The Aclara Smart Communications Network Utilizes existing infrastructure Connects directly to and extends the utility enterprise LAN Creates a secure, high-speed, private, wireless, TCP/IP network Built on IEEE standards Simplifies the utility communication strategy Reduces utility overall communication O&M cost AMI/HAN Backhaul Workforce Management Water Distribution SCADA Water towers Regulators/Valves Monitoring system (leak detection) Video surveillance Pump station/pressure station Treatment plant Water Distribution Water tower Regulators Valves Monitoring system (leak detection) Pump station/pressure station Treatment plant SCADA Workforce management AMI Backhaul

Aclara STAR® AMI Network Two-Way Communication System Transmits and receives data Maximizes battery life (20 years; hourly read) Launches a time-synchronized network Works with all meter manufacturers Delivers multiple meter readings from every meter, every day Eliminates estimated bills Allows for timely revenue protection, immediate theft and tamper detection Enables immediate response to customer inquiries Remote connect and disconnect capabilities In-Home Displays

Aclara STAR® ZoneScan™ Leak Detection Aclara STAR ZoneScan uses acoustic leak detection to: Predict and locate leaks in the water system before and after the meter Correct and repair system leaks before they reach catastrophic levels Inform customers on water use and conservation methods This leads to losses of roughly 1.2 million gallons of water per year. That is 6500 gallons of water per day. An international study found that it can take an average of 182 days to learn of a leak…find the leak…and then repair the leak.
