SYSTEM EVALUATION, CAPACITY ASSURANCE, CAPITAL IMPROVEMENTS © 2025 Fischer Compliance, LLC. All rights reserved. Sewer System Management Plan licensed for San Leandro use only. Page 43 of 57 COMPLIANCE The above requirements are addressed below: System Evaluation: The City’s collection system evaluation involves every component of the City collection system, including pipelines, manholes, and pump stations. It is of key importance to regularly perform pipeline condition assessments to initially establish a baseline condition and to monitor changes over time. The City uses visual inspections, CCTV inspections, and spill data to evaluate the performance of system assets and adjust as necessary. Justify the amount of system assessed each year: The City has maintained its system with a low spill rate and cleans most of the system yearly. The City has not yet determined the optimal cleaning interval or CCTV inspection interval. Once a CCTV inspection has been completed for the entire system, staff will evaluate the findings to determine the optimal inspection frequency. Prioritize condition assessment areas: The City considers that most of its collection system has roughly the same environmental risk. Therefore, the City does not currently prioritize condition assessments based on environmental consequences or proximity to surface waters but intends to do so in the future. Assess system using visual observations, etc.: The City assesses system conditions using visual observation and video surveillance. Evidence of flow exiting from system: The City is currently not aware of any exiting of sewage from the collection system. The City actively inspects and maintains its collection system to prevent sewage from exiting and impacting the environment. Maintain documents: The City documents all inspections, maintenance, and evaluations of the sewer system using its CMMS and GIS programs. These documents are maintained at the City offices or in the CMMS program. Climate change: The 2015 Capacity Study includes a study of expected wet weather flows but does not include an assessment of how climate change may affect storm intensity. The City intends to evaluate the potential for increased spills due to higher flows and I/I from increased storm intensity through completion of a “climate assessment” specific to the sanitary sewer system and Water Pollution Control Plant. The City will continue to review the potential impacts of climate change and will update this section as needed.
