Phase III of the Automated Meter Infrastructure Project

Phase III will replace the remaining 7,572 meters in the system with smart meters and transceivers
bringing the total number of smart points to 12,637 which includes every meter in our distribution
system. The total conversion to AMI by replacing the existing water meters will be distributed
over three years, completing approximately 2,500 meter upgrades each year. The completion of
this Phase will result in full Automated Meter Infrastructure functionality district wide.

Phase IV of the Automated Meter Infrastructure Project

Consider expansion of our smart grid system to include Smart Lighting, System Control and Data
Acquisition [SCADA] telemetry to take advantage of the Districts Fixed Base Infrastructure.

Project Timeline of AMI with Grant Funding – Phase I through IV

Phase I of the Automated Meter Infrastructure Project

Install 5,065 AMI capable meters throughout the District. [Complete]

Phase II of the Automated Meter Infrastructure Project (Year 1)

Install three tower gateway base stations, required transceivers and establish the regional
network interface thus activating the 5,065 meters installed in Phase I. The three TGBs will be
located at existing water reservoir tanks and are responsible for gathering data from the smart
meters via a licensed radio frequency, then back load the compiled data to the RNI via a cellular
network. Additionally, the existing 5,065 AMI capable meters currently installed will each be
outfitted with a transceiver that will be mounted into an upgraded meter box lid. Then, the regional
network interface will be established to integrate the incoming meter data and the existing
customer billing system.

Phase III of the Automated Meter Infrastructure Project (Years 2-3)

Phase III will replace the remaining 7,572 meters in the system with smart meters and transceivers
bringing the total number of smart points to 12,637 which includes every meter in our distribution
system. The total conversion to AMI by replacing the existing water meters will be distributed
over two years, completing approximately 3,750 meter upgrades each year. The completion of
this Phase will result in full Automated Meter Infrastructure functionality district wide.

Phase IV of the Automated Meter Infrastructure Project (Undetermined)

Consider expansion of our smart grid system to include Smart Lighting, System Control and Data
Acquisition [SCADA] telemetry to take advantage of the District’s Fixed Base Infrastructure.
