Brush Creek Area 1
Neighborhood Sewer Rehabilitation:
Existing Data Review
EAE reviewed pipe locations, known chronic water-in-basement areas, and CCTV inspection forms and condition assessments to prioritize pipes for further review in accordance with KCMO's Neighborhood Sewer Rehabilitation – Risk Based Prioritization and Rehabilitation Recommendation Technical Memorandum, December 2015. An Access database was used to record the reviews of each prioritized pipe segment.
Five EAE National Association of Sewer Service Companies (NASSCO) Pipeline Assessment Certification Program (PACP®) and Manhole Assessment Certification (MACP®) certified staff participated in reviews of CCTV footage of prioritized pipe segments.
Recommendations were provided for point repairs for localized defects and complete pipe segment replacement or Cured-In-Place Pipe (CIPP) lining based on the observed pipe structural condition.
Laterals and intruding laterals were identified and recommended for open-cut repair or full wrap short liner, as necessary.
The KCMO GIS system was accessed to compare pipe sizes documented in the GIS system versus photographs of measurements taken during the CCTV surveys.
An updated ArcGIS 10.x geodatabase was developed following the KCMO geodatabase schema incorporating information from the CCTV review, pipe size verification, smoke testing, and dye testing performed by others.
