Client Name: City of Santa Ana I AMI FEASIBILITY REPORT expectancies. The 1 inch and 2 inch meters have similar characteristics and, thus, are included in this approach. The larger diameter meters (3 inch and above) will have a shorter lifespan and typically are replaced or refurbished on a shorter schedule and require a specified maintenance program. 4000 3500 v 3000 g 2500 2000 n 1500 5 1000 z 500 Meter Numbers by Install Year ■ Number of Meters Install Year Figure 1 Meter Numbers & Age by Install Year Note: Data for approximately 6,500 meters did not have the install year and is missing in this graph. For all other analysis the install date has been assumed as year 2000. There are about 6,826 new meters less than 10 years old, since these meters are so new, and have not shown any performance issues, these don't need to be replaced and can be easily retrofitted with MTUs (City will have to verify if registers in these meters are compatible with AMI MTUs otherwise the registers will have to be replaced too). Black & Veatch recommends that these newer Badger meters be retrofitted with MTUs. The remaining 37,739 meters should be replaced with new AMI meters (meter and MTU). Figure 2 shows the number of meters by age, Y-axis is on a logarithmic scale for better illustration. The graph shows that a large part of the meters are over 10 years old.
