The lining process, step by step
Camera inspection
A camera runs through the lateral from a cleanout or fixture, showing cracks, roots, offsets and low spots.
Cleaning the pipe
Roots, scale and debris are cut or jetted out, because a liner will not bond to a dirty wall.
Liner preparation
A flexible tube soaked in resin is sized to the pipe and prepared for insertion.
Insertion and cure
The liner is pulled or inverted into place, pressed to the wall and cured with heat, light or time.
Reinstating and re-camera
Connections are reopened, then a second camera pass confirms the new pipe is smooth and open.
The steps are the same idea whether the job is short or long, but cleaning is where many jobs are won or lost. A thin liner on top of heavy scale leaves wrinkles that catch paper later.
This post is about the underground lateral to the street, not the vertical cast iron stack inside your walls. Those are separate repairs with different tools.
When lining will not work
| What the camera shows | Can it be lined? | Why |
|---|---|---|
| Cracks, roots, rough interior | Often yes | The pipe holds its shape for the liner to follow |
| Light joint separation | Often yes | The liner bridges small gaps |
| Collapsed pipe | Usually no | The liner cannot pass through a closed section |
| Large offset or dropped joint | Usually no | The liner cannot turn the step or hold flow |
| Belly holding standing water | Depends | Lining follows the dip, so the low spot remains |
| Sharp bend or missing section | Usually no | Excavation may be needed to correct the line |
Think your lateral may be failing?
Repeated backups, a gurgling floor drain or a sewage smell outside are worth a camera look. Call the 24/7 line to start.
Who owns what: house, lateral and street
The part of the sewer inside your property line is typically the homeowner's, while the public main under the street belongs to the system. Exactly where one stops and the other starts depends on local rules and records, so ask the Pennsauken Sewerage Authority before you assume.
In Pennsauken, the Authority collects sewage and the Camden County Municipal Utilities Authority treats it. Knowing which side a break falls on decides who pays and who repairs, so get an answer in writing if you can.
Pennsauken permits and approvals for sewer work
The township code lists the Pennsauken Sewerage Authority among the approvals that permits can depend on. Plumbing permits are issued by the Construction Code Department, 2400 Merchantville Ave, 856-665-1000.
What this means for you: before a sewer lining job, ask the Construction Code Department whether your specific repair counts as ordinary repair, and ask the Authority about any connection approval. We do not decide that for you from memory. CCMUA also closed a large loan to separate combined and stormwater sewers in Pennsauken, but that program does not change who owns your lateral.

Signs the lateral may be failing
Backups that return
A line cleared by a plumber that clogs again within weeks.
Gurgling in several drains
Air pushed back through traps as water struggles to move.
Wet or sunken spots outside
A lawn patch that stays soggy or sinks over the line path.
Root intrusion history
Mature trees near the line often send roots into joints.
Homes in Pennsauken with a median build year near 1964 often have laterals from that era, with older materials and joints that can separate over decades. That is a general pattern, not a claim about your house, which is why a camera inspection comes first.
Our sewer inspection service records that footage so you can see the same pipe we see.
Before the lining crew arrives
A little preparation keeps the day on track.
- Find your cleanout and clear access to it
- Limit water use during the work window
- Move vehicles from the area near the cleanout or driveway
- Ask for the camera footage before and after
- Ask who handles the permit and inspection
- If sewage is on the floor, avoid contact and keep children and pets away
What affects the price of lining
Lining cost depends on the pipe and the site, not on a flat formula.
We give a price by phone after an initial triage and confirm it after the camera, before work starts. If lining will not suit your pipe, we tell you plainly.
Standards and rules behind this advice
Cured-in-place lining is commonly specified to ASTM F1216 or ASTM F1743, and the New Jersey Uniform Construction Code governs permits.
Lining questions homeowners ask
No. Lining creates a new pipe inside the old one, while replacement removes and replaces the old pipe by trench or other methods. Lining often disturbs less ground, but it needs a pipe that is still in position. The camera decides, and our Cinnaminson plumber page shows how we serve that side of the county line.
Ask the Pennsauken Sewerage Authority about ownership and connection approvals, and the township Construction Code Department about permits. We can describe what we found on camera, but those offices set the rules.
A sealed liner leaves fewer gaps for roots to enter, but roots can still push at joints or the connection to the main. If trees are near the line, ask us how the ends and tie-ins are sealed.
A collapsed section usually cannot be lined through, so a spot repair or replacement is considered. We confirm that on camera before recommending anything. Our Collingswood plumber page describes similar jobs in nearby older neighborhoods.
The public main belongs to the collection system, not the homeowner. Within Pennsauken, that system is the Pennsauken Sewerage Authority for collection and CCMUA for treatment. Ask the Authority where your lateral connects before you plan a repair.
