Trenchless Sewer Repair Careers: Pipe Lining and Pipe Bursting Techs

Trenchless sewer repair is the repair or replacement of buried sewer lines without excavating an open trench along the run.

Instead of a backhoe following the pipe down the street, the work happens from access points — an existing cleanout, or pits dug at the ends of the section being worked on — and the two methods this page covers are cured-in-place pipe (CIPP) lining and pipe bursting.

It is one corner of the wider trade of underground plumbing work; this page is about the repair specialty and the crews that run it.

In the field, trenchless repair sits at the end of the diagnosis chain the rest of the trade builds.

A drain technician clears the blocked line, then sewer camera inspection shows whether the pipe itself is damaged — roots at a joint, a crack, a section that has settled — and locating equipment marks where.

When the finding is a damaged pipe rather than a blockage, the repair decision that follows is exactly the trenchless crew's territory: line it, burst it, or dig and replace a section.

One thing this page will not do is tell you the field is booming.

Trenchless market-growth figures were not confirmed by the research behind it, so there are no growth claims, market sizes or adoption percentages here.

What the page covers is the work itself: those methods, the crews, the NASSCO training names our research could verify, and the pay data that actually exists.

Pipe lining renews the old pipe from the inside.

A liner is positioned within the host pipe and cured in place — the "cured-in-place" in CIPP — leaving a new pipe inside the old one.

The host pipe stays in the ground; what runs through it afterward is the new liner pipe, and the failed pipe wall is no longer the surface carrying the flow.

Pipe bursting replaces the pipe instead of renewing it.

A bursting head is driven along the old line's path, breaking the existing pipe outward as a new pipe is pulled into place behind it.

The old pipe is not repaired; a new pipe takes over the run.

Where lining keeps the existing pipe as the frame, bursting ends the old pipe's life on purpose.

Both run from access points rather than an open trench, and which one fits a given line depends on what the inspection found and what surrounds the pipe — the condition of the host pipe, what lies above and beside it, and where access can be won.

Making that call well is the job, not a detail of it: the crew's work only goes right when the diagnosis underneath it did.

The comparison stays qualitative here on purpose.

Liner materials, cure processes, diameter and length limits, and equipment specifications were not confirmed by the sources we checked, so this page quotes none of them.

The manufacturer's documentation and the contractor who specifies the job are the authorities on what a given process can and cannot do on a given line.

The people on a trenchless job divide the work between them: equipment to set and run, pits and access points to establish, the site around them to control, and the pipe to prepare and inspect before and after the process runs.

The day is coordinated around a single installation rather than a queue of service calls, and each role on the crew feeds the same outcome: the new pipe in the ground, verified.

The training in this specialty that our research could put a name to comes from NASSCO, which runs the PACP, LACP and MACP classes for pipeline, lateral and manhole assessment, plus ITCP-CIPP inspector training for cured-in-place pipe.

The names map onto a system's parts and this specialty's material: PACP, LACP and MACP are the pipeline, lateral and manhole assessment classes, and ITCP-CIPP is named for cured-in-place pipe.

Beyond the named classes, your employer's training and the equipment manufacturer's manual are the authorities for the machines you will run.

Because bursting and pit work put people in the ground, excavation safety is part of the job.

OSHA says trench collapses — cave-ins — pose the greatest risk to workers' lives in trenching and excavation, and prescribes sloping or benching, shoring, or shielding such as trench boxes.

Under OSHA's excavation standard, every worker in an excavation must be protected from cave-ins by a protective system unless the excavation is entirely in stable rock or is under 5 feet deep with no indication of a potential cave-in as determined by a competent person (29 CFR 1926.652(a)(1)).

The wage tables we checked carry no trenchless line.

BLS publishes one combined occupation for the pipe trades — Plumbers, Pipefitters, and Steamfitters, SOC 47-2152 — and no separate wage or outlook for its individual members: not plumbers only, not pipefitters only, not sprinkler fitters only.

The tables we checked carry no drain-technician split of it either.

O*NET's sample of reported job titles for the occupation includes Drain Technician, Pipefitter and Plumber; a trenchless-specific title is not in the sample we checked, and nothing we checked says which occupation trenchless crews are counted in.

So this page has no trenchless wage to quote, and will not invent one.

The one figure the tables do give is the combined occupation's median: $30.67 an hour, or $63,800 a year, in May 2025 (OEWS, released May 15, 2026).

It is the drain-technician and plumber benchmark — the occupation O*NET counts Drain Technician within — not a lining or bursting wage, and not the specialty's pay band.

What the specialty pays is set shop by shop, and our research found no verified figure for it; the way to find out is to compare postings that name the work against those that don't, and ask the shops that run crews what they pay.

Travel follows the project shape of the work.

A crew sets up on a line, runs the installation, restores the site and moves to the next one — different from a service van working one stoppage call after another across a day.

How far those sites sit from home, and how assignments, hours and expenses are handled, is an employer-by-employer question; the postings and the hiring manager are the honest sources, and this page has no verified per-diem or travel-pay figures to offer.

See the drain technician salary page for the full national and state tables behind the benchmark, and current drain technician jobs for what shops near you ask for.

The specialty sits on top of drain and pipe fundamentals — diagnosis, clearing, and the judgment to know when a line is blocked and when it is broken.

If you are coming in from zero trade experience, our how to become a drain technician guide covers the entry rungs, and the camera-and-locator side and the clearing side of drain work are the fundamentals the repair work leans on.

One caution belongs to the licensing layer, not the skill layer: this page does not say who may legally perform sewer repair work where you live.

Confirm that with your state plumbing board or, where licensing is local, your city or county before you plan years around a job.

Our guide to whether drain work needs a plumbing license covers how the drain side is regulated.
