Level control in sewage lift stations is normally provided by two or more pumps, with a level controller to tell the pumps when to start and stop.

A MEDACS unit can field power a Radar gauge mounted in the lift station and provide the switching of the contactors for the pumps. Normally, the duty pump will lower the level, but in storm conditions, the back up pump may be called to assist. After each pump down cycle, a TFML module rotates the duty assignment to ensure both pumps remain active and with even running hours.
