ABSTRACT:
An aircraft (10) having a cabin (14) with a plurality of potable-water-using stations (22) that drain graywater to a transfer tank (24). The graywater ejection system pressurizes the transfer tank (24) at appropriate times and/or places, so that graywater can be ejected through a drainmast (26) without the help of gravity. This graywater ejection system eliminates the need for a discharge line from the transfer tank (24) and frees the aircraft's fuselage (12) from having an inconvenient port associated with such a discharge line.
