A waste disposal system for a recreational vehicle characterized by a grey water holding tank and a black water holding tank, wherein the grey water holding tank is positioned at a level above that of the black water tank, the system including means for flushing the contents of said black water tank, comprising:
- grey water outlet means for emptying the contents of said grey water tank into said black water tank via gravity force without passing through a vehicle toilet, said outlet means comprising a valve controllable by the vehicle operator;
- and
- an outlet from said black water holding tank for selectively emptying the contents of said black water holding tank, said contents including grey water admitted via said valve, thereby flushing the black water tank with said grey water as the contents of the black water holding tank are drained.
A recreational vehicle with a waste water disposal system, comprising:
- a grey water holding tank for collecting grey waste water;
- a black water holding tank for collecting black waste water;
- a grey and black water disposal system for flushing said black water holding tank, comprising
- means for emptying the contents of said grey water tank into said black water tank without passing through a vehicle toilet;
- and
- means for draining the contents of said black water tank, including said grey water, into a collection apparatus,
- wherein the flow of said grey water through said black water tank helps to flush solids from said black water tank when disposing of said grey and black water.
In a vehicle characterized by a grey water holding tank and a black water holding tank, a method of flushing the black water tank, comprising a sequence of the following steps:
- opening an outlet from the black water holding tank to empty by gravity the contents of said black water holding tank through said outlet;
