Cost Tip
Get quotes from 2-3 licensed drillers before deciding. Costs vary significantly by region and geology. Some Wyoming contractors offer "first 100 ft fixed price" packages, then charge per-foot rates for deeper drilling. Mountain areas often have harder rock requiring more time.
Timeline: From Decision to Drinking Water
Expect 3–6 weeks from your first call to potable water. SEO permitting is usually quick (1–2 weeks for domestic wells).
| Step | Duration | Notes |
|---|---|---|
| Finding contractor & planning | 1–2 weeks | Get bids from licensed drillers |
| SEO Permit approval (Form U.W.5) | 1–2 weeks | Domestic/stock use permits typically quick |
| Drilling & casing installation | 3–5 days | Varies by depth and geology |
| Pump installation & hookup | 1–2 days | Set pump, connect wiring, plumbing |
| Disinfection and flushing | 1–2 days | Chlorination per SEO standards |
| Water quality testing | 1–2 weeks | Lab analysis (bacteria, nitrates, etc.) |
| File Statement of Completion (U.W.6) | 30 days max | Driller or owner submits to SEO |
Permits & Process
Permit Required
Wyoming law (W.S. 41-3-930) requires a water rights permit from the State Engineer's Office before drilling any groundwater well. This applies to all wells, including domestic and stock wells.
Step-by-Step Process
- Engage a licensed driller. Wyoming law (W.S. 33-42-101) requires licensed water-well contractors, with an exemption for owners drilling on their own land (W.S. 33-42-103).
- File Form U.W.5. Submit an Application for Permit to Appropriate Groundwater to the State Engineer's Office. Your driller can help with this.
- Wait for approval. Domestic/stock well permits typically take 1–2 weeks to process.
- Call 811 for utility locates. Required before drilling begins.
- Drilling begins. Contractor drills to Wyoming's 2011 Water Well Minimum Construction Standards (casing, grouting, sealing).
- Install pump and equipment. Submersible pump, pressure tank, pitless adapter, and plumbing connections.
- Disinfect the well. Chlorination per SEO standards, flush thoroughly.
- File Statement of Completion (Form U.W.6). Driller or owner must file within 30 days of completion.
- Test water quality. Collect samples and have them analyzed by a certified lab.

Water Quality
Well water testing in Wyoming
The Wyoming DEQ Know Your Well program handles private well water quality in Wyoming. Wyoming recommends annual bacteria and nitrate testing; the state Department of Agriculture lab in Laramie (307-742-2984) analyzes private well samples.
Not sure what to test for? See our national guide to well water testing or order a certified lab test kit shipped to your door.
Important
Wyoming does not mandate water testing for private wells by law. However, Wyoming DEQ strongly recommends regular testing. Many contaminants are invisible, tasteless, and odorless.
Recommended Testing Schedule
- Annually: Bacteria (coliform/E. coli) and nitrates
- Every 3-5 years: Full chemical analysis (arsenic, metals, sulfate, TDS)
- After any event: Flooding, pump servicing, water taste/odor/color changes
- Before real estate transactions: Full water quality panel
Common Wyoming Water Quality Issues
Bacteria & Nitrates
Most common on agricultural plains. Caused by livestock waste, septic leakage, or surface runoff. Test annually for coliform, E. coli, and nitrates.
Arsenic
Found naturally in some Wyoming aquifers, especially in the Laramie Range foothills and Intermontane basins. Can exceed 10 µg/L EPA standard. Test every 3–5 years.
Hard Water & Minerals
Typical statewide. High calcium/magnesium causes scale. Some areas have elevated selenium, uranium, or radon. Iron/manganese staining is common.
Testing Costs
- Basic bacteria + nitrates: ~$150–$200
- Full chemical panel: ~$250–$400
- Certified labs: Use EPA Region 8-certified labs (see Wyoming Dept. of Health or county health departments)
Testing Resources
Teton County Health Department offers free/low-cost testing kits (307-732-8490). Other county health departments may have similar programs. The Wyoming Public Health Lab in Cheyenne also provides certified drinking water analysis (307-777-7431).
Maintenance & Troubleshooting
Annual Maintenance Checklist
- Test water for bacteria and nitrates
- Inspect wellhead cap and seal for cracks/damage
- Check pressure tank gauge (30-50 psi typical)
- Keep area around well clean (no livestock, chemicals within 100 ft)
- Shock chlorinate if recommended or after contamination
Warning Signs of Well Problems
- Sudden drop in water pressure or flow rate
- Pump running continuously or cycling frequently
- Cloudy, discolored, or odorous water
- Air sputtering from faucets
- New staining on fixtures (iron/manganese)
- Oil or gas odor in water
DIY vs. Professional
You can handle basic inspections, water testing, and filter changes yourself. Major repairs (pump replacement, casing work, depth changes) must be done by a licensed contractor per Wyoming law (W.S. 33-42-101).
Find a Licensed Driller
Wyoming generally requires a licensed water well contractor; W.S. 33-42-103 exempts owners drilling on their own land and certain pump work.
Search Licensed Drillers in Wyoming
Find Drillers Near You →How to Verify a Driller
- Ask for their Wyoming license number
- Verify at Wyoming Contractor Search
- Check license is current (3-year renewal cycle)
- Get 2-3 written quotes for comparison
- Ask for references from recent jobs
Unlicensed Work
Use a licensed contractor unless a W.S. 33-42-103 exemption applies. Owners may drill on their own land, and separate exemptions cover some pump work. Work must still meet permitting and construction standards to avoid groundwater contamination issues. A violation of the licensing act is a misdemeanor with a fine up to $1,000, up to six months in jail, or both (W.S. 33-42-117). Unlicensed work can also leave the well out of compliance with the State Engineer's construction standards.

Do I need a permit to drill a well in Wyoming?
Yes. Wyoming law (W.S. 41-3-930) requires a water rights permit from the State Engineer's Office before drilling any groundwater well. You must file Form U.W.5 (Application for Permit to Appropriate Groundwater) before drilling begins. Processing typically takes 1–2 weeks for domestic/stock wells.
How long does it take to drill a well in Wyoming?
The complete process from planning to potable water typically takes 3–6 weeks. SEO permit approval takes 1–2 weeks, drilling takes 3–5 days, and water testing adds another 1–2 weeks. After completion, the Statement of Completion (Form U.W.6) is due within 30 days.
Is water testing required for private wells in Wyoming?
Wyoming does not mandate water testing for private wells by law, but it is strongly recommended by Wyoming DEQ. At minimum, test annually for bacteria (coliform/E. coli) and nitrates. Test for arsenic, metals, and other contaminants every 3–5 years or after any water quality change.
How do I find a licensed well driller in Wyoming?
Wyoming law (W.S. 33-42-101) requires licensed contractors unless a statutory exemption applies, including an owner drilling on their own land. Search the Wyoming Water Well Contractors Licensing Board database at wwcbcontractorsearch.wyo.gov to verify driller licenses. The SEO cannot recommend specific companies but maintains the contractor search system.
