Aspects of the present disclosure provide waste containers for waste management on a vehicle, such as a watercraft. A waste container for use on a vehicle may include at least one wall comprising an inner surface defining a chamber for holding waste, and a plurality of projections projecting from the inner surface of the at least one wall into the chamber. Aspects of the present disclosure also provide valve apparatuses for controlling flow of waste into or out of a waste container. Such a valve apparatus may include a non-dismantlable valve body defining a flow channel for conveying waste, and at least one check valve secured within the flow channel and configured to allow waste to flow from an inlet to an outlet of the flow channel and to prevent waste from flowing from the outlet to the inlet.

An emptying device for a medium line of a vehicle, such as a recreational vehicle, can be connected between a medium tank of the vehicle and the medium line to be emptied. A first non-return valve is arranged in a first connecting line between the medium tank and the medium line to be emptied and permits a flow of the medium from the medium tank into the medium line, but blocks a reverse flow. A second connecting line opens into the first connecting line downstream of the first non-return valve. The second connecting line, for emptying the medium line, can be connected to a pressure medium source and can be acted upon by the pressure medium in order to empty the medium line. There is also described a medium installation of a vehicle and a corresponding vehicle.
