A compact, self-contained, portable vacuum toilet system having a sump for collecting waste liquids by means of gravity, a differential pressure-operated discharge valve for regulating withdrawal of waste liquids from the holding sump for transport to a vacuum collection tank during a transport cycle, differential pressure-operated sensor and controller valves for regulating operation of the discharge valve in response to a hydrostatic pressure condition inside the holding sump, and a push button-operated water valve for adding water to the toilet bowl during and immediately after a flush cycle. A sink and its own push button-operated water valve may also be provided.

Portable vacuum toilet system

An integral, vacuum operated, package system for collecting and transporting waste liquids from, e.g., a defrosted freezer, sink, bathtub, or water fountain, to a vacuum transport conduit connected to a vacuum collection station. The package system preferably includes a collection sump, sensor valve, controller valve, vacuum volume, and vacuum valve, which operatively communicate with each other by means of applied differential pressure to withdraw waste liquid from the collection sump and pass it through an opened vacuum valve during a transport cycle. The package system is compact, portable, and easily installed and maintained, and may be concealed in most applications, since it requires a mere volume generally measuring 12'.times.8'.times.31/2.'
