Sewer Line Replacement in Denver, CO

When replacement beats another repair

• The camera shows cracks, offsets or root entry at many joints, not just one
• Part of the line has collapsed or flattened
• Long sections sag and hold standing waste
• Older pipe material has corroded or broken down throughout the run
• You have paid for repeated clearing or patching and the backups keep coming

Why age matters in Denver

About 55.5% of Denver homes were built before 1980, and the median year built is 1975. Clay sewer laterals and cast iron building drains can come up in houses from that era. Both materials can last a long time, but by the time several joints are leaking or packed with roots, one full replacement can cost less over time than a string of repairs.

Three ways to replace the line

Not every line qualifies for trenchless work. A collapsed or badly bellied pipe usually has to be dug up. A good plumber will tell you if the footage rules out a less invasive option.

The city side and the private side

Denver Wastewater Management, part of the Department of Transportation and Infrastructure, runs the public sewer. The pipe from the house to the city main is generally a private plumbing job, but where the new line ties into the public system can involve the city. Before work near the street or the main connection, check with Wastewater Management about your address, and ask the plumber which permits they will pull.

Questions to ask before signing

1. Can I see the camera video and the marked location of each defect?
2. Which method do you recommend, and why not the others?
3. Does the price include permits, restoring the surface and a final camera pass?
4. What pipe material goes in, and what warranty comes with the work?

What sets the price

Line length and depth, the replacement method, what has to be removed and restored on top, how the connection to the main is made, and permit fees all shape the cost.
