One of the most prevalent telemetry strategies in the water and wastewater industries is the "Master-Slave" scheme. In a "Master-Slave" network, all remote RTU's report their status to a central computer, which then returns the control commands. However, if the central computer is down for any reason (e.g. power outage or repairs), the entire control network stops functioning. This can be catastrophic for rural water or wastewater districts which are often spread out over hundreds or even thousands of square miles. Navionics has been committed, from the beginning, to a rejection of "Master-Slave" schemes in favor of providing fault-tolerant "Peer-To-Peer" telemetry and control systems. In a "Peer-to-Peer" network, all RTU's operate in a smart, stand-alone mode at all times. Just ask Raccoon Water Company of Centralia, IL. When a tornado damaged their main office in April of 1998, their C3 computer was without power for 3 days. However, while they were busy repairing the office, their remote water towers and pump stations, which did have power, continued to operate as normal - keeping all customers supplied with water. In the face of a natural disaster, their telemetry and control system was one thing they didn't have to worry about. After all, the measure of a fault-tolerant system is how well it operates under less-than-ideal conditions.
