Sewer Camera Inspection in St. Louis City
In St. Louis City, MSD maintains the public sewer main, and the lateral from your building to it is private property, even where it runs under the street or alley. A camera inspection records what is inside that line on video, with written findings. It is your own evidence, separate from the City’s lateral repair program, which asks for its own plumber’s video and excludes clogs and roots.
Your lateral runs to the MSD main, even under the street
MSD says it maintains the public sewer main, and that the lateral connecting your building to that main, including its connection, is private property and normally the owner’s to maintain and repair, even where it runs under the street or alley. The City says the same of the entire lateral from a home to the MSD main.
That is why the camera matters here. A line that is yours all the way to the main is a line you need evidence about. The footage records what is visible in the section the camera reaches, and you can ask that the written findings note where along the line each condition was seen. It does not establish where the connection to the main is, or who is responsible at a given point.
What the City’s repair program asks for, and where a camera fits
The City’s Sewer Lateral Repair Program is aimed at severe damage under the public right-of-way that causes a cave-in or a backup into the home, for residential properties of six or fewer units with fully paid real-estate taxes. The City says it does not cover clearing clogs or tree roots anywhere on the lateral, or breaks under private property.
The City’s page says to hire a licensed City plumber to inspect the line and send the plumber’s statement and video to the Street Department, and the City decides eligibility. An independent camera inspection does not replace that step. It gives you your own recorded evidence, which can help you tell a clog or root problem the program does not cover from damage worth raising with the Street Division. The program page is dated 2014, so confirm current terms and funding with the Street Division.
Older City housing, combined sewers, and what only a camera shows
About 58 percent of St. Louis City’s housing units were built in 1939 or earlier, according to American Community Survey 2019-2023 estimates as republished by Point2Homes (our location page notes the primary Census table check is pending). Older laterals were commonly vitrified clay, which wears at the joints and lets roots in, or cast iron, which corrodes and scales on the inside. Those are general industry timelines, not a statement about any one home, and many laterals have been repaired or replaced since.
- Roots, deposits and obstructions visible inside the pipe
- Cracks, and offset or separated joints
- Visible corrosion on the inside of the pipe, and standing water
MSD says most of the City is served by combined sewers that can be overwhelmed in intense rain, which can cause wet-weather basement backups in affected areas. That is a system-level fact, not a finding about your lateral. A camera also cannot see under water, so in a line that is blocked and not draining, cleaning may need to come first.
Who to call first, and what the camera does not decide
If sewage is backing up through a floor drain, you smell sewage outside, or you see an overflow or a missing manhole cover, MSD asks you to report it right away at (314) 768-6260 (MSD’s number, not ours). MSD investigates whether the cause is the public sewer or your lateral. If MSD or a plumber points to your lateral, or you want proof of its condition, a camera records it.
The City says replacing a lateral requires a plumbing permit and inspection, issued to City-certified licensed plumbing contractors. A camera inspection does not tell you which approvals apply, and a finding is a visible observation, not a repair recommendation. The Sewer Pros inspects and documents. It does not perform repairs or replacements.
When to call
Recurring clogs
Clogs that keep returning may warrant a look at the accessible line instead of clearing each one as a separate event.
Slow-draining sinks, tubs, or toilets
Slow drains can have several causes. A camera can document what is visible in the accessible line.
After a sewage backup
After a backup, a camera may help document what is visible. If the line is blocked and not draining, cleaning may need to come first.
A City program asks for inspection video
St. Louis City’s lateral repair program requires video from an inspection and excludes clearing clogs and roots. Confirm the program’s current requirements with the City before relying on any inspection.

