Well Drilling Cost in Maine: $30–$70/ft Price Guide (2026)

Maine has one of the highest rates of private well use in the country — about 45% of households rely on a private well for drinking water. The state’s rural character, granite bedrock, and limited municipal water systems make wells the default water source outside of Portland, Lewiston, and Bangor. Here’s what drilling a well costs in Maine in 2026.

Maine Well Drilling Costs at a Glance

Cost Factor	Range
Average total project cost	$12,624
Cost per foot	$30–$70
Average well depth	263 feet
Typical depth range	80–600 feet
Permit costs	$50–$200

Maine wells cost above the national average for the same reasons as its neighbor New Hampshire — hard crystalline bedrock that’s slow to drill and deep wells needed to hit productive fracture zones. If you’re familiar with New Hampshire well costs, expect similar pricing in Maine.

Cost Per Foot by Region

Southern Maine (Portland, Biddeford, Saco, Kennebunk, York)

• Typical depth: 200–400 feet
• Cost per foot: $30–$55
• Geology: Granite and metamorphic bedrock with some glacial sand and gravel near the coast

Southern Maine has the highest population density and the most competitive drilling market. Coastal properties may find glacial sand and gravel aquifers at shallower depths (80–200 feet), while inland hilltop properties drill into granite for 300+ feet. Expect $8,000–$16,000 for a complete system. The Portland metro area has municipal water, so most well drilling here is for properties in surrounding towns.

Midcoast and Downeast (Bath, Rockland, Belfast, Ellsworth, Bar Harbor)

• Typical depth: 200–500 feet
• Cost per foot: $35–$60
• Geology: Hardened schist and granite bedrock; thin glacial till overlay

The midcoast and Downeast regions have challenging drilling conditions — hard bedrock close to the surface with thin soil cover. Wells here tend to run deeper than southern Maine as fracture zones can be harder to locate. Budget $10,000–$22,000. Seasonal properties (vacation homes) are subject to the same construction standards as year-round residences.

Western Maine / Mountains (Bethel, Rangeley, Farmington, Rumford)

• Typical depth: 250–600 feet
• Cost per foot: $35–$70
• Geology: Deep granite and metamorphic bedrock

The western mountains have Maine’s deepest and most expensive wells. Massive granite formations yield water only through fracture intersections, and it may take considerable depth to find adequate flow. Access can be difficult on steep, wooded lots. Budget $12,000–$28,000+. Low-yield wells (under 3 GPM) are more common here than in other regions.

Central Maine / Kennebec Valley (Augusta, Waterville, Lewiston, Auburn)

• Typical depth: 150–350 feet
• Cost per foot: $30–$55
• Geology: Mix of glacial sand and gravel in valleys, bedrock on ridges

Central Maine benefits from productive glacial outwash deposits in the major river valleys — the Kennebec, Androscoggin, and Penobscot. Properties near these valleys can hit good water at 100–200 feet. Ridge and hillside properties revert to bedrock drilling. Expect $7,000–$15,000. This region has the most favorable drilling conditions in the state.

Northern Maine / Aroostook County (Presque Isle, Caribou, Houlton, Fort Kent)

• Typical depth: 150–400 feet
• Cost per foot: $30–$60
• Geology: Sedimentary and volcanic bedrock — different from southern Maine’s granite

Aroostook County’s geology differs from the rest of Maine — sedimentary rocks (sandstone, limestone) rather than granite, which can drill more easily. However, the remote location means fewer drillers serve the area, which can mean longer wait times and higher mobilization charges. Budget $8,000–$18,000. Cold winters (frost to 5+ feet) limit the drilling season more than in southern Maine.

What’s Included in the Cost

A typical Maine well drilling quote covers:

• Drilling and casing — steel casing through overburden, open borehole in bedrock
• Grout seal — cement seal between casing and bedrock
• Development — air-lifting to clear debris and test yield
• Well cap — sanitary seal and vent
• Well report — filed with the state as required

Not typically included (budget separately):

Additional Cost	Price Range
Submersible pump + installation	$1,200–$4,000
Pressure tank	$400–$1,500
Electrical hookup	$500–$1,500
Water line to house (below frost line)	$500–$3,500
Water testing	$150–$800
Water treatment system	$1,000–$6,000

Water lines must be buried below the frost line (4–5 feet in Maine), which adds to excavation costs compared to warmer states.

Maine Permits and Regulations

Well construction in Maine is regulated through local plumbing inspectors coordinated by the Maine Department of Health and Human Services.

