7 of Santa Ana Section 4: Operations and Maintenance Pro <br />Association of Sewer Service Companies (NASSCO), to classify the condition of the sewer line. Sewer segments <br />with the most severe structural ratings are prioritized for rehabilitation and/or replacement; therefore, this <br />baseline CCTV inspection data serves as the basis for the City's Rehabilitation and Replacement plan. Additional <br />details of the processes and criteria for condition assessment activities are included in the City's Sewer System <br />Operations and Maintenance Manual. <br />Even though the City is not responsible for the maintenance of private sewer laterals, the City has a Sewer <br />Lateral Replacement and Repair Program (SLRRP) to assist customers with sewer lateral repairs within the <br />public right-of-way. CCTV inspections are often used to evaluate the root growth and determine the appropriate <br />mitigation measures for each stretch of impacted sewer mainlines. <br />Two separate funds support the City's Capital Improvement Program (CIP). The Sanitary Sewer Service fund is <br />allocated for maintenance, rehabilitation and repair and replacement of sanitary sewer facilities, as well as <br />emergency response to sewer blockage issues. The Sewer Connection Fee fund is allocated solely for the <br />construction of sewer capacity enhancements. The City balances the rehabilitation projects on a year-to-year <br />basis and aims to improve the operating efficiency and life expectancy of the entire sewer system. Sewer service <br />rates are periodically reviewed and adjusted to address identified CIP needs. <br />4.2.4 Staff Training <br />City sewer maintenance personnel are generally trained in-house/on-the-job to execute collection system <br />maintenance tasks, as well as responding to system emergencies. Equipment vendors provide additional <br />training for specific equipment or components. When feasible, field crews also attend seminars and/or <br />conferences for additional training opportunities. In addition, all staff attend monthly safety trainings. <br />Water production staff also receive on-the-job and equipment vendor training to operate and maintain all City <br />pumping facilities and related equipment, including the two sewer lift stations. Although not required, City <br />maintenance staff are encouraged to obtain California Water Environment Agency (CWEA) training and <br />certification. Several staff members have received certification through this program. <br />4.2.5 Equipment Inventory <br />4.2.5.1 Lift Stationlnventory <br />Each of the two sewer lift stations is equipped with redundant pumps. Therefore, should one pump experience <br />reduced performance or a mechanical failure, the redundant pump will automatically start. Both lift stations <br />are equipped with automatic backup emergency diesel generators for use during power failures. The City <br />additionally has a stand-by bypass pump that can be deployed to any lift station if needed. <br />4.2.5.2 Equipment Inventory <br />An inventory of pipe and equipment is stored at the City's Corporate Yard for use by maintenance crews to <br />make repairs to smaller sewer mains and laterals. The City maintains a Call -Out Vehicle with all necessary, back- <br />up materials, including plugs. In addition, the City has an on -call Contractor available to support emergency <br />situations. <br />4.3 Supporting Documents <br />The following documents, attached as appendices, support the City's Operation and Maintenance Program, <br />thereby allowing the City to comply with the Operation and Maintenance Program requirements of the WDR: <br />April 2020 4-4 <br />19F-22 <br />
