CCTV sewer inspection and condition assessment in Charlotte
No reach of sewer in Charlotte should be specified, bid or repaired on the strength of a symptom. A CCTV inspection with standardized coding gives a facility manager or utility engineer the record every other decision depends on. This page explains what a proper survey includes and how to read it.

The record everything else depends on
A sewer line is the one asset a Charlotte facility owns that no one can walk up and look at. The CCTV survey stands in for that look. A camera is pushed or driven through the pipe, recording continuously with a distance counter on screen, and a trained operator codes every observation against a standard. The resulting video and report become the basis for the repair method, the bid, the permit application, the warranty baseline and, years later, the next survey's comparison. A proposal written without it is a guess, and a specifier should decline to evaluate one.
Equipment matched to the pipe
Building laterals and small site mains in Charlotte are inspected with push cameras: a self-leveling head on a stiff cable run from a cleanout, suited to 3- to 8-inch pipe and a few hundred feet. Collection mains and storm drains are inspected with crawler systems launched from manholes, carrying pan-and-tilt cameras that look directly into joints and service connections. Lateral-launch crawlers send a secondary camera up each service from the main, which is how private-side defects are found on a public system without entering every parcel in Mecklenburg County. Where the pipe is surcharged or too damaged for a camera, sonar and laser profiling measure the bore and debris level instead.
Coding to the PACP standard
The Pipeline Assessment Certification Program gives every observation a code, a distance, a clock position and a grade from one to five. Structural codes cover cracks, fractures, holes, collapse, deformation and joint defects. Operations-and-maintenance codes cover roots, grease, scale, debris and infiltration. Each reach ends up with a quick rating and index scores that let an engineer sort a whole system from worst to best and defend that order to a board or council. Manholes are coded under a companion standard, because their chimneys and benches often leak more groundwater than the pipe between them.
What the footage shows under Charlotte
In the older commercial corridors of Charlotte, an operator expects to see vitrified clay with joints every two to three feet, opened by decades of shrink-swell in Piedmont red clay, with roots and groundwater entering at those joints. Cast iron inside and beneath older buildings shows scale and tuberculation that narrows the bore. Concrete mains show crown loss where hydrogen sulfide has attacked above the waterline, and brick storm structures show missing mortar and displaced units. In the newer suburban growth, PVC shows deflection and joint separation where bedding was poor. After a heavy summer storm, active infiltration is visible as weeping or running water at defects, which is the time to survey a basin suspected of inflow and infiltration.
From survey to program
For a single commercial lateral, the survey leads directly to a method recommendation. For a utility or a campus in Charlotte, it feeds a program. Reaches are ranked by structural grade and consequence of failure, infiltration sources are quantified by flow monitoring and located by smoke or dye testing, and bid packages are assembled by basin. The same database carries forward: after lining or bursting, the post-repair video is coded and stored alongside the original, which is how a warranty claim is evaluated and how the next survey cycle measures what the program achieved.
What the owner receives
The deliverable is the full video of each reach, a coded report with stills at every observation, structural and maintenance grades, and a map or schematic keyed to manhole numbers or cleanout locations. Where repair is warranted, the proposal references the specific observations it addresses, so the owner can match each line item to a frame of footage rather than to a general description. Files are delivered in a format the owner's asset management system can import, and the raw video is retained so a later question about a specific joint can be answered without a second mobilization.

Questions we hear about sewer camera inspection
What does PACP coding add to a plain camera video?+
A standardized vocabulary. Each observation is recorded with a defined code, a distance from the starting manhole, a clock position and a severity grade, and the reach receives structural and operations-and-maintenance scores. That lets a Charlotte owner compare reaches, sort a whole system by condition, and hand a bidder a report every contractor interprets the same way.
How is a long collection main inspected?+
With a tractor-mounted pan-and-tilt camera launched from a manhole and driven the length of the reach, recording continuously with on-screen distance. Where flow is high, it is scheduled at low-flow hours or plugged briefly. Laterals can be inspected from the main with a lateral-launch camera, which is how a Mecklenburg County utility finds private-side infiltration without entering every property.
Does the line need to be cleaned before the inspection?+
For a condition assessment, yes. Grease, scale and debris hide the pipe wall, and a survey of a dirty line records the dirt, not the defects. Hydro jetting ahead of the camera is standard on commercial and municipal work in Charlotte. For a quick diagnostic of an active blockage the camera may go in first to find the obstruction.
What else is inspected besides the pipe?+
Manholes, coded under a parallel standard, because chimneys, frames and benches are frequent infiltration points. Smoke testing and dye testing locate illicit connections and inflow sources. Flow monitoring quantifies wet-weather response by basin. Together they turn a video into an infiltration and inflow program a Charlotte utility can prioritize.
