* 7 counties have fewer than 30 reports. Estimates there use the statewide figures.
Median depth runs from 40 ft in Otero County to 700 ft in Jefferson County. At national rates that difference is worth about $41,200 at the midpoint estimate. 7 of 64 counties have fewer than 30 reports; the calculator uses the statewide figure for those.
Where the money goes on a Colorado well
Drilling is billed by the foot at $25–$75/ft, so the hole alone runs $5,000–$37,500 at the depths above. Casing, the steel or PVC pipe that lines the upper borehole, adds $2,000–$9,000 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 Colorado
Water wells in Colorado fall under Colorado Division of Water Resources (Office of the State Engineer). A new domestic well needs a well permit from the State Engineer's Office, which is part of the Division of Water Resources. The permit for an exempt household well is issued under C.R.S. 37-92-602. The contractor, authorized individual, or private driller files a Well Construction and Yield Estimate Report with the State Engineer within 60 days after the well is completed. The permit or filing fee runs $100.
Groundwater and well construction in Colorado
Eastern Colorado draws on the High Plains aquifer and the four-aquifer Denver Basin system along the Front Range. Western Colorado sits on the Colorado Plateaus aquifers, whose water quantity and quality are highly variable.
A well at the Colorado median reaches 340 ft with casing to about 200 ft. The state construction standards keep a well at least 100 feet horizontally from the nearest existing source of contaminants such as a leach field, with variances possible.
Colorado State University Extension advises anyone drinking from a private well to have the water tested by a qualified lab for nitrate each year, and to retest every three to six months if the result is high.

Common questions
How deep is a typical well in Colorado?
Half of the 28,835 domestic wells reported in Colorado from 2016–2025 are between 200 ft and 500 ft deep, and the median is 340 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 Colorado?
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 $91/ft at a depth of 340 ft. Per-foot quotes rarely include the pump.
Do you need a permit to drill a well in Colorado?
A new domestic well needs a well permit from the State Engineer's Office, which is part of the Division of Water Resources. The permit for an exempt household well is issued under C.R.S. 37-92-602. Expect a fee of $100. 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 Colorado?
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.
