* 20 counties have fewer than 30 reports. Estimates there use the statewide figures.

Median depth runs from 50 ft in Grant County to 420 ft in Ottawa County. At Oklahoma rates that difference is worth about $25,200 at the midpoint estimate. 20 of 77 counties have fewer than 30 reports; the calculator uses the statewide figure for those.

Where the money goes on a Oklahoma well

Drilling is billed by the foot at $50/ft, so the hole alone runs $6,000–$11,300 at the depths above. Casing, the steel or PVC pipe that lines the upper borehole, adds $1,200–$5,300 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 Oklahoma

Water wells in Oklahoma fall under Oklahoma Water Resources Board, Well Driller and Pump Installer Licensing Program. Oklahoma law requires no OWRB permit for domestic groundwater use, which covers household purposes, farm animals and irrigation of up to three acres. A permit is required if the water will serve any other purpose. The OWRB licenses firms that install well pumps or drill or plug commercial, test, monitoring, geotechnical and heat exchange wells, and its fact sheet does not list domestic wells in that group. A license requires two years of qualifying experience and a passing score of 70% on the Board's test. Licensees file a well completion report (well log) with the OWRB within 60 days after finishing a new well, online or by mail. The permit or filing fee runs $0.

Groundwater and well construction in Oklahoma

Well cap Submersible pump Casing to about 120 ft Total depth about 180 ft Soil and loose rock Open hole in rock
Cross-section of a 180 ft well with casing to 120 ft, the Oklahoma median

A well at the Oklahoma median reaches 180 ft with casing to about 120 ft, a model assumption because the records here do not report casing. OWRB rules treat septic systems as pollution sources and keep a new well at least 50 feet from them, 75 feet if the well is level with the source and 100 feet if it is down-gradient.

The Oklahoma DEQ advises testing private well water every year for total coliform bacteria, nitrate and nitrite, conductivity and pH.

Common questions

How deep is a typical well in Oklahoma?

Half of the 14,852 domestic wells reported in Oklahoma from 2016–2025 are between 120 ft and 230 ft deep, and the median is 180 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 Oklahoma?

Drilling alone runs $50/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 $114/ft at a depth of 180 ft. Per-foot quotes rarely include the pump.

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

Oklahoma law requires no OWRB permit for domestic groundwater use, which covers household purposes, farm animals and irrigation of up to three acres. A permit is required if the water will serve any other purpose. Expect a fee of $0. 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 Oklahoma?

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.
