| Registration Fee | $25 | Optional domestic well registration |
| Total Project | $4,000–$15,000+ | Typical 150 ft well ~$5,000–$9,000 |
Timeline: From Decision to Drinking Water
Expect 4–12 weeks from your first call to potable water. Since no permit is required for domestic wells, the timeline is faster than many states.
| Step | Duration | Notes |
|---|---|---|
| Planning & Driller Selection | 1–4 weeks | No permit required for domestic use (SDCL 46-5-8) |
| Drilling & Casing | 1–3 days | DANR: "Unless you are drilling your own well, you need to hire a well driller who is licensed to construct wells in South Dakota" |
| Pump & Tank Installation | 0.5–1 day | Driller or pump contractor installs equipment |
| Disinfection & Flushing | 1 day | Shock chlorination per ARSD 74:02:04 |
| Water Quality Testing | 4–7 days | Required by law; lab turnaround time |
| Connection to Home | 1 day | Plumbing hookup and final testing |
| Driller Report Filing | Within 30 days | Driller files completion report with DANR |
Permits & Process
Do You Need a Permit?
South Dakota has no permit requirement for ordinary domestic wells (single-family household use) per SDCL 46-5-8. However, larger or commercial wells require a water-right permit.
Single-family household wells need no water-right permit.
- No state permit fees
- Optional $25 registration available
- DANR: "Unless you are drilling your own well, you need to hire a well driller who is licensed to construct wells in South Dakota"
- Faster timeline overall
DANR: "even domestic use of water requires a permit if your water use exceeds either 25,920 gallons per day or a peak pump rate of 25 gallons per minute." Any non-domestic use needs a permit.
- Irrigation, commercial, industrial, institutional, recreation; municipal and rural water systems above 18 gpm. DANR: "It should also be noted that water distribution systems using 18 gallons per minute or less do not need to get a water right permit. Water distribution systems include municipalities, rural water systems, suburban housing developments, etc."
- ~2 month permit processing
- Application to DANR Water Rights
- Public notice required

Water Quality
Well water testing in South Dakota
The South Dakota Department of Health laboratory (with DANR) handles private well water quality in South Dakota. South Dakota recommends annual bacteria and nitrate testing; DANR maintains the list of certified drinking water labs.
Required testing: Every new domestic well drilled in South Dakota requires a water sample submitted to the SD Health Lab or an approved lab (1989 Centennial Environmental Protection Act).
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.
Required & Recommended Testing
- Required for new wells: Coliform bacteria, nitrate (as nitrogen), sodium, sulfate, conductivity
- Recommended initially: Arsenic, iron, manganese, hardness, pH
- Annual testing (recommended): Bacteria and nitrate. DANR: "It is recommended that the bacteriological quality of the water be retested at least annually. After heavy rains, snow melt, or flooding in the area of your well, a sample of water should be submitted for at least a bacteriological and nitrate analysis"
- After any event: Flooding, well repairs, taste/odor changes
Common South Dakota Water Quality Issues
Arsenic
Elevated arsenic found in western SD (Black Hills, mineralized rock areas) due to natural geology. EPA limit is 10 µg/L. Test before drinking.
Nitrate
High nitrate common in eastern SD and James River basin due to agricultural fertilizers. Levels over 10 mg/L are unsafe for infants.
Iron & Manganese
Many SD aquifers have iron/manganese-rich water causing staining on fixtures and clothing. Not a health hazard but requires filtration.
Treatment Options
- Bacteria: Shock chlorination, UV disinfection, or chlorination system
- Arsenic: Reverse osmosis (RO) or iron oxide adsorptive filters
- Nitrate: RO or ion-exchange filters (do not boil—concentrates nitrate)
- Iron/Manganese: Oxidation filters, water softeners, or greensand filters
- Hardness: Water softeners (ion-exchange systems)
Maintenance & Troubleshooting
Annual Maintenance Checklist
- Test water for bacteria and nitrate (annually)
- Check pressure tank and gauge (30-50 psi typical)
- Inspect wellhead seal and cap
- Flush sediment through outdoor spigot
- Replace filter cartridges per manufacturer schedule
- Shock chlorinate (every 1-3 years or after contamination)
Warning Signs of Well Problems
- Rusty brown water or black flecks (iron/manganese or corrosion)
- Blue-green staining (copper pipe corrosion)
- Sudden sediment or cloudiness (sand intrusion)
- Rotten-egg odor (hydrogen sulfide gas)
- Salty taste (chloride or softener issues)
- Declining flow rate or sputtering faucets (falling water level or pump failure)
- Pressure gauge reads zero or pump runs continuously
Find a Licensed Driller
DANR: "Unless you are drilling your own well, you need to hire a well driller who is licensed to construct wells in South Dakota. It is highly recommended that you use a licensed well driller unless you are capable of constructing your own well in accordance with the state well construction standards."
