Well Drilling Costs in North Dakota

A complete private well system in North Dakota typically costs $5,000–$15,000, depending on depth, geology, and equipment. Typical drilling costs run $20–$50 per foot.

2024-2025 North Dakota well drilling cost estimates
ComponentTypical CostNotes

Timeline: From Decision to Drinking Water

Expect 4–8 weeks from your first call to potable water. No state permit delays, but drilling season and contractor availability matter.

Typical North Dakota well drilling timeline
StepDurationNotes
Hire Licensed Contractor1–2 weeksVerify license with ND Board of Water Well Contractors
Site Evaluation1 dayDriller evaluates location, geology, contamination sources
Drilling & Construction1–2 daysDrill, install casing, screen, cement grout annulus
Pump Installation1 daySet pump, install pitless adapter, connect piping
Disinfection & Development1 dayShock chlorinate, purge sediments
Water Testing1–2 weeksCollect samples after chlorination, wait for lab results
Final Plumbing Connection1 dayConnect to home plumbing, set pressure
Seasonal Considerations
Winter drilling challenges: Ground freezes 5–6+ feet deep in ND winters. Drilling hardware and fluids must be winterized. Many drillers prefer spring/summer/fall. Plan accordingly if building a new home.

Permits & Process

Do You Need a Permit?

No State Permit Required

North Dakota does not require a state-wide location permit for private domestic wells (ND DEQ).

  • Faster timeline (no permit wait)
  • Licensed contractor handles documentation
  • Check local county/city requirements
Must Use Licensed Contractor

State law requires licensed water well contractors per NDCC 43-35-11 (ND Board).

  • Driller must be certified by ND Board
  • Contractor files Well Driller's Report (SFN 60273)
  • Homeowners may drill own well but most hire pros

Step-by-Step Process

  1. Hire a licensed contractor. Contact the ND Dept. of Water Resources or State Board of Water Well Contractors to find licensed drillers.
  2. Site evaluation. The driller visits to locate a suitable drill site (considering geology and contamination sources).
  3. Local approvals. While ND has no statewide permit, the driller will obtain any required local permits (varies by county/municipality).
  4. Drilling & construction. The crew drills the hole and installs casing/screen per ND Admin. Code 33.1-18-01 (water well construction rules). Cement grout is placed in the annulus.
  5. Pump installation. A submersible pump and wiring are installed; a pitless adapter allows underground discharge. Pressure tank and control switch are mounted (usually in basement).
  6. Disinfection. The driller sanitizes the well with chlorine and "develops" it (purging fine sediments).
  7. Documentation. The driller files the Well Driller's Report (SFN 60273) with ND Dept. of Water Resources to document depth, construction details, static water level, geologic log, etc.
  8. Final plumbing tie-in. The home's plumbing is connected, and system pressure is set.
  9. Water testing. Before drinking, have the well tested for safety (see below).
Well Casing Standards
ND law requires well casing to extend at least 12 inches above ground(NDSU Extension) with a sealed cap to prevent contamination.

Water Quality

Important
State law does not mandate specific tests for private wells. However, testing is strongly recommended. At minimum, test for coliform bacteria and nitrates every 1–3 years(NDSU Extension). Many dangerous contaminants (arsenic, nitrates) are invisible and tasteless.

Recommended Testing Schedule

Common North Dakota Water Quality Issues

Nitrates

Elevated in agricultural areas (Red River Valley, eastern ND). EPA limit: 10 mg/L. High nitrates cause "blue baby syndrome." (ND DEQ)

Regions: Red River Valley, intensively farmed areas

Treatment: Reverse osmosis (RO) or ion-exchange

Arsenic

Naturally occurring in deep aquifers. Many western/central ND wells exceed 10 µg/L EPA limit. Long-term exposure is carcinogenic. (NDSU Extension)

Regions: Western & central ND (deep glacial/bedrock aquifers)

