    • A vacuum toilet system comprises a waste-receiving bowl defining an interior space for receiving waste material. A sewer pipe defines an interior space that can be placed at a pressure that is lower than that in the interior space of the waste-receiving bowl, and a discharge valve is connected between the outlet of the waste-receiving bowl and the sewer pipe for controlling passage of material between the waste-receiving bowl and the sewer pipe. A rinse liquid valve controls supply of rinse liquid to the waste-receiving bowl. A controller is responsive to a user stimulus to open and close the discharge valve in accordance with a predetermined cycle, and to open the rinse liquid valve during at least the interval during which the discharge valve is being opened.
