Denver Sewer Repair Resource: An Independent Homeowner Guide
A practical, source-based starting point for Denver homeowners who want to understand sewer inspection questions, compare repair methods, and prepare for honest conversations with licensed professionals. This site is an independent information resource, not a contracting company.
Know your responsibility first. According to the City and County of Denver, Department of Transportation and Infrastructure (DOTI), the city is responsible only for main public sewers. A property’s private tap/service line is the property owner’s responsibility. For locating a private sewer tap or service line, the city recommends hiring a licensed plumbing company.
Compare Repair Methods
Review general descriptions of common approaches, including cured-in-place pipe (CIPP) relining and pipe bursting, with honest notes on what remains property-specific and unverified for Denver.

What this site is for
This resource exists to help Denver homeowners ask better questions before work begins. It does not provide emergency response, prices, contractor recommendations, or legal advice. Every page is grounded in publicly available sources, and where facts are not yet verified, the site says so plainly.
What to do if you suspect a sewer backup
DOTI’s Wastewater Management Division asks residents to report a sewer backup by calling (303) 446-3400. If the problem is in the city line, Wastewater personnel service it. If the problem is in the private line, the owner is responsible for contacting a plumber and repairing the damage. The city also advises against flushing disposable diapers, baby wipes, and feminine hygiene products, and against pouring grease into drains, because these clog sewer lines. Roots are drawn into sewer lines by moisture, warmth, and nutrients, and can penetrate cracks or pinholes and eventually clog the line.
What the city and Denver Water cover
DOTI’s Wastewater Management Division builds, operates, and maintains Denver’s sanitary sewer and storm drainage systems, maintaining more than 1,525 miles of sanitary sewers and 793 miles of storm drainage facilities. Denver Water is responsible for maintaining and replacing water mains throughout its service area, while property owners are responsible for the water service lines and meter pits at their service address. Denver Water is not responsible for water damage caused by a property’s service line or internal plumbing, and notes that such damage may or may not be covered by a typical homeowner’s insurance policy. Denver Water advises contacting an insurance agent to verify coverage.
Why sewer overflows matter
The U.S. Environmental Protection Agency (EPA) describes a sanitary sewer overflow (SSO) as an occasional release of raw sewage that can contaminate waters, back up into homes, cause property damage, and threaten public health. Possible causes include blockages, line breaks, sewer defects that let stormwater and groundwater overload the system, power failures, improper sewer design, and vandalism. EPA estimates there are at least 23,000 to 75,000 SSOs per year in the U.S., not including sewage backups into buildings. Understanding the difference between public and private lines is the first step in knowing who to call.
