PowerSewer - ESP Service Agreement - Page 6

ESP Program

Interon™ offers four maintenance programs for the PowerSewer™. Each of these options are designed to anticipate failures to limit the possibility of homeowner inconvenience.

ESP I: Data Acquisition and Field Service

This program is custom designed software that permits a field service technician to download performance data directly from the PowerSewer into a personal computer. The ability to download the PowerSewer performance data provides a means of collecting information for analysis and troubleshooting. ESP-I software also allows field adjustment to the PowerSewer Control System.

ESP II: Monitoring Service

This program is a monitoring service provided by Interon. The PowerSewer is equipped with the modem module to transmit (via telephone line) any alarm conditions or performance data to the Interon Service Center. Here, trained technicians will analyze the transmitted data and make an attempt to correct the condition by transmitting a series of commands. If the alarm condition cannot be remedied by telephone, a field service technician will be dispatched.

ESP III: Maintenance Service

This option is like that of the ESP II contract service except that Interon would take total responsibility to prevent and to satisfy any alarm condition from a PowerSewer. This service is designed to eliminate the need for the homeowner and/or municipality to be involved in the event of a PowerSewer equipment failure.

ESP IV: Self-Monitoring

This option allows a municipality or a service company to monitor and provide service for a large network of PowerSewers. This service option requires the purchase of the PowerSewer Modems and Monitoring Software.

In addition to reporting alarm conditions, the PowerSewer is programmed to periodically transmit all performance conditions to the Service Center for a system performance evaluation. This predictive maintenance monitoring program can diagnose the condition of the PowerSewer system and determine if any field service calls will be required in the near future. This performance evaluation will minimize system interruptions and inconvenience to the homeowners.
