Sewer Line Replacement Options in Tigard
Once diagnostics show that a sewer line has deteriorated beyond a dependable localized repair, Woodward Plumbing can evaluate the best replacement method for the property.
The appropriate approach depends on factors such as:
- Pipe condition
- Location and depth
- Sewer alignment
- Access points
- Nearby underground utilities
- Driveways, patios, landscaping, and other surface improvements
- Connections to the existing plumbing and public sewer
- Whether the existing route can support a trenchless replacement method
Two major approaches are trenchless replacement and traditional open excavation.
Trenchless Sewer Replacement With Pipe Bursting
Pipe bursting is a trenchless sewer replacement method that can install new piping through the general route of an existing damaged sewer.
Specialized equipment breaks or displaces the old pipe as new replacement pipe is pulled through.
Because the new pipe follows the existing underground route, pipe bursting can reduce the amount of continuous surface excavation compared with digging an open trench along the entire sewer line.
Potential advantages can include:
- Less continuous excavation
- Reduced disturbance to portions of landscaping
- Less disruption to some walkways or finished areas
- A new replacement pipe rather than continued reliance on deteriorated host piping
Trenchless does not mean no digging.
Access pits, connection work, excavation at certain locations, and other site preparation may still be required.
Pipe Bursting and Pipe Lining Are Different
This distinction is central to choosing the correct service.
| Method |
What Happens |
Primary Intent |
| CIPP pipe lining |
A structural liner is cured inside suitable existing pipe |
Repair / rehabilitation |
| Spot repair |
A limited damaged section is corrected |
Repair |
| Pipe bursting |
The old pipe is displaced while new pipe is installed |
Replacement |
| Open-trench replacement |
The existing sewer route is excavated and new piping installed |
Replacement |
A homeowner does not necessarily need full sewer replacement simply because trenchless technology is available.
CIPP can preserve and rehabilitate a suitable existing line. Pipe bursting installs new replacement piping.
That is why the condition of the existing sewer should determine the method.
When Is Pipe Bursting a Good Option?
Pipe bursting may deserve consideration when:
- A substantial portion of the existing sewer needs replacement
- The general sewer route can be reused
- Reducing continuous excavation would benefit the property
- The old pipe can be displaced using the proposed method
- Connection points and access allow the equipment to be used effectively
A site evaluation is still necessary.
Underground utilities, pipe configuration, bends, connections, soil conditions, access, and other project-specific factors can affect whether pipe bursting is appropriate.
When Is Traditional Excavation Better?
Open-trench sewer replacement remains important because some failures cannot be corrected by following the existing pipe route.
Excavation may be necessary when:
- The existing sewer has significant alignment problems
- Grade needs to be corrected
- A major low spot needs physical reconstruction
- The route needs to change
- A connection requires direct access
- A severely collapsed area prevents use of the proposed trenchless method
- Site conditions make conventional replacement more practical
The better method is the one that produces a reliable sewer system after the project is finished—not automatically the option involving the least visible excavation.
Our Sewer Line Replacement Process
Step 1: Diagnose the Sewer Problem
We start by understanding the history and symptoms.
Useful information can include:
- How frequently the sewer backs up
- Whether multiple fixtures are affected
- Previous drain cleaning or rooter work
- Known root problems
- Previous sewer repairs
- Any sudden change that could suggest external pipe damage
An active obstruction may need to be cleared before the pipe can be properly evaluated.
Step 2: Inspect and Locate the Damage
Video diagnostics help determine whether the problem involves one repairable section or broader structural deterioration.
The sewer route and damaged areas can then be evaluated alongside property access and surface conditions.
Step 3: Compare Repair and Replacement Options
Replacement should only move forward after the alternatives have been considered.
Possible recommendations can include:
- Cleaning when the pipe remains structurally sound
- Localized sewer repair
- CIPP rehabilitation for a suitable host pipe
- Pipe bursting for qualifying replacement projects
- Open excavation and replacement
This helps match the project scope to the actual condition of the sewer line.
