, the extra footage bills at that same rate. That is normal practice, not a sign of a dishonest driller. Budget a 15-25% depth contingency above any estimate, and plan for the deeper half of your local range rather than the shallowest case.
Beyond the hole: the complete water system
The drilled hole and casing are only part of the bill. A working well also needs a pump and pressure tank, wiring and a pitless adapter, a sanitary cap and grouting, water testing, and often treatment for hardness, iron, or bacteria. Add it up and a complete private well system commonly runs $10,000-$50,000 for Colorado, based on our state cost research, versus $5,000-$15,000 nationwide. The low end is a shallow well with simple equipment; the high end is a deep well with treatment and difficult access. A typical Colorado project takes 2-4 months from planning to usable water.
What drives the cost of a well in Colorado
Depth
The biggest lever. Colorado wells average about 245 feet, but deeper aquifers mean more feet at the per-foot rate.
Geology and casing
Hard rock drills slower and can push per-foot rates toward the high end. Loose or caving formations need more casing, which adds material cost.
Water table and yield
The water table around Colorado sits near 118 feet in our records, but wells are drilled well past it to reach a dependable, year-round supply.
Pump, tank, and treatment
The pump, pressure tank, and any treatment for hardness, iron, or bacteria are a large share of a complete system - often several thousand dollars.
Permits and testing
Colorado: State permit required (CRS 37-90-137). Permit, inspection, and water-test fees are usually modest but affect the timeline.
Site access
A rig needs room to work. Tight lots, long driveways, steep grade, or remote sites raise mobilization and labor.

Cost figures on this page are national averages from DrillerDB's rate model paired with real Colorado well-depth records. They are estimates for planning, not quotes. Depth quotes are per-foot estimates, and actual drilling can run past the quoted depth, so budget 15 to 25 percent of leeway and ask your driller how overage is billed. Always confirm with a licensed local driller before you budget a project.
