4.3.1.3 Energy management program. The utility shall review and opti- mize electrical usage at regular intervals, including review of energy trends and costs, and shall consider energy cost in the evaluation of new or replacement system components.
4.3.2 Asset management plan. The utility shall have an asset manage- ment program that supports capital improvement planning and operation and maintenance activities by determining existing conditions, setting future goals, and tracking progress.
4.3.2.1 Asset inventory. The utility shall have an accurate, up-to-date tracking list and/or map of the system, showing all gravity line segments and struc- tures (manholes, cleanouts, lif stations, force mains, and other applicable waste- water conveyance facilities owned and maintained by the utility). Assets that have been retired and are still in place should be included in tracking and/or map as applicable.
4.3.2.2 Asset information. Critical information about the assets should be included in the tracking list, either in a computerized maintenance manage- ment system (CMMS), geographic information system (GIS), or other available elecronic format, and should be easily accessible. Critical information should include, as a minimum, asset identification number and description, diameter/size, material, installation date, address or location information, manufacturer model, and serial number as applicable.
4.3.3.1.1 Combined sewer overflows (CSOs). The utility or service pro- vider shall have a program that monitors, mitigates, and reduces the total number of combined sewer overflows experienced. Service provider personnel should be consistently trained in the CSO mitigation and documentation process. In order to reduce the total number of these types of discharges to be in compliance with applicable requirements and/or system capacities, the utility should employ the use of proactive closed-circuit television (CCTV) and physical inspections of man- holes and other assets prone to these conditions.' The frequency of these proactive inspections should be determined based on the overAow data collected, the“hot spots”identifed, and the goals of the organization. The results of these inspections should be documented and modifed as necessary to reduce the overall number of overflows.ANSI AWWA G520-17 pdf download.
