Buying a home on public water and sewer is different from buying a property that depends on a private well, a septic system or both. The house may feel similar, but the buyer is taking responsibility for private infrastructure that needs its own records, inspections and long-term maintenance plan.
For a well, start with the legal and practical basics. Colorado's Source of Water Addendum identifies whether the property uses a well, a water provider or another source, and it provides a place for the well permit number. Buyers should verify the current permit, understand the permitted use and make sure the ownership information can be properly updated after closing when required.
Water quantity and water quality are separate questions. A well can exist legally and still produce water with characteristics a buyer wants to understand. Depending on the property and intended use, buyers may consider flow or production information, water-quality testing and expert review of the well equipment and pressure system.
Septic systems are regulated locally under Colorado's statewide on-site wastewater framework. CDPHE notes that systems serving 2,000 gallons per day or less are permitted through local counties or public health agencies, and some jurisdictions use transfer-of-title inspection programs. That means the exact requirements can change by county.
A septic review can include the tank, treatment components, absorption field, pumping history, permits, location and signs of failure or deferred maintenance. Buyers should not assume a normal home inspector is performing a complete septic evaluation unless that service is specifically included.
The right question is not whether a well or septic system is good or bad. Many Colorado properties depend on them successfully for decades. The question is whether the specific systems are documented, functioning, appropriate for the property and understood before closing.
