Quick Answer

Sewer line replacement is recommended only when Picote HD camera footage confirms the lateral is beyond repair — full collapse, widespread structural failure, or a pipe diameter too compromised for CIPP lining to restore adequate flow. Trenchless pipe bursting is Bison’s preferred replacement method: the bursting head fractures the old pipe outward while pulling new HDPE pipe into place — two access pits, no open trench, completed in one day. Cost: $8,000–$25,000 depending on method and lateral length. GreenSky financing available (Ref: 81085618). Part of Bison’s Drain & Sewer Services.

The decision to replace a sewer lateral is significant — financially and logistically. It is also, when the camera footage justifies it, the correct decision that ends years of recurring backups, repeated cleaning expenses, and progressively worsening pipe deterioration. Bison’s position is straightforward: we do not recommend replacement without footage that specifically confirms the pipe cannot be rehabilitated. And when replacement is warranted, we present the least invasive viable method first.

For most Macomb and Oakland County homeowners, that means trenchless pipe bursting — the method that installs new pipe without excavating the yard above the lateral. For pipes where bursting is not viable — where full collapse has created no continuous path for the bursting head — traditional open-trench replacement is the fallback. Both methods result in a new HDPE sewer lateral with a 50+ year design life, properly permitted, and installed by Michigan LARA licensed plumbers.

When Does a Sewer Line Need to Be Replaced?

Replacement is indicated by camera footage — not by the severity of the symptoms alone. These are the conditions that specifically require replacement rather than repair:

🚫

Full Pipe Collapse

The camera cannot pass the blocked section — the pipe has lost structural integrity and the channel no longer exists. CIPP lining cannot be inserted into a collapsed section. Pipe bursting (if a partial path remains) or open-trench replacement is required.

🌿

Root-Consumed Pipe

Root mass has filled the pipe at multiple locations along the full lateral length, combined with structural wall damage at those entry points. When the density of root fracture locations makes lining cost approach or exceed replacement cost, replacement is the more economical long-term solution.

🔽

Severe Belly with No Flow Path

A pipe belly (low sag section) so severe that wastewater pools permanently and flow cannot be restored by lining. CIPP lining follows the existing pipe profile — it cannot lift a bellied section. Excavation to realign the grade is the only viable fix.

👥

Diameter Too Compromised for Lining

Cast-iron pipe with extreme interior corrosion, or clay pipe with severe joint offset, can reduce the effective pipe diameter to the point where inserting a CIPP liner would further restrict flow below functional thresholds. Camera footage confirms the available diameter before lining is ruled out.

🔌

Multiple Collapse Points

Two or more distinct collapsed or severely fractured sections spaced along the lateral make full lining more cost-effective than multiple spot repairs — or make trenchless replacement the clear economic choice when compared to staged repair over multiple service visits.

📈

End-of-Life Lateral — Replacement + Upgrade

For pre-1960 homes where the clay lateral is approaching 70–80 years old, showing widespread joint deterioration, and has no single catastrophic failure point — proactive replacement before emergency failure can be the most cost-effective choice when total repair scope exceeds 60–70% of replacement cost.

Trenchless Pipe Bursting vs. Traditional Open-Trench Replacement

⭐ Preferred Method — Bison’s First Choice

Trenchless Pipe Bursting

$8,000–$18,000 · One day typical

A bursting head — slightly larger than the old pipe diameter — is pulled through the lateral by a winch. It fractures the old pipe outward into surrounding soil while simultaneously pulling new HDPE pipe into the void. Two small access pits at each end of the lateral are the only surface disruption.

ExcavationTwo small access pits only — no open trench
TimelineTypically completed in one day
LandscapingNo yard, driveway, or garden disruption above the pipe path
New PipeHDPE — 50+ year design life, seamless, root-resistant
Viable WhenOld pipe retains some continuous path for the bursting head

Fallback Method — When Trenchless Is Not Viable

Open-Trench Replacement

$10,000–$25,000+ · 2–4 days typical

Full excavation of the lateral from foundation to municipal connection — old pipe removed, new pipe installed, trench backfilled, and surface restored. Required when the old pipe is too collapsed or fragmented for the bursting head to navigate.

