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

When New Hampshire 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 New Hampshire so you can evaluate quotes with confidence.

What’s Included in New Hampshire Per-Foot Pricing

Most New Hampshire 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 New Hampshire (New Hampshire Department of Environmental Services (NHDES), Water Division) — typically $50–$500

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

Casing Cost Per Foot in New Hampshire

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 New Hampshire with hard bedrock or deeper wells (typically the upper end of the 100–700 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 New Hampshire

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

0–200 feet: The most straightforward drilling. Standard rigs handle these depths easily; formations are usually softer. Rates stay at the $30–$48 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 New Hampshire’s range ($70/ft) or beyond. New Hampshire’s deepest wells are typically in the 600–700+ ft range.

Many New Hampshire 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 New Hampshire

New Hampshire’s bedrock is primarily Paleozoic and Mesozoic granite, gneiss, and schist that yield water only through fractures, making well yields variable and sometimes unpredictable. Glacial sand and gravel in river valleys provide better yields where available, but most residential wells are drilled into bedrock.

The geology summarized above is the primary driver of per-foot cost variation within New Hampshire. Areas with softer sedimentary formations drill faster and cheaper. Areas with limestone, granite, or volcanic rock require slower, more expensive methods. New Hampshire’s primary aquifer — the Fractured Crystalline Bedrock Aquifers / Stratified Drift Aquifers — sits at 50-150 feet in valley sand and gravel; 100-600+ feet in bedrock, depending on fracture zones, which directly affects how deep your well must go.

Total Well Cost Estimates in New Hampshire

Here’s what New Hampshire 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
300 ft (typical)	$9,000–$21,000	$11,500–$26,000
500 ft (deeper)	$15,000–$35,000	$17,500–$40,000
700 ft (deepest typical)	$21,000–$49,000	$23,500–$54,000

How to Compare Per-Foot Quotes

When you receive quotes from multiple New Hampshire 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. New Hampshire requires all water well contractors to be licensed by NHDES.

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

When to Drill in New Hampshire

April through November; granite bedrock makes winter drilling possible but access roads may be impassable

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 New Hampshire?

New Hampshire well drilling costs $30–$70 per foot in 2026, with $48 per foot as the average. Total cost depends on depth — a typical 300-foot well costs $9,000–$21,000 for drilling alone, plus $2,500–$5,000 for pump and connection.

Why is well drilling cost per foot different across New Hampshire?

New Hampshire’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 New Hampshire 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 New Hampshire?

In New Hampshire, residential well depths typically range from 100 to 700 feet, with 300 feet being the average. Your specific depth depends on local geology, target aquifer, and how productive nearby wells have been. The Fractured Crystalline Bedrock Aquifers / Stratified Drift Aquifers is New Hampshire’s primary residential aquifer, sitting at 50-150 feet in valley sand and gravel; 100-600+ feet in bedrock, depending on fracture zones.

Is it cheaper to drill a shallow well in New Hampshire?

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 700-foot well runs $21,000–$49,000. However, you can’t choose your well depth — it depends on where the productive aquifers are beneath your property.

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

Most New Hampshire 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 New Hampshire?

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.
