What the recording should show
The inspection record should identify direction and distance, pipe material when visible, roots, offsets, breaks, standing water, collapse, and a measured location tied to any repair recommendation.
What remains unknown
Poor access, dirty water, heavy roots, or a blocked section can hide downstream conditions. Written findings should separate what was seen from what could not be inspected.
Maintenance and structural findings are different
NASSCO's condition framework separates operation-and-maintenance findings from structural defects. That distinction helps explain why cleaning, monitoring, focused repair, rehabilitation, or replacement can be different answers.
What the estimate should include
A repair estimate should use the recorded defect, location, footage, depth when available, access, method, restoration, and limits of the inspection.
