When sewer lines fail, there are usually two ways to deal with them. The pipe can be dug up and replaced, or it can be repaired from the inside. These are often referred to as trenched sewer repair and trenchless sewer repair.
Depending on the situation, one method might be a better option than the other. Each one is used for different types of damage. The right option depends on the condition of the pipe and what is found during inspection.
Scott Hale Plumbing, Drains, Heating & Air works with homeowners in Salt Lake City to explain these options before any work begins.
Traditional Method
What Is It?
Trenched sewer repair involves digging down to the sewer line. The damaged pipe is fully exposed so it can be repaired or replaced.
This method has been used for many years. It allows direct access to the sewer line and makes it possible to remove sections of pipe that are no longer usable.
When It’s Used
Trenched repair is used when the sewer line is badly damaged.
This usually includes:
- Pipes that have collapsed
- Pipes that are broken or crushed
- Sewer lines that have shifted out of place
- Sections of pipe that can’t support internal repair
In these cases, the pipe needs to be accessed directly to fix the problem correctly.
Why It Might Be the Better Option in Some Cases
While trenching is more disruptive, it can be the most reliable option when the pipe is in poor condition. Full access makes it possible to remove damaged sections and replace them entirely.
If trenchless sewer repair isn’t possible, trenching allows the sewer line to be repaired without leaving weakened sections behind.
Trenchless Sewer Repair
What Is It?
Trenchless sewer repair fixes the pipe from the inside instead of removing it. A lining or repair material is installed inside the existing sewer line.
This method relies on the pipe being intact enough to hold the repair material. The pipe stays in place, and digging is limited to small access points.
When It’s Used
Trenchless sewer repair is used when the pipe has internal damage but hasn’t collapsed.
Common situations include:
- Cracks inside the pipe
- Root intrusion
- Deterioration that affects flow
- Repeated backups caused by internal damage
Because there is no full excavation, this method often limits surface disruption.
Why It Might Be the Better Option in Some Cases
Many homeowners prefer trenchless sewer repair because it avoids tearing up the yard or driveway. Landscaping, concrete, and walkways are often left in place.
Trenchless repair can also reduce how long the sewer is out of service. When the pipe condition allows for it, this approach can solve the problem with less cleanup afterward.
How to Decide Between the Two
Choosing between trenched and trenchless sewer repair starts with inspection. A camera inspection shows the condition of the pipe and where the damage is located.
Things that affect the decision include:
- The extent of the damage
- The age and material of the pipe
- Pipe collapse or shifting
- The location of the sewer line
In most cases, the inspection determines which options are available.
What Your Technician Recommends Matters
Sewer repair recommendations are based on what will fix the problem properly.
If trenchless sewer repair is recommended, it means the pipe can support an internal repair. If trenching is recommended, it usually means the damage is too severe to repair from the inside.
Understanding this helps homeowners know why one method is suggested over the other.

FAQs
Does the type of damage affect which repair method is used?
Yes. Internal damage may allow for trenchless repair, while collapsed or broken pipes often require trenching.
Does the location of the sewer line matter?
Yes. Sewer lines under driveways or walkways may be good candidates for trenchless repair if the pipe condition allows.
Is trenchless sewer repair always an option?
No. The pipe must be intact enough to support a lining.
How do I know which option is right for my home?
A camera inspection and professional evaluation determine the correct repair approach.