Key requirements:

• Permit required — obtained through your town’s local plumbing inspector ($50–$200)
• Licensed driller required — all well drillers must be licensed by the Maine Well Drillers Commission. A separate pump installer license is also required. No homeowner exemption
• Well completion report — required after drilling, filed with the state
• Setback distances — minimum 100 feet from septic tanks and disposal areas, 25 feet from property lines, 50 feet from surface water (distances may vary by municipality)
• Water testing — not required by state law for private wells but strongly recommended, especially for arsenic and radon given Maine’s geology
• Reasonable Use doctrine — Maine follows reasonable use for groundwater rights, meaning you can use groundwater on your property as long as it doesn’t unreasonably interfere with neighbors’ wells

Water Quality Concerns

Maine’s bedrock geology creates specific water quality challenges very similar to neighboring New Hampshire:

• Arsenic — the most significant concern. Naturally occurring in granite and metamorphic rock. Maine estimates that 1 in 10 wells exceeds the EPA limit of 10 ppb, with higher rates in certain geological zones. Treatment costs $1,500–$4,000
• Radon — dissolved radon gas is common in bedrock wells throughout the state. Aeration systems cost $2,000–$5,000
• Uranium — found in some granite aquifers, particularly in southern and western Maine
• Manganese — causes staining and taste issues; common in both bedrock and sand/gravel wells
• PFAS — an emerging concern near former military bases (especially the former Brunswick Naval Air Station and Loring Air Force Base) and some agricultural areas where PFAS-contaminated sludge was applied as fertilizer. Maine has some of the strictest PFAS standards in the country
• Hardness — calcium and magnesium levels vary by geology but many Maine wells produce moderately hard water

Budget $150–$800 for comprehensive testing. At minimum, test for bacteria, nitrate, arsenic, radon, uranium, and manganese. Add PFAS testing ($200–$400) if you’re near known contamination areas.

Best Time to Drill

Maine’s climate creates a defined drilling season:

• April through November is the primary season. Ground thaws by mid-to-late April in southern Maine, May in northern Maine
• Winter drilling is technically possible in bedrock (granite doesn’t freeze) but snow cover, frozen access roads, and deep frost (4–5 feet) make it impractical for most sites
• Spring mud season (March–April) can make rural roads and properties impassable for heavy drill rigs
• Fall is ideal — dry ground, good access, moderate temperatures, and drillers are less backlogged than midsummer
• Book 6–10 weeks ahead in the busy May–September season

How to Save Money

1. Get 3+ quotes — prices vary significantly, especially between southern and northern Maine drillers. Get free estimates
2. Check Maine’s well records — search for nearby wells to estimate depth. Your town office or driller can help locate records
3. Ask about yield guarantees — in granite bedrock, low-yield wells are a real possibility. Some drillers offer to hydrofracture or re-drill at reduced cost if initial yield is inadequate
4. Budget for treatment from the start — with 1 in 10 wells exceeding arsenic limits, plan for $2,000–$4,000 in potential treatment costs rather than being surprised
5. Consider well location carefully — lower elevations near valley floors generally have shallower water tables than hilltop sites. A well site 100 feet lower in elevation could save thousands in drilling depth
6. Bundle drilling + pump — one contractor for the complete installation saves $500–$1,500 vs. separate companies

Frequently Asked Questions

How deep are most residential wells in Maine? The average is about 263 feet. Southern coastal Maine wells may run 150–300 feet. Western mountain wells often exceed 400 feet and can reach 600 feet. Central Maine valley wells are typically 100–250 feet.

Can I drill my own well in Maine? No. Maine requires all well construction to be performed by a licensed driller through the Maine Well Drillers Commission. A separate pump installer license is also required.

How much does a well cost in Maine vs. New Hampshire? Very similar — both states have granite bedrock, deep wells, and high per-foot costs. Maine averages about $12,624 vs. New Hampshire’s $14,400. The difference is mainly that NH wells average slightly deeper (300 ft vs. 263 ft).

Is arsenic in well water common in Maine? Yes. Maine estimates that about 10% of private wells exceed the EPA arsenic limit of 10 ppb. Arsenic is naturally occurring in the granite and metamorphic bedrock. Testing is essential before using any Maine well for drinking water.

What about PFAS in Maine well water? PFAS contamination is a growing concern in Maine, particularly near former military installations and agricultural land where PFAS-contaminated sludge was used as fertilizer. Maine has set some of the strictest PFAS standards in the country (20 ppt for individual compounds). If you’re in a known risk area, add PFAS testing to your water analysis ($200–$400).

How long does it take to drill a well in Maine? Drilling through granite takes 2–5 days for most residential wells. The complete project including pump, electrical, and plumbing takes 2–4 weeks.
