A liquid lubricant sump level management system which includes a scavenge pump circuit communicating with the lubricant sump. A centrifugal deaerator is provided in the circuit. A liquid reservoir is in liquid communication with the deaerator. A sensor is operatively associated with the deaerator for sensing the liquid level condition in the deaerator, and providing for passage of liquid from the deaerator to the reservoir in response to a high liquid level condition and for passage of liquid from the reservoir to the deaerator in response to a low liquid level condition.
