Well depth by county in Connecticut

Total depth of domestic wells by county, Connecticut. Bar shows the middle half of wells; tick marks the median.
County Reports Median depth (ft) Middle half (ft) 0 to 530 ft
New London 730 340 240–450
Windham 675 300 220–400
Middlesex 418 380 300–510
Tolland 369 320 220–450
Fairfield 338 410 300–530
Litchfield 338 400 300–510
New Haven 264 400 290–530
Hartford 229 400 300–500

Median depth runs from 300 ft in Windham County to 410 ft in Fairfield County. At national rates that difference is worth about $5,300 at the midpoint estimate.

Where the money goes on a Connecticut well

Drilling is billed by the foot at $25–$75/ft, so the hole alone runs $6,400–$37,500 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 Connecticut

Water wells in Connecticut fall under Connecticut Department of Public Health (Private Well Program), with local health directors. Under the state Public Health Code, a private well is permitted by the local director of health, which means the town or health district. The code also sets the separating distances for new wells. A person must register annually with the Department of Consumer Protection as a well drilling contractor before drilling wells or installing pumps. The contractor files a completion report with the Department of Consumer Protection within 60 days after finishing a water supply well.

Groundwater and well construction in Connecticut

Cross-section of a 350 ft well with casing to 40 ft, the Connecticut median

Most Connecticut wells are drilled into bedrock, because thin glacial till covers much of the upland. Stratified drift valley deposits are the more productive aquifers.

A well at the Connecticut median reaches 350 ft with casing to about 40 ft. Public Health Code 19-13-B51d sets the separating distance between a new well and a sewage disposal system. The figure in the published materials differs by pipe type and well yield, so confirm it with the local health director.

USGS identifies radon as a major concern in Connecticut's crystalline-rock aquifers.

Common questions

How deep is a typical well in Connecticut?

Half of the 3,361 domestic wells reported in Connecticut from 2021–2025 are between 260 ft and 500 ft deep, and the median is 350 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 Connecticut?

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 $78/ft at a depth of 350 ft. Per-foot quotes rarely include the pump.

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

Under the state Public Health Code, a private well is permitted by the local director of health, which means the town or health district. The code also sets the separating distances for new wells. 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 Connecticut?

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.
