A system and method for reducing water consumption in a vacuum toilet on an aircraft. The system and method includes a weight sensing device that is mounted to an aircraft toilet and is responsive to weight applied to the bowl of the toilet. The weight sensing device detects that a toilet user is seated upon the toilet seat when it measures a weight applied to the toilet bowl. On the other hand, the weight sensing device detects that a toilet user is standing when the weight sensing device does not measure a weight applied to the toilet bowl. A flush control unit is connected to the weight sensing device and controls the amount of water utilized in the flushing of the toilet. When the toilet is flushed and the weight sensing device has detected that a toilet user has sat upon the toilet seat, the flush control unit commands that a standard amount of water be used to remove the solid waste of the toilet user. On the other hand, when the toilet is flushed and the weight sensing device has detected that the toilet user has stood, the flush control unit commands that a small amount of water be used thereby saving water.

[ We claim:] [1.]1. A system for reducing the amount of water consumed in the flushing of a vacuum toilet system in a vehicle, the toilet system including a toilet having a toilet bowl and a supporting frame, the system comprising:a pressure sensor adapted to be mounted to the toilet and responsive to a force applied to the toilet bowl to generate a pressure signal proportional to the amount of force;a pressure derivation circuit connected to the pressure sensor to compare the pressure signal to a threshold value and to generate a standard flush signal if the pressure signal is greater than the threshold value; anda flush control unit connected to the pressure derivation circuit to control the amount of water utilized in the flushing of the toilet such that when the toilet is flushed and the flush control unit has received the standard flush signal, a standard amount of water is used, otherwise, a reduced amount of water is used.