Step 4: Complete the Replacement
The damaged sewer is replaced using the approved method.
New piping, connections, excavation, and access work depend on the project design.
Step 5: Verify the New Sewer System
After installation, the replacement system should be checked to confirm proper wastewater flow and completion of required connections or inspections.
The purpose of sewer replacement is not simply to eliminate today’s backup. It is to restore a dependable route for wastewater leaving the property.
How Much Does Sewer Line Replacement Cost in Tigard?
Sewer line replacement pricing depends heavily on the property and the work required underground.
Important cost factors include:
- Length of pipe being replaced: Replacing one substantial section differs from replacing the entire lateral.
- Pipe depth: Deeper sewers typically require additional excavation and safety considerations.
- Replacement method: Pipe bursting and open-trench installation involve different equipment and labor.
- Property access: Equipment access can affect project planning.
- Surface conditions: Landscaping, patios, sidewalks, driveways, and other improvements can influence the scope.
- Existing pipe condition: Severe collapse or deformation can affect available methods.
- Grade and alignment: Problems with sewer slope or route may require physical reconstruction.
- Underground utilities: Water, gas, electrical, communications, and other utility lines must be considered.
- Connection work: Existing building drains and public sewer connections influence project design.
- Permits and inspections: Local requirements depend on where and how the work is completed.
An upfront evaluation gives homeowners a much more useful basis for pricing than estimating replacement solely from the fact that a sewer has backed up.

Sewer Replacement Permits in Tigard
A substantial sewer-line replacement can involve multiple local requirements.
The City of Tigard’s Engineering Division identifies the installation and repair of sewer service lines among activities that may require an engineering permit. Work within the public right-of-way can also trigger additional review and inspection requirements.
Tigard’s Permit Center separately handles plumbing trade permits.
The exact approvals depend on the project location, excavation area, connection points, and replacement method.
Woodward can account for applicable plumbing codes, permits, inspections, and utility coordination while planning the sewer project.
Protecting Landscaping and Finished Surfaces
One reason homeowners ask about trenchless sewer replacement is concern about property disruption.
A sewer lateral may travel beneath or near:
- Lawns
- Trees and landscaping
- Walkways
- Patios
- Driveways
- Fencing
- Other improvements
Pipe bursting can reduce continuous excavation on suitable projects, but no contractor should promise that a sewer replacement will involve absolutely no digging.
Access points, utility conflicts, damaged connections, or grade correction can still require excavation.
Understanding the sewer route before work begins makes it easier to compare the potential property impact of each replacement method.

Frequently Asked Questions About Sewer Line Replacement in Tigard
How do I know whether my sewer line needs to be replaced?
Replacement becomes more likely when camera diagnostics show widespread structural damage, multiple failing sections, significant deformation, severe collapse, repeated root intrusion, or deterioration that makes continued repairs unreliable.
A blockage or one localized defect does not automatically require full sewer replacement.
Why does my sewer line keep backing up after it has been cleaned?
Repeated backups can occur when cleaning restores flow without correcting the condition that caused the blockage.
Possible underlying problems include cracks, root intrusion, separated joints, offsets, low areas, deterioration, or partial collapse.
Recurring problems are a reason to evaluate the pipe rather than repeatedly assuming the issue is another ordinary clog.
Can tree roots mean I need a new sewer line?
Not always.
Roots may be removable without replacing the sewer. A localized entry point may also be repairable.
Replacement becomes more likely when root intrusion occurs through multiple failing areas, the pipe has been crushed or badly damaged, or roots continually return because the sewer is deteriorating throughout.
Can a sewer line be repaired instead of replaced?
Yes.
Localized cracks, failed joints, and other limited defects may be suitable for spot repair. Some longer damaged sections can qualify for CIPP pipe lining when the existing host pipe remains suitable.
The upcoming Tigard sewer line repair service focuses on preserving repairable piping rather than replacing an entire line unnecessarily.
What is trenchless sewer line replacement?
