Where the money goes on a Maine well

Drilling is billed by the foot at $25–$75/ft, so the hole alone runs $5,000–$31,500 at the depths above. Casing, the steel or PVC pipe that lines the upper borehole, adds $400–$1,800 at $10–$45/ft. Rig setup is a flat $600–$2,500.

The pump, pressure tank, and trench to the house add $2,500–$10,800 on top of the hole. A quote that looks low next to the range above often leaves those three out, so ask for it itemized.

Permits and driller licensing in Maine

Water wells in Maine fall under Maine Water Well Commission and Maine Geological Survey. A Maine Drinking Water Program presentation describes private drinking water wells as largely unregulated, with no state permit required. Town requirements may still apply. The Maine Water Well Commission licenses well drillers, and a master driller needs a minimum of 3 years of drilling experience. Maine law requires the well drilling company to report each new, deepened or dry well to the state geology division within 30 days.

USGS describes New England's crystalline-rock aquifer and its valley-fill sand and gravel deposits as the main sources of ground water in the region.

A well at the Maine median reaches 300 ft with casing to about 40 ft.

Common questions

How deep is a typical well in Maine?

Half of the 25,566 domestic wells reported in Maine from 2016–2025 are between 200 ft and 420 ft deep, and the median is 300 ft. Your county can sit well above or below that, so check the county table on this page before you compare quotes.

How much does it cost per foot to drill a well in Maine?

Drilling alone runs $25–$75/ft on the rates we compiled. Spread across a whole finished well, including casing, pump, tank, and hookup, the midpoint estimate works out to about $82/ft at a depth of 300 ft. Per-foot quotes rarely include the pump.

Do you need a permit to drill a well in Maine?

A Maine Drinking Water Program presentation describes private drinking water wells as largely unregulated, with no state permit required. Town requirements may still apply. The driller usually files the paperwork, but the permit is tied to your property, so ask for a copy.

How much do a well pump and pressure tank add in Maine?

An installed submersible pump with wire and drop pipe runs $1,000–$4,000, and a pressure tank with its switch runs $500–$1,800. Together they are often the line items missing from a drilling quote, so a quote for the hole alone will look $3,700 cheaper than a finished well.
