y of Santa Ana Section 4: Operation and Maintenance Pro, 4.2.2 Lift Station/Force Mains In addition to the crews maintaining the gravity sewer system, the City's Water Production staff supports maintenance of the two sewer lift stations and the force mains are cleaned as needed. Water Production Operators are cross -trained to assist with the maintenance of these pump systems. Maintenance activities include weekly inspections of each lift station, along with periodic equipment servicing consistent with equipment manufacturer's recommendations and industry standards/best practices. 4.2.3 Sewer Lateral Maintenance Property owners are responsible for the maintenance, operation, cleaning, repair and reconstruction of sewer laterals. In an effort to prevent sewer pipe blockages and damage, the City distributes sewer lateral maintenance flyers to the public that contain information about grease and roots management, an example is provided as Appendix H. In some cases, if warranted, the City can assist property owners with sewer lateral repairs or replacement for those laterals that connect to the City's sewer system, have a cleanout to allow access for inspection equipment and are free of debris through the lateral assistance program. 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. 4.3 Training City sewer system operations and maintenance personnel are trained on the requirements of the WDR Order No. 2022-0103, and are generally trained in-house/on-the-job to execute collection system maintenance tasks, as well as the Spill Emergency Response Plan procedures and practice drills. Equipment vendors provide additional training for specific equipment or components. When feasible, field crews also attend seminars and/or conferences for additional training opportunities. In addition, all staff attend monthly safety trainings. Staff that are responsible for submitting data receive additional training on electronic CIWQS procedures. 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. Field operators receive skilled spill volume estimation training. 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. 4.4 Equipment Inventory 4.4.1 Lift Station Inventory Each of the two sewer lift stations are 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. 4.4.2 Equipment 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 situations. 2025 4-10
