Sewer Line Replacement
Warren, MI & Macomb & Oakland County
Full sewer lateral replacement is the last resort — only recommended when Picote HD camera footage confirms the pipe is beyond repair or lining. When replacement is the right call, trenchless pipe bursting is Bison’s preferred method: minimal access pits, no yard excavation, and new HDPE pipe installed in one day.
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: $265/ft + insertion pits (pipe bursting) or $10,000–$25,000+ (open-trench). 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
Trenchless Pipe Bursting
$265/ft + insertion pits · One day typicalA 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.
Open-Trench Replacement
$10,000–$25,000+ · 2–4 days typicalFull 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.
The Sewer Line Replacement Process
-
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.
-
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.
-
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.
-
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.
-
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
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.
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.
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 | $265/ft + pits | 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. |

Ask Bison about financing options when you receive your camera inspection report and replacement quote.
A sewer line replacement recommendation without camera footage is a guess at best and an 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.

Frequently Asked Questions — Sewer Line Replacement
Replacement is indicated when camera inspection confirms: a fully collapsed pipe section where the camera cannot pass, widespread structural failure along most of the lateral’s length, a pipe diameter too compromised for a CIPP liner to restore adequate flow, multiple severe fracture points where lining cost approaches replacement cost, or a severely bellied section that lining cannot correct. Bison never recommends replacement without camera footage that specifically justifies it.
Pipe bursting is a trenchless replacement method where a bursting head — slightly larger than the existing pipe diameter — is pulled through the old pipe by a winch system. As the head advances, it fractures the old pipe outward into the surrounding soil while simultaneously pulling new HDPE pipe into the void left behind. Only two small access pits are required at each end of the lateral — no open trench along the pipe run, no yard excavation, and no landscaping disruption above the pipe path.
Trenchless pipe bursting runs $265/ft + insertion pits. Traditional open-trench replacement runs $10,000–$25,000+ depending on pipe depth, length, and site complexity. GreenSky financing (Ref: 81085618) is available for same-day approval. All pricing is upfront after camera inspection defines the scope and confirms replacement is warranted.
The sewer lateral — the pipe running from your home’s foundation to the municipal connection point — is entirely the homeowner’s financial responsibility. The municipal sewer main in the street is maintained by the city or county. Standard homeowner’s insurance policies do not cover sewer line replacement unless a specific service line endorsement has been added to the policy.
Trenchless pipe bursting for a typical residential lateral (50–80 feet) is completed in one day — two small access pits, bursting head pulled through, new HDPE pipe installed, pits backfilled. Traditional open-trench replacement typically takes 2–4 days depending on pipe depth and length — excavation, pipe removal, new pipe installation, backfill, and surface restoration. Both methods require a Michigan LARA licensed plumber to perform the connection work at the municipal access point.