Trenchless replacement uses methods that can install new underground sewer piping while reducing continuous open excavation.
Pipe bursting is one example. The existing pipe is broken or displaced as a new replacement pipe is pulled through its general route.
Some excavation for access and connections may still be necessary.
Is pipe lining the same as pipe bursting?
No.
CIPP pipe lining rehabilitates a suitable existing sewer by installing a structural liner within the host pipe.
Pipe bursting replaces the old sewer with new piping.
That makes pipe lining primarily a repair or rehabilitation method and pipe bursting a replacement method.
Can pipe bursting replace a collapsed sewer line?
It depends on the specific condition and layout.
Severe collapse, alignment problems, connection conditions, underground utilities, access, and other factors can affect whether pipe bursting is technically practical.
Some collapsed sewer lines require conventional excavation.
Is trenchless sewer replacement completely excavation-free?
No.
Trenchless generally means less continuous excavation, not zero digging.
Access pits, connection points, utility conflicts, or other project conditions can still require excavation.
When is open-trench sewer replacement better?
Traditional excavation may provide the better solution when the sewer route needs to change, grade must be corrected, a severe low spot exists, direct access to connections is required, or pipe conditions prevent a reliable trenchless installation.
What happens if my sewer line has improper slope?
A significant grade problem may allow wastewater and solids to collect rather than flow consistently toward the public sewer.
Pipe lining follows the existing route and cannot automatically correct an improperly graded sewer.
Replacement involving physical reconstruction may be needed when slope itself is the underlying problem.
Can a utility bore damage a sewer line in Tigard?
Yes. The City of Tigard specifically identifies underground utility boring as a potential source of sewer-lateral damage.
The City advises residents to contact Public Works when a blockage cannot be cleared and a plumber suspects that a utility bore has penetrated the lateral.
Should a sewer line be cleaned before camera inspection?
Cleaning can make an inspection more useful when debris or standing wastewater obscures the pipe.
Tigard’s sanitary-sewer guidance specifically recommends cleaning a lateral before video inspection to help provide a clearer view of its actual condition.
How long does sewer line replacement take?
Project duration varies by method, sewer length, depth, access, permits, utility coordination, excavation requirements, and connection work.
A straightforward trenchless project and a sewer requiring extensive excavation and grade correction can have very different timelines.
How much does sewer line replacement cost in Tigard?
Cost depends on the length and depth of the sewer, replacement method, access, surface conditions, existing pipe damage, grade, nearby utilities, connection work, permits, and inspections.
A diagnosis and site evaluation are necessary before the scope can be priced accurately.
Does sewer line replacement require a permit in Tigard?
It can.
Tigard identifies sewer service-line installation and repair among work that may require engineering permits, particularly where public infrastructure or the right-of-way is affected. Plumbing permit requirements can also apply depending on project scope.
Can sewer replacement damage my driveway or landscaping?
Some disruption may be unavoidable depending on the sewer route.
Trenchless pipe bursting can reduce continuous excavation for suitable properties, while traditional replacement may require opening portions of the yard, driveway, walkway, or other surfaces to access and reconstruct the sewer.
Do you offer financing for sewer replacement?
Financing options are available for qualifying plumbing projects.
Sewer replacement can be a significant investment, so eligible homeowners can review Woodward’s financing options while evaluating the recommended work.
Do you provide sewer line replacement for commercial properties?
Woodward can evaluate applicable commercial sewer replacement needs in Tigard.
Commercial systems can involve different wastewater volumes, pipe sizes, access conditions, and operational considerations, so the replacement plan depends on the specific property.
Schedule Sewer Line Replacement in Tigard, OR
Repeated sewer backups do not automatically mean you need a new sewer line. The decision should be based on what is actually happening underground.
Woodward Plumbing evaluates sewer damage before comparing cleaning, repair, trenchless rehabilitation, pipe bursting, and traditional replacement options.
For lines with widespread deterioration, severe structural damage, repeated failures, or conditions that can no longer be repaired reliably, sewer replacement can provide a new path forward.
