Abstract: A waste fluid containment and draining system may have a black waste water holding structure for holding black waste water and a grey waste water holding structure for holding grey waste water. First and second valves may be included for enabling selective emptying of the two holding structures. A macerator pump may be used which has an input in flow communication with both of the first and second valves. A discharge conduit may be in flow communication with an output of the macerator pump. A control subsystem may be in communication with the first and second valves and the macerator pump for controlling the first and second valves, together with the macerator pump, to enable selective pumping out of the holding structures by the macerator pump through the discharge conduit.

Abstract: A flush toilet assembly includes a bowl assembly defining a bowl and a base supporting the bowl assembly. One of the bowl assembly and the base may include a male coupling element and the other may include a cooperating female coupling element. A flush lever may be interconnected to the base for movement between first and second positions and may include a cam surface. A water valve may include a cam follower associated with the cam surface and may be moveable from a closed to an open position through cooperative engagement of the cam surface and cam follower in response to movement of the flush lever from the first to the second position. The base may integrally define a flush water path extending between an inlet port and an outlet port. The water valve may be disposed within a recess defined by the base which intersects the flush water path.

Abstract: A flush toilet assembly includes a bowl assembly defining a bowl and a base supporting the bowl assembly. One of the bowl assembly and the base may include at least one male coupling element and the other of the bowl assembly and the base may include at least one cooperating female coupling element. A flush lever may be interconnected to the base for movement between a first position and a second position. The flush lever may include a cam surface. A water valve may be carried to the base and include a cam follower associated with the cam surface of the flush lever. The water valve may be moveable from a water valve closed position to a water valve open position through cooperative engagement of the cam surface and cam follower in response to movement of the flush lever from the first position to the second position. The base may integrally define a flush water path extending between an inlet port and an outlet port.

Abstract: A self-contained sanitary system includes a stand alone bench carrying a toilet with a flush tank for storing a source of flush water. The system further includes a holding tank. The holding tank is removably associated with the toilet and includes a pair of wheels and a retractable handle.
