Abstract: 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).
