38 AMI Feasibilitv Report I Client Name: City of Santa Ana the availability of the historical data and analytic tools turn the data into useful information and a powerful customer engagement tool. Providing comparison information to educate customers on how their usage compares with their peers helps them identify potential equipment problems or leaks. Delivering the notifications and information in easy-to-use formats has proven valuable and impactful in the industry. 8.3 RAW AND PROCESSED DATA The AMI system will collect the raw data from the water meter MTUs. There is some data validation and error handling done in the AMI systems, but most data management is performed by the MDMS. The raw data from the AMI system is sent to the MDMS, where it is processed. The raw data is always maintained in their original form and never manipulated. If the MDMS must make modifications to the data as part of its validation, estimation, and editing routines, it creates a new copy of the data and stores both the processed data and raw data. This allows the City to go back to the original data if necessary. 8.4 DATA ANALYTICS In addition to the data analytics capabilities of the MDMS, there are other third -party applications that are designed to take AMI data and perform higher order analytics to assist the City in forecasting water use, optimizing operations of water production facilities, improving electricity management for pumping stations, and similar capabilities. Some of the MDMS vendors offer advanced water analytics capabilities that are separate from their core MDMS solutions but are designed to allow for easier integration and use. 8.5 DATA STORAGE AND SECURITY This is a critical aspect of any information technology project. For AMI systems, security is addressed in several ways. Meter consumption information is securely stored in the meter MTU, requiring a person to have the appropriate tools and authorization to access the meter MTU. The information is then sent across the AMI network in an encrypted fashion; it is not persisted on the network under normal operating conditions for an extended length of time, but is transferred to the AMI HES. The HES, whether on the utility site or hosted, is managed in a secure fashion - both physical and cyber security. Access to the AMI HES, as well as the MDMS will be password -protected and role -based. People can access only the portions of the systems to which they are authorized. The AMI industry has gone to great lengths over the past decade to make the AMI end-to-end systems secure. Additionally, the City's IT Department security practices, architectures, and protocols should be followed. Meter reads and system information is normally maintained in the AMI HES for only 2 to 3 months. The MDMS will normally contain one or more years' worth of interval data, with the exact amount determined by the City data management team. Once the data have aged beyond the time of retention for the MDMS, they are archived to a long-term data repository. This need not be a dedicated data warehouse but can be combined with other City data for long-term storage. 25G-156
