If you need sewer line repair in Detroit, you're likely dealing with a backup that keeps coming back, roots in the line, or a camera report that found a break. We handle sewer line repair, replacement and camera inspection. Call (313) 474-7729 to talk it through, or describe your problem in the form.
Below: who's responsible for which section of pipe in Detroit, how sewer problems are diagnosed, the main repair options, and the city programs worth checking before you pay for anything.
Who owns the sewer line in Detroit?
This matters before anything else. According to the City of Detroit, the homeowner is responsible for the private sewer lateral: the pipe from where it leaves the house, usually under the basement floor, to where it connects to the city's collection sewer, often in the alley or a city easement. DWSD owns and maintains the public collection system. So if the problem is between your foundation and that connection, the repair is generally yours.
The city has announced an Alley Sewer Repair Program aimed at repairing private residential connections in the right-of-way. The city's program page describes it as covering the connection point, not the private line between the house and that connection. If your lateral runs to an alley, check the program page before you schedule work.
Why Detroit sewer laterals fail
With a median year built of 1947 and 78% of homes built before 1960 (ACS 2020–2024), most Detroit houses were connected to the sewer with vitrified clay pipe or, in some cases, cast iron. The common failure points:
| Problem | What causes it | Usual fix |
|---|---|---|
| Root intrusion | Roots enter clay pipe at the joints, which come every few feet | Root cutting, then repair or lining if roots return quickly |
| Offset or separated joints | Soil movement and freeze-thaw over decades | Spot repair of the section; sometimes full replacement |
| Belly (sag) | Settled soil under the pipe; water and solids collect in the low spot | Excavating and re-bedding or replacing that run |
| Cracked or collapsed pipe | Age, roots, heavy loads, old repairs | Replacement of the damaged section or whole lateral |
| Failed cast iron under the floor | Internal corrosion | Replacing the under-slab section |
Sewer line repair in Detroit, step by step
- Clear the line. If you have a backup, the first job is getting it flowing again, usually with a cable machine from the main cleanout.
- Camera inspection. A camera run down the lateral shows the pipe material, roots, offsets, bellies and breaks, and roughly where they are. Locating equipment can mark the depth and position at the surface.
- Choose the repair. A single bad joint near the house might be a spot repair. Multiple breaks or a collapsed section usually point to replacing the run. Trenchless lining or bursting is possible on some laterals; whether it suits yours depends on the pipe's condition and layout.
- Permit and inspection. Replacing sewer pipe in Detroit requires a permit from the Buildings, Safety Engineering and Environmental Department (BSEED). The city's FAQ notes that permits for a building sewer may be issued to someone other than a licensed master plumber, so ask who will pull it.
- Restore and re-check. After the repair, a final camera run is the best record you can keep for your house.
Permits for sewer work in Detroit
BSEED handles plumbing permits through the city's Accela online portal. The city's trade permit page estimates about one day to issue a plumbing permit after the application is submitted, and inspections are scheduled through the portal or the Construction Division. The plumbing FAQ says inspections are generally performed within 48 hours of the request. Outside Detroit, every suburb has its own building department; each of our area pages links to the right one, for example Dearborn, Warren and Royal Oak.
Sewer backups: what to do first
If sewage is coming up into your basement, stop using water in the house, keep people and pets away from the water, and call. In Detroit, DWSD's customer service line is listed on the city's water and sewer emergencies page if you suspect the problem is in the public sewer, for example if neighbors are backing up at the same time. If you plan to file a damage claim with a city because you believe the public sewer caused the backup, Michigan's sewage backup law requires written notice within 45 days; the City of Southfield's notice, for example, spells out that deadline.
City programs worth checking
- Alley Sewer Repair Program (Detroit): repairs to private connections in the right-of-way; see the city's program page for eligibility.
- CDBG-DR Private Sewer Repair Program (Detroit): for eligible income-qualified homeowners in target neighborhoods affected by the June 2021 floods, including camera inspection and private lateral repair.
- Basement Backup Protection Program (Detroit): backwater valves and sump pumps in target neighborhoods; DWSD's page says it isn't taking new applications until Phase 2 is complete.

Pricing
We don't list prices. Sewer line repair ranges from a simple cleaning to full replacement, and depth, length, pipe material and what's above the pipe all change the job. A camera inspection on site shows what's actually wrong, and the price follows from that. Call (313) 474-7729 to talk it through.
Questions to ask before sewer work starts
- Can I see the camera footage, and where exactly is the problem relative to the house?
- Is a permit required, and who pulls it? (In Detroit, replacing sewer pipe requires a permit.)
- Is the problem on my private lateral or in the public sewer?
- Would regular cleaning keep the line working for now, or is the pipe itself broken, offset or sagging badly enough to need repair?
- Will the work disturb a driveway, sidewalk or alley, and who restores it?
Frequently asked questions
Am I responsible for my sewer line in Detroit?
Per the City of Detroit, the homeowner is responsible for the private lateral from the house to its connection with the city sewer, often in the alley. DWSD maintains the public system.
Do I need a permit to replace a sewer line in Detroit?
Yes. Sewer pipe replacement requires a BSEED plumbing permit, applied for through the city's Accela portal. Clearing a stoppage doesn't.
What does a sewer camera inspection show?
The pipe material, roots, cracks, offsets, sags and collapsed sections, and roughly where they are, so the repair can target the right spot.
Can my sewer line be replaced without digging up the yard?
Sometimes. Trenchless lining or bursting suits some laterals, depending on condition, layout and access. A camera inspection is the first step to finding out.
How fast do I have to file a claim if the city sewer backed up into my basement?
Michigan law requires written notice to the government agency within 45 days of when you discovered, or should have discovered, the backup.
Does Detroit help pay for sewer line repairs?
Some programs exist, with eligibility limits: the Alley Sewer Repair Program and the CDBG-DR Private Sewer Repair Program. Check the city's pages for current status.