ExcavationOpen trench along full pipe run — typically 4–8 ft wide
Timeline2–4 days depending on depth and length
LandscapingRestoration required — lawn, hardscape, or driveway above trench
New PipePVC or HDPE — properly bedded and graded
Required WhenFull pipe collapse with no continuous path; severe belly requiring grade correction
Quoted after camera confirms trenchless is not viable

The Sewer Line Replacement Process

1

Camera Inspection — Confirm Replacement Is Warranted

The Picote Solutions HD camera runs the full lateral — documenting the damage and confirming that the pipe cannot be rehabilitated by CIPP lining, pipe patching, or spot repair. Bison will not quote replacement without this footage. If lining is viable, lining is quoted first.

2

Method Determination — Trenchless or Open-Trench

Camera footage and site assessment determine whether pipe bursting is viable. If the collapsed pipe retains any continuous path for the bursting head, trenchless is presented first. If not — multiple collapse points, no navigable path — open-trench replacement is the appropriate recommendation.

3

Permit Pulled — Michigan LARA Licensed Work

Sewer line replacement requires a permit from the relevant municipality — City of Warren, City of Royal Oak, City of Troy, etc. — and must be performed by a Michigan LARA licensed plumber. Bison handles permit acquisition before any excavation or trenchless work begins. The connection work at the municipal access point requires licensed plumber sign-off in all Michigan jurisdictions.

4

Replacement Executed — Trenchless Bursting or Excavation

For pipe bursting: access pits excavated at each end, bursting head and new HDPE pipe prepared, winch system set, bursting head pulled through, new pipe seated, pits backfilled. For open-trench: trench excavated to pipe depth along full lateral run, old pipe removed, new pipe bedded and graded, trench backfilled in lifts, surface restored.

5

Post-Installation Camera Verification & Permit Sign-Off

After installation, camera inspection confirms correct pipe seating, grade, and connection integrity. Municipal inspection sign-off closes the permit. Homeowner receives documentation confirming the new lateral is installed to code and inspected.

Who Is Responsible for the Sewer Line?

One of the most common questions homeowners ask before a replacement project — and one that directly affects the financial conversation:

🏠 Homeowner vs. City — Sewer Responsibility Breakdown

🔴 Your Responsibility

Private Sewer Lateral

The pipe from your home’s foundation to the municipal connection point — entirely the homeowner’s financial responsibility. This is the section Bison replaces. Typically 50–100 feet depending on lot depth and street proximity.

🔵 Shared / Varies

Connection Point

The wye connection where your private lateral meets the public sewer main. Typically located at the property line or in the public right-of-way. Jurisdiction varies by municipality — Bison confirms the connection scope with the local municipality before quoting.

🟢 City / County Responsibility

Public Sewer Main

The main sewer pipe in the street — maintained by the City or Macomb/Oakland County Public Works. Problems in the main (surcharge events, main blockages) are reported to the relevant public works department — not Bison’s scope.

Insurance note: Standard homeowner’s insurance policies do not cover sewer lateral replacement unless a specific service line endorsement has been added to the policy. Some insurers offer sewer backup riders that cover damage from backups but not the lateral replacement itself. Contact your provider before assuming coverage applies.

Cost Ranges — Sewer Line Replacement

Service Cost Range Notes
Camera Diagnostic Inspection $150–$400 Required before any replacement is quoted. Applied toward replacement cost if Bison performs the work.
Trenchless Pipe Bursting $8,000–$18,000 Typical 50–80 ft residential lateral. Two access pits. Completed in one day. New HDPE pipe.
Traditional Open-Trench Replacement $10,000–$25,000+ Full lateral excavation. 2–4 days. Surface restoration included in scope. Permit required.
Deep Lateral Replacement (6+ ft depth) $15,000–$35,000+ Deeper pipe depth increases excavation scope and shoring requirements. Camera footage confirms depth at damage locations.
Permit (varies by municipality) $200–$800 Required by City of Warren, Royal Oak, Troy, and all Macomb/Oakland County municipalities for sewer lateral replacement work.

⚠ Never Accept a Replacement Quote Without Camera Footage

A sewer line replacement recommendation without camera footage is a guess at best and a upsell at worst. The footage defines whether replacement is warranted, which method is viable, and the exact scope of work. If a contractor recommends sewer line replacement without first running a camera inspection, ask to see the footage that justifies it — or call Bison for a second opinion camera inspection.
