Alaska well drilling cost

Cost to Drill a Well in Alaska

Water wells in Alaska average about 138 feet deep across the 40,601 records in our database. At typical U.S. drilling rates, that puts the drilling and casing at roughly $3,700 to $5,600, before the pump, tank, treatment, and permits that complete a working system. Here is how the numbers break down, and the real Alaska data behind them.

Typical U.S. well drilling rates by depth

These are national average residential rates for the drilling and casing, not Alaska-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 Alaska well records actually show

Cost follows depth, so the most useful Alaska number we have is the real one: our database holds 40,601 water-well records across Alaska, with completed wells averaging about 138 feet deep. The typical static water level - how far down the water table sits - runs about 62 feet across 20,444 recorded readings. These are real construction records you can review before you hire.

What that means for a typical Alaska well

Illustrative drilling + casing at 138 ft

$3,700 - $5,600

This applies the national residential rate ($24 to $36 per foot at this depth) to Alaska's real average well depth of 138 feet. It is an illustration built from a national rate card and Alaska's recorded average depth - not a quote, and not a price observed in Alaska. 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 $12,000-$50,000+ for Alaska, 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 Alaska project takes 4-12 weeks from planning to usable water.

What drives the cost of a well in Alaska

Depth
The biggest lever. Alaska wells average about 138 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 Alaska sits near 62 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
Alaska: Local permits (Anchorage, North Pole). 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.

Well drilling cost FAQ for Alaska

There is no single Alaska price - cost tracks depth, geology, and casing. As a starting point, water wells in Alaska average about 138 feet deep in our records, and at typical U.S. residential drilling rates that works out to roughly $3,700 to $5,600 for the drilling and casing alone. A complete water system (pump, pressure tank, treatment, permits) commonly runs $5,000-$15,000 nationwide. Get written quotes from at least two licensed Alaska drillers for a real number.

Typical U.S. residential rates run about $21 to $42 per foot for drilling and casing, with the lower end on shallow, small-casing wells and the higher end on shallow large-casing or hard-rock work. Most drillers also charge a setup or mobilization fee of a few hundred dollars. These are national averages, not Alaska-specific prices - your driller's rate depends on local rock and rig.

Across the 40,601 Alaska well records in DrillerDB, completed wells average about 138 feet deep. Depth is the single biggest cost lever: because drilling is priced largely per foot, a well twice as deep costs roughly twice as much to drill. Your site's actual depth depends on where the local aquifer sits, so a local driller reading nearby records is the best guide.

Permitting in Alaska: Local permits (Anchorage, North Pole) (18 AAC 72.100). Permit and inspection fees are usually a small part of the total, but they affect the timeline. A licensed Alaska contractor typically pulls the permit and folds it into the quote.

The drilled hole and casing are only part of it. A working system also needs a pump and pressure tank, wiring and a pitless adapter, a well cap and grouting, water testing, and often treatment for hardness, iron, or bacteria. Those add several thousand dollars on top of the drilling, which is why a complete private well system commonly runs $5,000-$15,000.
