A toilet facility for use in boats, campers, mobile homes, recreational vehicles, land and water cruisers, residences, basement flush up, and the like, is disclosed. The toilet facility utilizes a minimum amount of flush water and includes a modified water closet bowl of the siphon type, a sump tank, a macerator pump means, and a water closet tank. A macerator pump means is coupled in fluid communication between a holding tank or other disposal means and the sump tank. The macerator pump is electrically energized through a control circuit when the flush handle is tripped. The duration of the flush cycle may be controlled by a timing circuit which will automatically shut off the macerator pump. Also, the macerator pump may be shut off by the control circuit sensing that the flush cycle is complete, that is, when the macerator pump is pulling only air therethrough or when the control circuit senses the absence of water at the macerator pump inlet. All of the waste and contaminated water is evacuated from the bowl leaving clean, uncontaminated water in the bowl to provide a water seal after the flush cycle is completed and when the toilet facility is not in use. When the macerator pump is in operation, the water is drawn from the bowl through the pump and either into a holding tank or other waste disposal or treatment means.
