Industrial Pipe Rehabilitation
Industrial trenchless pipe repair for plants and warehouses in Burbank
Industrial drainage in Burbank is bigger, deeper and busier than anything under a house, and it sits beneath slabs, rail spurs and yards that cannot be opened without stopping work. This page covers how lining and bursting are applied to industrial sanitary, process and storm lines, and what the plant engineer needs to have in order first.
The industrial corridor and its pipes
The manufacturing and distribution belt that runs through Vernon, Commerce, the City of Industry, Santa Fe Springs and the harbor area was built out from the 1920s through the 1970s, and much of the drainage under those plants dates from the original construction. Cast iron under the floor, vitrified clay and concrete in the yard, and corrugated metal storm lines under the truck courts. A facility in Burbank with that vintage of pipe is overdue for a camera survey whether or not anything has backed up yet, because the first symptom of a collapsed industrial line is often a sinkhole under a forklift lane.
Sanitary, process and storm lines are three different jobs
The sanitary lateral from the restrooms and break rooms is an ordinary sewer, lined the same way a house line is, only larger. Process drains carry whatever the plant produces, and the resin, the liner thickness and the cure are chosen for that exposure, with the material data sheets attached to the proposal. Storm drains under the yard are usually large, shallow and corrugated metal that has rusted through at the invert; they are lined in dry weather with a liner designed for the soil load rather than for pressure. A contractor who quotes all three with one method and one resin has not looked closely enough. The industrial service summary for Burbank is on the TSR Trenchless, Inc. industrial services page for Burbank.
Keeping the plant running
Industrial lining is scheduled around production, not the other way round. Bypass pumping carries flow past the section being repaired, the liner is installed and cured during a shift change or a planned maintenance window, and branch connections are reopened before the next shift. Long runs are broken into segments at manholes or cleanouts so no part of the plant is without drainage for more than the cure time. Night and weekend work is normal for this class of property.
Permits and the Sanitation Districts
Most industrial sites in Los Angeles County discharge to a Sanitation Districts trunk sewer under an industrial wastewater permit, and that permit has conditions about the discharge line and about bypassing. Repairs that alter the connection or require pumping around a meter are reported before the work. Separately, the city or the county issues the excavation permit for anything in the public way. The contractor handles the construction permits; the permit holder handles the discharge notice, with the contractor supplying the schedule and method statement.
Specifying the work
Industrial lining is bought on a specification rather than a handshake. The plant engineer or facilities manager in Burbank should expect the proposal to state the liner thickness and the design basis for it, the resin system and its chemical resistance data, the cure method and the acceptance test, usually a post-cure camera pass and sometimes a sample coupon from the liner end. Where the facility is under a corporate standard or an insurer's requirement, those documents go to the contractor before the quote. Bids that arrive without a design basis are not comparable with ones that have it, and the difference usually shows up in the thickness.
Access, safety and the site
Industrial lining crews work from manholes and cleanouts, so confined space entry procedures, lockout of adjacent process lines and the site's own safety orientation apply. Expect the crew to ask for a site induction, a hot work permit if a steam cure is used, and a traffic plan for the yard. Rail spurs, crane paths and hazardous material storage near the line are flagged on the survey drawing before the method is chosen.
The deliverables
An industrial job closes with a survey drawing showing each lined segment, pre- and post-installation video for every segment, the resin and liner certifications, cure logs where the specification requires them, permit sign-offs and a warranty that names the segments. Plant engineering keeps the package with the facility's drawings. County-wide coverage, including the harbor and the Antelope Valley, is described at the Los Angeles County service hub, and the standards the lining trade works to are set out at the cured-in-place pipe reference site.

Industrial services in Burbank
Trenchless Sewer Repair
Repair or replace a failed sewer line with little or no excavation.
Sewer Pipe Lining (CIPP)
A resin-saturated liner cured in place forms a new, jointless pipe inside the old one.
Pipe Bursting
A bursting head splits the old pipe while pulling new HDPE pipe in behind it, through two small pits.
Sectional Point Repair
A short liner fixes one bad spot and leaves the rest of a sound line alone.
Sewer Camera Inspection
See what is actually wrong before anyone quotes a fix.
Hydro Jetting
High-pressure water strips roots, grease and scale so the pipe can be inspected and lined.
Sewer Line Repair & Replacement
When a line cannot be lined: spot excavation or trenchless replacement, chosen from the footage.
Questions about industrial work in Burbank
What pipe sizes can be lined?+
Laterals from four inches up through mains of several feet are lined routinely. Industrial work in Burbank is usually in the six to eighteen inch range, which a felt or glass liner handles with a pull-in or inversion installation and a hot water, steam or ultraviolet cure.
Our drains carry process waste, not just sanitary flow. Does that change the liner?+
It changes the resin. Standard polyester resins suit sanitary sewage; lines carrying solvents, high temperature discharge or low pH waste call for a vinyl ester or epoxy system rated for that exposure. Tell the contractor what goes down the drain and ask for the resin data sheet in the proposal.
Do we need to notify the Sanitation Districts?+
If the facility holds an industrial wastewater discharge permit from the Los Angeles County Sanitation Districts, repairs to the permitted discharge line and any bypass pumping during the work usually need to be reported. The contractor coordinates the timing; the permit holder makes the notification.
Can the plant keep running during the repair?+
Usually. A bypass pump carries flow around the section being lined, and the cure is timed for a shift change or a planned shutdown. Storm lines are lined in the dry season. The work is sequenced so no production drain is out of service without a bypass in place.
How is an industrial job quoted?+
From a camera survey of the lines in question, with the recording and a condition report delivered first. Call (310) 340-2515 or send the form with the site address and a contact for plant engineering. Estimates are free; call now.
