WHY THIS WORKFLOW
Sewer CCTV inspection is an effective way to see the underground footage, findings, location, status, and report, and stay connected from field capture to review.
For dry sewer lines, a sewer inspection crawler carries the CCTV workflow through the pipe while the field team records the inspection from outside the line.
Dry sewer, large-diameter dry main line, and large-diameter wet main line do not receive the same deployment. The tool is selected around the condition and scale recorded in the scope.
Terra SewerX connects findings to their pipe section and inspection position, giving the review team a clearer line from video evidence to the reported location.
Track inspection progress across the network so planned, inspected, reviewed, and closed work is easier to follow in one reporting workflow.
The reporting software assembles verified findings, locations, and evidence into a structured report workflow instead of rebuilding each observation in a separate document.
The software can auto-detect potential defects, but an inspector verifies each finding before it is included in the client report.
تحديات
A useful inspection record needs more than video: the team must know which section was covered and where a finding sits along it.
The primary dry-sewer crawler workflow is not the same as a wet large-diameter main-line deployment. Pipe condition and diameter shape the method.
When the main line is large in diameter, the inspection plan may require a different platform for a dry or wet condition. The scope is selected before mobilization.
CCTV footage, defect notes, locations, and status updates lose value when they live in separate files. A central reporting workflow keeps the inspection record connected.
A network programme needs a repeatable way to move from a finding to its section, evidence, status, and report. One reporting workspace keeps those steps in the same place.
The purpose of localization and reporting is a clearer handoff from inspection findings to the team deciding what happens next.
التقنيات و الأساليب
For dry sewer lines, the crawler platform supports DN190–DN2000 pipes and up to 120 m working distance. Final deployment depends on pipe condition and access.
For large-diameter dry mains, the inspection uses a dry-line deployment matched to the pipe condition, diameter, and available access.
For large-diameter wet mains, a wet-line inspection platform captures pipe condition while the field team records the inspected section.
The reporting software connects CCTV evidence to AI-assisted findings, inspector verification, localization, network progress, and structured client reporting.
