Drain Camera Inspections: What Should the Video Actually Answer?
A drain camera inspection should answer a defined question about an identified pipe, not simply produce a video. Before authorizing the work, agree on the section to be inspected, the records you will receive, and how any uninspected portion will be reported. Ask the provider to separate visible findings from conclusions that require other investigation.
Start with the decision, not the equipment
Perhaps a buried storm drain keeps causing concern, or a proposed repair includes replacing a pipe you have never seen. Write down the decision you hope the inspection will support: whether a specific section needs further investigation, whether an apparent obstruction is present, or what evidence supports the replacement recommendation. Those are more useful instructions than asking someone to check everything.
Give the provider a marked property sketch and any available pipe records. Identify the line by its endpoints or nearby permanent landmarks rather than an informal name such as the back drain. Ask the provider to confirm that the proposed equipment and access arrangements suit that particular line. Do not assume a quoted inspection includes every connected branch.
Understand what an ordinary camera cannot certify
EPA's report on wastewater collection system assessment describes conventional CCTV as a way to examine interior pipe surfaces. It can reveal visible cracks, displaced joints, roots, and debris. The same report explains that ordinary CCTV does not establish pipe-wall integrity or show the soil supporting the pipe; water level, image quality, and interpretation also affect the assessment.
That report concerns wastewater infrastructure, not a design specification for your property's storm drain. Its useful lesson for an owner is narrower: ask what was actually visible. A clear image of one section is not a certificate for the entire buried system. Have the provider explain which of those limitations apply to the equipment and conditions on your project.
Agree on a small, usable inspection package
Request the complete recording, a short written summary, and a sketch identifying the inspected segment. Ask for the inspection date, entry point, direction of travel, and a consistent way to locate each reported finding in the recording. A still image can highlight a concern, but it should not be the only record you receive when the full video is part of the agreed scope.
Add three questions to the work order: Where did the inspection begin and end? Was the intended segment completed? Which areas could not be assessed? Ask that the summary distinguish an observed defect, a suspected condition, and an unanswered question. These are practical purchasing requests, not a claim that every provider uses the same reporting format.
Discuss how incomplete work will be handled before the visit. Who will contact you if access is unavailable or the inspection cannot continue? What additional work requires a separate authorization? Ask for an explanation and price before approving a return visit or a changed scope. Keep inspection authorization separate from permission to excavate or replace the pipe.
Turn findings into a reviewable next step
When reviewing a repair recommendation, ask the provider to point to the finding that supports it. Request a marked repair location and an explanation of what remains uncertain. If the report stops short of the area you were concerned about, retain that as an open item rather than describing the whole line as inspected.
Use a simple handoff note: the original question, the evidence received, the recommended action, and the person responsible for the next decision. For a commercial property, keep that note with the proposal so an owner, manager, and maintenance vendor are discussing the same segment. Save the original recording rather than relying only on a temporary viewing link.
For a Middle Tennessee property, Milliken Corporation lists storm drains, drain pipe installation, and drainage repairs among its services. Share an existing inspection package when discussing drainage work. Confirm separately whether camera inspection is available or needs another provider; the company's drainage service listing alone does not establish that equipment or service.
Frequently asked questions
Does a camera inspection include repairs?
Do not assume it does. Ask the proposal to distinguish inspection, any preparatory work, reporting, and repairs. Specify who may approve added work before the visit.
What if the video does not reach the end of the pipe?
Ask for the stopping point, reason, and uninspected extent to be documented. Have the provider propose a next step for the unanswered question rather than treating an incomplete inspection as a complete result.
Should I send the video when requesting a repair proposal?
Yes, along with the written report and location sketch. Explain the decision you need to make, and ask whether the receiving contractor needs further site investigation before defining the repair scope.
