of Santa Ana Section 4: Operations and Maintenance Pro with the most severe structural ratings are prioritized for rehabilitation and /or replacement; therefore, this baseline CCTV inspection data serves as the basis for the City's Rehabilitation and Replacement plan. Additional details of the processes and criteria for condition assessment activities are included in the City's Sewer System Operations and Maintenance Manual. Even though the City is not responsible for the maintenance of private sewer laterals, the City has a Sewer Lateral Replacement and Repair Program (SLRRP) to assist customers with sewer lateral repairs within the public right -of -way. CCTV inspections are often used to evaluate the root growth and determine the appropriate mitigation measures for each stretch of impacted sewer mainlines. Two separate funds support the City's Capital Improvement Program (CIP). The Sanitary Sewer Service fund is allocated for maintenance, rehabilitation and repair of sanitary sewer facilities, as well as emergency response to sewer blockage issues. The Sewer Connection Fee fund is allocated solely for the construction of sewers. The City balances the rehabilitation projects on a year -to -year basis and aims to improve the operating efficiency and life expectancy of the entire sewer system. Sewer service rates are periodically reviewed and adjusted to address identified CIP needs. 4.2.4 Staff Training City sewer maintenance personnel are generally trained in- house /on- the -job to execute collection system maintenance tasks, as well as responding to system emergencies. Equipment vendors provide additional training for specific equipment or components. When feasible, field crews also attend seminars and /or conferences for additional training opportunities. Water production staff also receive on- the -job and equipment vendor training to operate and maintain all City pumping facilities and related equipment, including the two sewer lift stations. Although not required, City maintenance staff are encouraged to obtain California Water Environment Agency (CWEA) training and certification. Several staff members have received certification through this program. 4.2.5 Equipment Inventory 4.2.5.1 Lift Station lnventory Each of the two sewer lift stations is equipped with redundant pumps. Therefore, should one pump experience reduced performance or a mechanical failure, the redundant pump will automatically start. Both lift stations are equipped with automatic backup emergency diesel generators for use during power failures. The City additionally has a stand -by bypass pump that can be deployed to any lift station if needed. 4.2.5.2 Eauturnent Inventory An inventory of pipe and equipment is stored at the City's Corporate Yard for use by maintenance crews to make repairs to smaller sewer mains and laterals. The City maintains a Call -Out Vehicle with all necessary, back -up materials, including plugs. In addition, the City has an on -call Contractor available to support emergency situation. r r The following documents, attached as appendices, support the City's Operation and Maintenance Program, thereby allowing the City to comply with the Operation and Maintenance Program requirements of the WDR: Sewage Spill procedures, the City of Santa Ana, Last Updated October 2013, Appendix C.
