Written by GovTribe AI ·

This document contains a detailed sewer pipe inspection report from Pipe Tec for a project in DEVA-NP (likely Death Valley National Park) on 6/8/2023. The report covers eight separate pipe segment inspections between multiple manholes (MH-008 to MH-005), utilizing different pipe materials including Vitrified Clay Pipe (VCP), Polyvinyl Chloride (PVC), and Cast Iron. The total length surveyed was 511 linear feet across various pipe segments, with pipe sizes ranging from 6 to 8 inches.

Key findings from the inspections reveal significant issues in multiple pipe segments, including severe debris obstructions, joint offsets and separations, line misalignments, and corrosion. Several inspections were abandoned due to severe debris and poor pipe conditions. The survey was conducted by R. Vargas under dry weather conditions, with no pre-cleaning performed. The purpose of the investigation was a pre-rehabilitation survey for sanitary sewage pipes, suggesting potential upcoming maintenance or replacement work may be necessary given the extensive pipe degradation observed.
