A professional sewer closed-circuit television (CCTV) inspection report is a legal, technical, and commercial document. Whether delivered to a prospective homebuyer during real estate due diligence, an insurance adjuster evaluating flood claims, or a municipal engineering department designing capital improvement projects, a comprehensive inspection report must adhere to rigorous documentation standards to provide actionable, defensible findings.
The 6 Mandatory Components of a Professional Sewer Inspection Report
1. Header Metadata & Administrative Identification
- Property & Asset Identification: Complete street address, property owner/client name, inspector name, and NASSCO PACP/LACP certification number (for municipal/commercial work).
- Inspection Timestamp & Weather Conditions: Exact date, start/end time, and recent rainfall data (critical for evaluating groundwater infiltration vs surface runoff).
- Pipe Material, Diameter & Access Portal: Documented nominal pipe diameter (e.g. 4-inch), pipe fabric (Vitrified Clay, Cast Iron, PVC, ABS, Orangeburg), and specific cleanout entry location.
2. Continuous Video Recording with Embedded Telemetry Overlay
The primary inspection deliverable is an unedited high-definition (1080P) MP4 video file featuring permanent On-Screen Display (OSD) telemetry:
- Live digital distance counter (in linear feet or meters).
- Date and time stamp.
- Spoken audio narration explaining observed pipe conditions.
3. Standardized Defect Observation Log (PACP / Trade Scoring)
Every observed condition along the pipeline run must be logged with precise spatial coordinates:
- Exact Footage Location: Linear distance from starting cleanout.
- Clock-Position Coordinates: Circumferential orientation (e.g. “Crack from 10:00 to 2:00”).
- Defect Classification & Severity Grade: Categorized by structural defects (cracks, fractures, broken hubs), O&M defects (roots, grease, scale), or construction features (tees, wyes, transitions).
4. High-Resolution Photographic Defect Captures
Embedded still photographs capturing every major defect under focused LED illumination, with callout arrows and descriptive captions explaining the structural implication.
5. Surface Locating Depth & Alignment Map
When significant defects (e.g. collapsed sections, root blockages, pipe bellies) require excavation, the report must include surface locating data captured via the camera’s 512 Hz sonde:
- Exact surface dig marks relative to permanent landmarks (e.g. “14.5 ft from front porch, 3.2 ft deep in front lawn”).
- GPS coordinates or annotated aerial site map.
6. Professional Recommendations & Actionable Next Steps
A concise summary separating immediate emergency action items from routine preventative maintenance:
- Distinguishes maintenance cleaning (hydro-jetting, mechanical snaking) from structural rehabilitation (trenchless CIPP point repair, pipe bursting, open-trench excavation).
- Avoids speculative engineering claims; clearly states when conclusions require further evaluation by a licensed professional engineer or plumbing contractor.

Legal & Contractual Defensibility of Inspection Reports
Professional inspection reports often serve as critical evidence in real estate negotiations, municipal contractor disputes, and insurance flood claims:
- Indelible Timestamp & Footage Overlay: Continuous video stamping proves that footage was recorded on the stated date and represents a continuous, un-spliced run.
- Objective vs Speculative Phrasing: Defensible reports state objective visual facts (e.g. “Heavy root mass occupying approx. 60% of cross-sectional area at 42.1 ft”) rather than speculative fault attributions.
- Standardized Defect Photos: Include high-contrast still photographs with clear caption callouts alongside video links.
Frequently Asked Questions About Sewer Inspection Reports
What video resolution should be provided in a modern sewer inspection report?
Modern professional reports should provide high-definition 1080P (1920×1080) MP4 video files with embedded distance telemetry, clear date/time stamps, and audible inspector narration.
Why is a 512 Hz sonde surface location map necessary in an inspection report?
When major structural defects (such as collapses or severe root intrusions) require excavation, providing exact surface depth and landmark measurements ensures contractors can excavate directly over the defect without digging exploratory trenches.