Treatment: Anion-exchange filter, oxide-coated media, or RO

Coliform Bacteria

Shallow wells or older dug wells may show bacteria if poorly sealed. Any positive test requires treatment. (NDSU Extension)

Regions: Statewide (shallow wells)

Treatment: UV disinfection, continuous chlorinator, shock chlorination

Iron & Manganese

Common statewide. Iron >0.3 mg/L, manganese >0.05 mg/L cause staining and metallic taste. Not acute health hazards. (NDSU Extension)

Regions: Statewide

Treatment: Water softener, oxidizing filter, iron-specific media

Hardness

ND water is typically "hard" (high calcium/magnesium). Causes scale and soap issues but not unsafe.

Regions: Statewide

Treatment: Water softener (ion-exchange)

Oilfield Impacts

NW ND (Bakken region) may have salinity, chloride, hydrocarbons from spills. Test for chloride, oil & grease, VOCs if near active wells. (ND DEQ)

Regions: NW ND (Bakken oil region)

Treatment: RO for salinity; activated carbon for organics

Arsenic & Nitrate Alert
  • Arsenic: Parts of western and central ND have naturally high arsenic in deep aquifers. EPA limit: 10 µg/L. Long-term exposure is carcinogenic (NDSU Extension).
  • Nitrates: Agricultural areas (Red River Valley, eastern ND) often have elevated nitrates from fertilizers. EPA limit: 10 mg/L nitrate-N. High nitrates can cause "blue baby syndrome" (ND DEQ Groundwater Monitoring).

Water Testing Costs & Labs

Homeowners pay for all private well tests. The ND Dept. of Health and Human Services lab charges about $27 for a standard bacterial kit. Other tests (arsenic, nitrate, metals) may run $50–$100 each at certified labs.

Maintenance & Troubleshooting

Annual Maintenance Checklist

Warning Signs of Well Problems

  • Sudden changes in water quality (cloudy, rusty, sulfur smell)
  • Low pressure or flow (pump failure, silted well, or pressure tank issue)
  • Frequent pump cycling or electrical overloads (waterlogged tank)
  • Grinding or unusual noises from the pump (wear or debris)
  • Persistent foul odors after chlorination (contaminated aquifer)
  • Visible corrosion or damage to plumbing fixtures
DIY vs. Professional
You can handle minor tasks: pressure tank and filter cartridge replacement, chlorination, visual inspections. Call a licensed well contractor for major work: drilling a new well, replacing a pump or motor, installing a new pressure tank, or repairing pitless units. ND law requires a certified driller for drilling or pump-install activities (ND DEQ).

Find a Licensed Driller

North Dakota law requires a licensed water well contractor for all well drilling work (NDCC 43-35-11).

Frequently Asked Questions

A complete well system in North Dakota typically costs $5,000–$15,000 for drilling and casing, plus $1,000–$3,000 for the pump system. Drilling costs average $20–$50 per foot depending on depth and geology. Additional costs include water testing ($25–$100 per test) and minimal permit fees.

North Dakota does not require a state well permit for private domestic wells. However, you must hire a licensed water well contractor (per NDCC 43-35-11), and the contractor must file a Well Driller's Report (SFN 60273) with ND Dept. of Water Resources within 30 days of completion. Check for any local county requirements.

From decision to potable water typically takes 4–8 weeks. Actual drilling often takes 1–2 days. Including scheduling, pump installation, disinfection, and water testing, expect roughly 4–8 weeks total. Busy seasons or complex sites can extend this timeline.

Yes, naturally occurring arsenic is a concern in parts of North Dakota. Many deep wells in western and central ND contain arsenic above the EPA limit (10 µg/L). Long-term arsenic exposure causes cancers and other health issues. Testing is strongly recommended, especially for deep wells.

Test for coliform bacteria and nitrates every 1–3 years at minimum. Test for arsenic, iron, manganese, and other minerals every 3–5 years. Always test after any changes in water quality (taste, color, smell) or after flooding, well repairs, or contamination events in your area.
