Anyone interested in buying land in Colorado should familiarize themselves with well permits. Building a well requires specific permits and testing to ensure a safe water supply. Additionally, those investing in land with an existing well or looking to abandon or destroy a well must adhere to local regulations. This guide provides a concise overview of what you need to know about well permits in Colorado.
Water Access for Properties Without City/County Connections
If a property isn’t connected to a city or a county water supply ( Montezuma or Mancos Rural Water), it still needs water for drinking, bathing, and laundry. Larger properties (over 35 acres) may require a well for irrigation or livestock, typically tapping into groundwater. In Colorado, most residential wells are classified as “exempt” and require a permit.
Permitting for Exempt Wells
Wells are classified as “exempt” or “non-exempt” under Colorado law. Most homeowners deal with exempt wells, which do not need an augmentation plan.
- Household-use-only wells (for properties under 35 acres) can only supply indoor water.
- Domestic use wells (for properties over 35 acres) can supply water for up to three households and irrigate up to 1 acre of lawn and garden.
Checklist for Buying a Home with an Existing Well
Before purchasing a home with a well, buyers should:
- Check Existing Permits: Use the Colorado Division of Water Resources tools to verify permits. Wells drilled before May 8, 1972, may not have permits.
- Inquire About Well Capacity: A household generally needs about 75 gallons of water per person daily. A pump test can determine the well’s output.
- Assess Water Quality: Ensure the water is safe for consumption. Contact the Colorado Department of Public Health for lab testing options.
Considerations for Drilling a New Well
If no well exists, buyers can drill one. Key considerations include:
- Check for Previous Permits: Look for any prior permit attempts to avoid issues.
- Space Requirements: Ensure there’s enough distance from the well to the septic system (50 feet) and other contaminants (100 feet).
- Choose a Reliable Contractor: Verify licenses and reputation before hiring a well driller.
Managing Abandoned or Under-Performing Wells
Unused wells should be abandoned to prevent contamination. If a well is under-producing, a professional may recommend drilling deeper.
