Dump facility for cassette sewage tanks

A method of dumping sewage from an RV tank having an outlet and containing sewage using a container having an outlet hose and an open or openable position, comprising substantially sequentially:

• (a) inserting the tank into the container through the open or openable position;
• (b) effecting a substantially liquid-tight seal between the tank outlet and the container outlet hose;
• (c) mechanically rotating the container about a substantially horizontal axis so as to cause sewage in the tank to flow through the outlet hose, out of the tank, to substantially empty the tank;
• (d) mechanically rotating the container about the substantially horizontal axis back to a position for ready tank withdrawal;
• and
• (e) withdrawing the tank from the container through the open or openable position.

A dump station for RV sewage-containing tanks having an outlet, comprising:

• a cabinet having an open front end which may be closed by a movable door;
• disposed within said cabinet a container which can receive an RV sewage-containing tank, said container having an open or openable front end, a rear end to which an outlet hose is operatively connected, a bottom having tracks for receipt of an RV sewage-containing tank, and a stop for stopping penetration of the tank into said container;
• said container mounted for rotation about a generally horizontally axis from a first position in which said rear wall is generally vertical, to a second position in which said rear wall is generally horizontal and sewage can flow out of said tank disposed within said container through said outlet hose;
• and
• a spray head operatively connected to said rear wall of said container for spraying a cleaning liquid into a tank received by said container.
