A home tour cannot show the condition inside a buried sewer service line. Local utilities generally place responsibility for that private pipe on the property owner.
This Northern Colorado sewer scope inspection guide explains what buyers can learn, how municipal responsibility differs from private responsibility and which questions to ask before deciding whether to order an inspection. It is general information, not plumbing, insurance or legal advice.
Understand which sewer pipe belongs to the owner
The public utility operates the sewer main, but the pipe connecting a home to that main is commonly private. The exact dividing point and service provider must be confirmed for the property.
Fort Collins Utilities’ customer support page says the property owner owns and maintains the sewer service pipe between the house and the sewer main in the street. The City cleans blockages in its main; the owner pays cleanup and repair expenses when the blockage is between the home and main, including street or driveway damage associated with that private problem.
The City of Greeley’s wastewater collection page similarly says residents are responsible for their service line and should contact a private sewer-maintenance company for a personal-line issue.
Loveland Water and Power states that property owners are responsible for wastewater service lines from the property to the point where the line taps into the main. Windsor’s water and sewer page directs customers to Town utility resources; the Town’s published utility guidance places the private sewer line on the homeowner through its connection with the main.
Those examples show the regional pattern, but they do not identify the provider or boundary for every address. Some properties use a sanitation district, shared line, HOA-managed system or septic system instead of the city named in the mailing address.
Know what a sewer scope can show
A sewer scope typically uses a small camera introduced through an accessible cleanout or other approved entry point. The operator advances it through the private line and records visible conditions.
A useful inspection may identify:
- Roots entering joints or cracks. - Accumulated grease, debris or scale. - Offset or separated joints. - Cracks, holes or deteriorated pipe material. - Low areas where water remains in the line. - Obstructions or sections the camera cannot pass. - The approximate distance of a visible concern from the access point.
A camera inspection does not expose every buried condition, guarantee future performance or necessarily locate the pipe precisely. Water, debris and access problems can obscure defects. Ask what was visible and whether another evaluation is recommended.
Consider the property, not just its age
Older homes may have pipe materials and mature landscaping that deserve review, but newer construction is not automatically problem-free. Installation debris, soil movement or improper slope can affect a newer line.
Other reasons to discuss a scope include:
- Large trees near the probable service route. - A history of slow drains, backups or repeated cleaning. - An addition or major site work. - A driveway, patio or landscaping over the likely route. - A shared or common private line serving attached homes.
Base the decision on the specific home, available records and qualified professional advice.
Ask for the video and a clear written result
Before scheduling, ask whether the provider will supply the full video, written report and still images. Confirm the entry point, expected segment and camera distance.
After the inspection, ask:
1. Was the camera able to reach the public connection or another clear endpoint? 2. Were all visible defects labeled with distance and orientation? 3. Did water or debris prevent a complete view? 4. Is cleaning recommended before a second look? 5. Does a licensed plumber need to evaluate repair options? 6. Is there evidence of an active blockage or only a maintenance concern?
Avoid reducing the result to “pass” or “fail.” A documented condition, its location, repair access and professional recommendations are more useful than a simple label.
Research records without assuming they are complete
Utility records can add context, but absence of a record is not proof that a problem never occurred. Greeley provides an especially useful example: its Wastewater Collection Division says it has tracked sewer emergency calls by property since 1974 and can tell a prospective purchaser about recorded issues and whether the City or a private owner corrected them.
Greeley cautions that its data may show the connection to the public main, not the route across private property, and older records may be incomplete. Verify records with the utility, then compare them with the inspection.
Ask the seller for invoices, permits, cleaning records, replacement documents and any transferable warranty. Review shared-line or easement responsibilities with appropriate professionals.
Separate repair questions from negotiation decisions
If the scope identifies a concern, obtain a qualified plumber’s explanation before estimating cost or choosing a response. Repair options can vary based on pipe material, depth, location, access, municipal requirements and whether excavation affects a street, sidewalk or landscaping.
The inspection itself does not determine who must pay in a real estate transaction. Contract deadlines, objection rights and negotiation choices depend on the signed agreement and professional advice. Keep the video, report, estimates and communications together so the decision is based on the same documented information.
Check insurance and ongoing maintenance separately
Home insurance does not automatically cover every service-line failure or backup. Loveland Water and Power advises homeowners to ask their insurance agent about water and wastewater damage. Buyers can ask about service-line and sewer-backup coverage, limits and exclusions.
After purchase, protect the line by keeping fats, oils, grease and wipes out of drains. Greeley specifically warns that even products labeled “flushable” contribute to clogs.

Northern Colorado sewer scope FAQ
Is a sewer scope part of a standard home inspection?
Not necessarily. Ask the inspector what is included and whether a separate sewer-camera specialist or plumber is needed.
Does a clear video guarantee the line will not fail?
No. A scope documents visible conditions at the time of inspection and has access and visibility limits.
What if the home uses a septic system?
Municipal sewer-main responsibility does not apply. Septic properties require different records, tank, absorption-area and transfer-rule research.
