Client Name: City of Santa Ana I AMI FEASIBILITY REPORT 3.2.2.2 Meter Data Management MDMS (Meter Data Management System) is required to cleanse (Validation, Estimation and Editing - VEE) raw meter data. MDMS will integrate with the AMI system to store meter reads, alarms and flags received from the meters. This will then apply a variety of business rules on the data before the processed information is delivered to the billing system. MDMS can also be used during the deployment process to facilitate migration to the new AMI system. AMI vendors offer hosted solutions that include AMI HES and MDMS. MDMS can also be procured directly from vendors that sell such products. City must ensure that the MDMS is able to meet the minimum requirements of the City to cleanse and store data for billing and analytics. 3.2.2.3 Work Order Generation To support the AMI project meter and MTU deployment activity, the work order management system (WOMS) used by the chosen deployment vendor will need to be integrated into City's systems during the deployment. City will need to investigate the work flows and impact of this integration to determine the optimum design during the detailed planning stage of the AMI project. 3.2.2.4 Geographical Information System (GIS) AMI vendors offer the collection of GIS coordinates of meters and network devices that can be stored in GIS and other systems like CIS (Customer Information System), MDMS etc. City will have to evaluate the processes with the AMI vendor to make full use of this opportunity to capture meter and field device coordinates in the existing GIS. AMI vendors may offer mapping capability to show meters and network devices status on maps. It is important to gather the GIS coordinates if this functionality is available as it can provide a visual representation of the network and is useful information about field assets. 3.2.2.5 Customer Data Presentation AMI data is recorded in terms of hourly intervals (and can be 15 minutes for large customers if required). The hourly meter reads for the day collected in the night and are displayed to the customers on web portal. This customer data presentation helps the customers understand their usage and can help in educating them regarding conservation. Data presentation can also provide details about leakage or excessive usage to the customers, and links to water conservation programs, online billing and other features can be provided as additional benefits. Vendors offer cloud based hosted solutions that can gather data from the AMI HES or MDMS and present data to the customers. Certain vendors even offer services like hosted MDMS and customer portal together at competitive rates. City must evaluate all of these available options if hosting of the customer portal by City is not cost effective. 4 Current Metering Platform 4.1 BI -MONTHLY BILLING Most of the City customer meters are read and billed bi-monthly. As with many water utilities, the wholesale migration of all customers to monthly meter reading and billing has been cost BLACK & VEATCH I Current Metering Platform 2513-127
