A solar electric pump-out boat for removing human waste. The pump-out boat may include a boat hull, wherein the boat hull may include a bow, a stern, and a self-draining sole disposed therein. The pump-out boat may further include a holding tank disposed within the hull underneath the self-draining sole for collecting waste. The pump-out boat may further include a console disposed approximately center of, and on a top surface of the self-draining sole. The pump-out boat may further include a solar panel for absorbing sunlight to convert into electrical power. The pump-out boat may further include a pump disposed within the console. The pump-out boat may further include a battery connected to a motor, the pump, and the solar panel, such that the solar panel charges the battery to provide the electrical power to operate the pump and the motor.

Some embodiments of the invention include a filter for a waste tank, the filter including a housing with a pair of end fittings; an inner tube positioned within the housing, the inner tube having perforated walls; and a negatively charged resin positioned between the housing and the inner tube. The first end fitting may be configured to attach to the tank's vent line, and the second end fitting may be configured to attach to external venting tubes such that fumes from the waste tank are configured to flow from the waste tank, through the inner tube of the filter, and away from the waste tank.

A marine vessel includes pipes and tubular fluid conduits which are a part of a waste water management system. The waste water management system includes CPVC piping that is used to transport at least one of black water or gray water. The CPVC piping meets at least one fire endurance test set forth by the International Maritime Organization. Additionally, or alternatively, the CPVC piping meets at least one test set forth in IMO A.653 (16).

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.
