Sewer Pipe Lining in Louisiana
Louisiana sewer lines sit in soft, settling ground with a water table at the surface, under houses that are themselves sinking a fraction of an inch a year. This page covers what fails under New Orleans, Baton Rouge and the rest of the state, why subsidence is the problem behind most of the others, who owns the lateral, and how a line gets rebuilt from inside.

What is in the ground in Louisiana
The median Louisiana home dates from around 1980, but New Orleans, Baton Rouge's Garden District and Spanish Town, Shreveport's Highland and the river parishes carry houses and sewer pipe from the 1890s through the 1930s: vitrified clay tile with a bell-and-spigot joint every few feet, laid shallow in ground that has moved continuously ever since, and cast iron under raised houses and the first slab houses. The postwar suburbs that filled Jefferson Parish, Gentilly, New Orleans East, Baton Rouge's rings and the Lafayette and Lake Charles outskirts went up on slabs with cast iron branch drains beneath them and clay, concrete or Orangeburg laterals to the street. Cast iron in Louisiana's wet, often acidic soil and humid air corrodes quickly, and under a slab that is itself settling unevenly it also cracks and separates. Houses built since the mid-1970s have PVC laterals, which in Louisiana fail mostly by geometry: a slab settles, the lateral leaving it tilts, and a belly or a sheared joint follows.
Soil, water and weather
Subsidence is the Louisiana sewer story. South Louisiana sits on deltaic sediment, soft clay, peat and organic silt that compacts under its own weight and under anything built on it, and that dewaters and shrinks further wherever the water table is pumped down. New Orleans has sunk several feet in a century and parts of it are still going down at a measurable rate every year; Baton Rouge and the Lake Charles area are not far behind. Sewer laterals laid level sink with the ground, but not evenly, so they end up with bellies, reverse grade and sheared joints at the house connection where the slab and the yard settle at different rates. The water table is at or near the surface across the southern half of the state, which means any open joint takes in groundwater, any trench fills before it is dug, and inflow and infiltration overload the sewer systems after every rain. New Orleans's Sewerage and Water Board and the Jefferson Parish system have operated under federal consent decrees for that reason. There is no frost, and the heat and humidity speed corrosion. Live oak, cypress and willow roots fill any leaking joint. North Louisiana, around Shreveport and Monroe, is red clay and sand on firmer ground, with more conventional root and joint problems.
What shows up on Louisiana camera inspections
- Bellies, reverse grade and sheared joints from uneven subsidence across New Orleans, Jefferson Parish and Baton Rouge
- Cast iron under settling slabs corroded through and cracked at the foundation
- Groundwater at the surface infiltrating every open joint and flooding any trench before it is finished
- Live oak, cypress and willow roots in the joints of century-old clay laterals
- Orangeburg and concrete laterals under postwar subdivisions crushed or separated by settlement
- Inflow-and-infiltration enforcement by consent-decree utilities that reject leaking connections
Which trenchless method fits
The camera decides. A line that still holds its shape is a lining job; a line that has been crushed, has lost its slope or has collapsed is a replacement job; a single bad joint in an otherwise sound run is a spot repair. Here is what each one does and where it stops being the right tool.
Sewer Pipe Lining (CIPP)
A resin-saturated liner cured inside the old sewer becomes a jointless new pipe, installed from a cleanout or manhole with nothing dug up.
Best for: Root-filled clay joints, scaled cast iron under a slab, cracked concrete or Orangeburg that still holds its shape, and any line under hardscape, a building or a mature tree.
Pipe Bursting
A bursting head splits the old pipe underground and pulls a new fused polyethylene line in behind it, between two small pits.
Best for: Crushed, deformed or collapsed pipe, severe offsets, undersized lines that need a larger diameter, and Orangeburg that has gone oval.
Sectional Point Repair
A short liner, two to twelve feet long, cured over one defect, leaving the sound pipe on either side alone.
Best for: One cracked joint, one offset, one root intrusion or one leaking connection in an otherwise sound line.
Storm Drain Lining
Cured-in-place and spin-cast lining for corrugated metal, concrete and clay storm pipe, culverts and roof drains, without closing the road or the parking lot.
Best for: Corrugated metal pipe rusted through at the invert, concrete storm lines with open joints, roof drains and parking lot drainage under slabs.
Who owns the pipe, and who issues the permit
Across Louisiana the property owner owns and maintains the sewer lateral, often called the house connection or service line, from the foundation wall to the tap on the main, taking in the section in the right-of-way. The Sewerage and Water Board of New Orleans, Jefferson Parish Sewerage, the City-Parish of East Baton Rouge, Lafayette Utilities System and Shreveport's Water and Sewerage all treat the lateral as private up to the main, with their own standards for the connection and, in New Orleans, a specific permit process through the Department of Safety and Permits. A plumbing permit pulled by a Louisiana-licensed master plumber covers the private side; a pit in the right-of-way needs a right-of-way or street-cut permit from the parish or city; and Louisiana 811 must be notified before any excavation. Because so much Louisiana ground is saturated, lining from a cleanout avoids a dewatered trench and the permit for it, and the utilities generally accept a lined lateral provided they can see video of the connection.
Finding a lining contractor in Louisiana
Louisiana does not yet have a verified installer listed on this site, which is why the number on this page rings the national line. Call it or send the form with the property address and what the camera or the symptoms are showing, and we will locate a qualified trenchless contractor near you and make the introduction; there is no charge for that. If you are a Louisiana lining contractor with five or more years in business and a strong Google rating, the territory is open: apply to be listed.

Where lining is in demand across Louisiana
The pipe problems described above are concentrated in the older cities and the postwar suburbs around them. The communities below are the ones Louisiana property owners ask about most, and the same methods apply everywhere in between.
A straight answer about your Louisiana sewer line
In Louisiana the question is rarely whether a lateral is broken; it is whether it has moved too far to line. A clay line with roots at every joint but still holding grade is a lining job; a line that has sunk into a belly or sheared at the slab is not, however good the liner. The camera tells them apart and locates each defect from above with its depth. The recording is yours; the written scope names the method, the footage, the price and the reasons the alternatives were set aside.

How a job runs
Camera first. Always.
A sewer quote given without video is a guess, and guesses are how homeowners end up paying for a liner that was never going to fix the problem. Here's the sequence we follow on every job.
-
Step 1
Camera inspection, recorded
A self-leveling camera runs the full line from the cleanout, manhole or roof drain to the main. Every crack, offset, root mass, belly and connection is logged with its distance, and a locator marks each one on the surface with its depth. You get the recording.
-
Step 2
Cleaning to bare wall
A hydro jetter, with chain cutters or a descaler where cast iron or roots call for them, strips the pipe to its original surface. The camera goes through again afterward, because a cleaned pipe tells the truth about its condition in a way a dirty one cannot.
-
Step 3
A written scope, with the alternatives
The scope names the method, the footage and diameter involved, the price, the permits and inspections that apply, and the reasons the other methods were set aside. When the right answer is a dig, the scope says so.
-
Step 4
Permits and notifications
The installer pulls the plumbing permit, any right-of-way or sewer-authority permit, schedules the inspections the local authority requires and files the utility-locate ticket before anything is opened.
-
Step 5
The work, usually in a day
A residential liner typically cures in a few hours; bursting a lateral takes a day or two; a building or municipal reach is phased so no one loses their drains for more than a night. Branch lines are reinstated with a robotic cutter.
-
Step 6
Final video, with you watching
The camera goes back through the finished pipe. You see the new interior end to end, and the recording goes in your file along with the warranty and the permit sign-offs.
