OPERATIONS AND MAINTENANCE PROGRAM © 2025 Fischer Compliance, LLC. All rights reserved. Sewer System Management Plan licensed for San Leandro use only. Page 33 of 57 Critical defects are identified for spot repairs and deteriorated reaches for potential rehabilitation or replacement. A future cleaning frequency can be determined for each pipe reach based on the results of the inspections. Each CCTV video is viewed by a lead Collections System Maintenance Worker, and the pipe is graded per standards outlined in the NASSCO Pipeline Assessment Certification Program (PACP). Using the PACP Code Matrix, each PACP defect code is assigned a condition grade from 1 to 5. Grades are assigned based on potential for further deterioration or pipe failure. Pipe failure is defined as when the pipe can no longer convey the pipe design capacity. After assessment is complete, CCTV videos are uploaded both to ICOM3 and to the t4 Spatial program. t4 Spatial is a cloud-based program that displays Collection System assets, and correlates video to a specific line segment. Each frame in the video can be associated with a specific location on the GIS map. It is expected that the City’s upcoming use of Integrity software will replace t4 Spatial. City Engineering Department staff can search for pipe segments with PACP grades of 3 or higher and view specific portions of video that reveal problem locations of the pipe. This allows the City to put together an accurate list of sewer line point repairs and replacements needed for the following fiscal year. Also, repairs are completed more efficiently due to the City’s ability to provide very accurate locations to contractors for required repairs. Manhole Inspections As part of the focused and cyclic cleaning programs, City Collections staff visually inspect manholes for corrosion, debris or damage around the base, cracks or holes, and condition of manhole steps. Inspections involve a visual assessment of the overall manhole condition and observed deficiencies that could result in I/I. Ratings applied to manhole investigations use the standards of the NASSCO Manhole Condition Assessment Program (MCAP) for each of the manhole structure components including the rim and lid, chimney/cone, bench and channel. Each component is rated as poor, fair, or good condition as a gross determination of construction adequacy of the structure and its component parts. Staff conduct a detailed investigation of manhole conditions when a connecting line segment is defined as a rehab project, and corrections needed to the manhole structure are then included as part of the project work. Pump Station Inspections and Assessment Pump stations are inspected on a weekly basis. Weekly inspections include visual check of the equipment, manual cycling of pumps, checking and cleaning floats, recording hour meter readings, and cleaning off debris. In addition, pump stations receive extensive maintenance each year, which includes cleaning out of sump and removing pumps for inspection and performing repairs if necessary.
