A dump facility for RV sewage-containing tanks allows the tanks to be emptied in a simple and hygienic manner. A container which can receive a tank includes a connector for making a liquid tight seal with an outlet from the tank when it is received by the container. A flexible conduit is connected to the connector and transports sewage from the tank to a disposal location, and a spray head may be mounted to the connector to spray cleaning liquid into the tank within the container. The container is mounted for movement about a generally horizontal axis between the first position in which a tank may be readily inserted into the container, and a second position in which sewage from the tank may flow by gravity through the connector and the flexible conduit. Rotation of the tank about the axis may be provided manually or by a reversible powered element (such as a motor with associated sprockets and chain). The container is preferably mounted within a cabinet having a roller blind door closing the open front of the cabinet, and access to the door, and/or movement of the container about the axis, may be provided by a conventional token or money activated control.

[ What is claimed is:] [15.] 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.