Sewer Inspection, Diagnostics & Cleaning Services
The Sewer Pros provides sewer camera inspections, sewer diagnostics, sewer cleaning, hydro jetting, sewer line locating, and drain cleaning for residential properties. We document the conditions we observe so property owners, homebuyers, and property managers can understand the issue and consider appropriate next steps.
Sewer Camera Inspection
A camera inspection of the accessible sewer line, documenting what is visible. It can help identify observed conditions and support an informed next-step decision.
Sewer Cleaning
Remove buildup and obstructions from sewer lines when cleaning is appropriate. A camera inspection can help document line conditions before or after cleaning.
Hydro Jetting
Use high-pressure water to clean eligible sewer lines. Whether jetting is appropriate depends on the line’s observed condition.
Sewer Cleaning & Camera Inspection
Combine cleaning with visual documentation of the line. See what was observed and whether cleaning changed the conditions visible by camera.
Sewer Line Locating
Help identify the route of an accessible sewer line and locate a specific area when conditions allow. Useful when planning further evaluation or work.
Drain Cleaning
Address buildup or blockages in drains serving sinks, tubs, and other fixtures. The service focuses on the affected drain and the reported symptoms.
Pre-Purchase Sewer Inspection
Get a visual assessment of accessible portions of the sewer line before buying a property. The findings can help inform your due diligence.
Recurring Sewer Backup Diagnosis
Investigate recurring backups and document conditions observed during the inspection. Findings can help clarify what may be contributing to the problem.
Preventative Sewer Maintenance
Arrange sewer inspection or cleaning based on the line’s condition and service needs. Recommendations should be guided by observed evidence.
How we work
The inspection is the product
Finding out what is happening in the line is the job, not a step toward selling a repair.
You see the evidence
Conditions found in the line are documented so you can look at them yourself.
Sewer and drain specialists
Sewer inspection, diagnostics, locating, and cleaning, rather than general plumbing.
The next step stays your decision
If the line needs work beyond cleaning, you decide what to do about it and who does it.

Common questions about Sewer Camera Inspection in St. Louis City
In St. Louis City
Who is responsible for a sewer blockage on private property in St. Louis?
MSD states that property owners are responsible for maintaining and repairing their lateral line. MSD identifies a blockage in the private lateral as a common cause of sewer backup and says private lateral issues are not MSD issues.
Does MSD fix the sewer line between my house and the street?
No. MSD maintains the public main. The lateral from your building to the main, including its connection, is private property and is normally the owner’s responsibility. MSD repairs the public sewer if it caused a backup.
Can a sewer line be cleaned instead of replaced?
Often, when the problem is roots, grease or debris and the pipe is structurally sound. A camera inspection shows which situation you have, so cleaning or hydro jetting is chosen on evidence rather than assumption.
Should I inspect the sewer before buying a house in St. Louis City?
It is a smart step for most purchases, especially older homes. The lateral becomes your responsibility at closing, and an inspection documents its condition first.
What are possible signs of a blocked or damaged private lateral?
MSD lists slow drains, water pooling around basement floor drains, sewage odor inside or outside the building, wastewater leaking from a cleanout, and wet ground in the yard. A camera inspection can document what is actually happening inside the line.
Why can heavy rain contribute to sewer backups in St. Louis City?
MSD says the City is largely served by combined sewers, which carry stormwater and wastewater in the same public pipes. Excess stormwater can overload the system and contribute to basement backups. This is a system-level explanation, not a finding about any one property.
Does the City repair every private lateral under a street or alley?
No. The City states the entire lateral from a home to the MSD main is private property. Its Sewer Lateral Repair Program may assist eligible residential properties of six or fewer units when qualifying severe damage is beneath the public right-of-way, but it does not cover every lateral condition, and the City states it does not cover clearing clogs or tree roots anywhere on the lateral.
How does a St. Louis City owner apply for the Sewer Lateral Repair Program?
The City’s program page says to report a cave-in in the right-of-way through its street problem service request page, hire a licensed City plumber to inspect the line, and send the plumber’s statement and video to the Street Department by mail, email or fax. The program covers only qualifying damage under the public right-of-way, and the City decides eligibility.
Do you repair or replace sewer lines?
No. We inspect, locate, diagnose and clean. That independence is the point: our recommendations are not built around selling a repair.

Can a sewer camera tell how deep the pipe is?
No. A camera shows what is inside the pipe, not how deep it sits or where it runs in your yard. It also does not measure pipe slope. Sewer line locating can estimate a position from the surface, and a locate is an estimate, not a survey.
