of Santa Ana Section 4: operations and Maintenance Pro This section of the SSMP presents the City's wastewater collection system operations and maintenance (0 &M) program. The summarized requirements for the Operations and Maintenance Program are: 1) Maintain an up -to -date map of the sanitary sewer system, showing all gravity line segments and manholes, pumping facilities, pressure pipes and valves, and applicable storm water conveyance facilities; 2) Describe routine preventive operation and maintenance activities by staff and contractors, including a system for scheduling regular maintenance and cleaning of the sanitary sewer system with more frequent cleaning and maintenance targeted at known problem areas. The Preventative Maintenance (PM) program should have a system to document scheduled and conducted activities, such as work orders; 3) Develop a rehabilitation and replacement plan to identify and prioritize system deficiencies and implement short -term and long -term rehabilitation actions to address each deficiency. The program should include regular visual and TV inspections of manholes and sewer pipes, and a system for ranking the condition of sewer pipes and scheduling rehabilitation. Rehabilitation and replacement should focus on sewer pipes that are at risk of collapse or prone to more frequent blockages due to pipe defects. Finally, the rehabilitation and replacement plan should include a capital improvement plan that addresses proper management and protection of the infrastructure assets. The plan shall include a time schedule for implementing the short- and long -term plans plus a schedule for developing the funds needed forthe capital improvement plan; 4) Provide training on a regular basis for staff in sanitary sewer system operations and maintenance, and require contractors to be appropriately trained; and 5) Provide equipment and replacement part inventories, including identification of critical replacement parts. The City has created and maintains maps of the sanitary sewer system and has established a routine cleaning frequency for the gravity sewer mains and sewer lift stations. The City also identifies areas of the sewer system that may require rehabilitation or replacement, and has prioritized those locations for either repairs or replacement in the City's capital improvement plan. The City also provides routine training for their staff and encourages their staff to acquire all available CWEA certifications. Additionally, the city has created a spare parts inventory for all critical replacement parts. 4.2.1 Mapping The City utilizes a Geographic Information System (GIS) based mapping system to maintain and manage collection system maps and key system attribute data.
