Grinder Pump Alarm Monitoring


The Grinder Pump Guardian system is designed to monitor a whole neighborhood of low pressure sewer pumps at once. The GPG remote module is installed in each pump control panel and an HTT-1100 unit is installed somewhere in the neighborhood to manage the messages from up to 180 GPG remotes. Each remote reports to the collector if there is a pump station alarm or if there is an excessive pump runtime alert. The collector relays those messages to the High Tide servers which then send out alarms to the operators. The collector can also be used to monitor a lift station that is in the neighborhood. The GPG remotes use a 900MHZ ISM band radio mesh network to communicate. Each GPG remote functions as a repeater and has a range of between 500 feet and half-mile depending on terrain and vegetation density. The collector also polls every remote once per hour to verify that they have power and are functioning normally.

The TelemetryVIEW web interface gives the operators tools to know exactly where there are problems and schedule service calls appropriately. Service history can also be maintained on the same system.
