A hardware (e.g., a process and / or circuitry) and / or software-based controller for septic system grinder or chopper units monitors load to the unit. As the unit encounters debris, electrical and mechanical load on the unit increases. In some cases, a signal to stop the unit from grinding / chopping (including but not limited to a signal based a waste-water level) is received while the unit is under the increased load. The controller may override the stop signal and continue sending power to the unit to clear the unit from debris causing increased load. The override may cease when it is determined that the debris has been cleared, such as when it is determined that the increased mechanical and / or electrical load on the unit has decreased or returned to a target load, allowing the unit to stop. The unit may include self-configuration functionality, determining thresholds for signaling override, target load, etc.
