# Municipal Sewer Line Repair in Denver, CO

Denver Sewer and Water performs municipal and mainline sewer work for districts, agencies, and the contractors who serve them, including mainline repair, trenchless solutions, and emergency response. We are a private contractor available for this work. We are not Denver Water or the City and County of Denver.

- Mainline repair and replacement.
- Trenchless methods that limit street and traffic impact.
- Emergency mobilization for public-side failures.
- Experience alongside city planners and engineering teams.

## Mainline Failures Carry Public Consequences

A failing municipal sewer line does not affect one property. It affects a block, a corridor, or a lift station, and it usually fails under pavement where access is the hardest part of the job.

Public-side work also carries obligations a residential repair does not: traffic control, notification, permitted restoration, and documentation that has to survive review.

- Mainline cracks, offsets, and collapses under roadway.
- Infiltration and inflow driving treatment volume up.
- Aging clay or concrete mains in older service areas.
- Manhole and connection deterioration.
- Repeat surcharge complaints along one segment.

## Condition Assessment Before Capital Spending

On public infrastructure, inspection is not just diagnosis, it is the record that justifies the spend. We camera the segment, locate it, and report condition in a form that supports a repair decision.

That record also separates the segments that need replacement now from those that can be lined or monitored on a longer horizon.

- Segment-by-segment camera assessment.
- Depth and alignment locating under pavement.
- Condition documentation for planning and budgeting.

## How Municipal Sewer Work Is Handled

1. **Define the Segment and the Constraints** We confirm the affected run, the surface conditions, traffic requirements, and any notification obligations before mobilizing.
2. **Assess and Report** Inspection results are documented so the responsible agency or engineer can review the recommendation.
3. **Select the Least Disruptive Method** Lining and trenchless replacement are evaluated first because closing a street is the most expensive part of most mainline projects.
4. **Repair, Restore, and Document** Work is completed with proper compaction and surface restoration, and closeout documentation goes back to the client.

## How Municipal Sewer Projects Are Priced

Mainline pricing is driven by pipe diameter, depth, length of the run, traffic control, dewatering, and pavement restoration requirements.

We scope these projects in writing and flag the cost drivers early so nothing lands as a surprise change order.

## Frequently asked questions

**Are you part of Denver Water or the City and County of Denver?**

No. Denver Sewer and Water is a private, family owned and operated company that performs work for municipal clients as a contractor. We are not Denver Water or the City and County of Denver.

**Do you handle traffic control and permitted restoration?**

Yes. Traffic control, compaction, and surface restoration are planned into the scope on public-side work rather than treated as extras.

**Can you line a mainline instead of replacing it?**

Where the host pipe still has structural integrity, lining is frequently the lower-impact option. Inspection determines whether it is a candidate.

**Do you respond to public-side emergencies?**

Yes. We mobilize for urgent mainline failures. Call (720) 935-6221.

**Will you work as a subcontractor on a larger project?**

Yes. We regularly perform the underground sewer scope inside a broader civil or site project.
