<p>A waste transfer system includes a toilet bowl, a discharge pipe, and a hopper. The hopper is positioned between the toilet bowl and the discharge pipe. A first valve is disposed between the toilet bowl and the hopper. A second valve is disposed between the hopper and the discharge pipe. A source of fluid is in communication with the hopper for pressurizing the hopper to a pre-determined pressure. A method of transferring waste through the waste transfer system includes the step of opening the first valve to permit the passage of waste from the toilet bowl to the hopper and subsequently closing the first valve. The method additionally includes the step of pressurizing the hopper while the first and second valves are closed. The method further includes the step of opening the second valve to thereby force the waste from the hopper into and through the discharge pipe. <IMAGE></p> |
