A sewage hose covering device for shielding a sewage hose of a recreational vehicle from view includes a tube, which is sized so that a sewage hose extending from a recreational vehicle is insertable thereinto. The sewage hose is engaged to an inground sewer connection to direct sewage from the recreational vehicle to an inground sewer. The tube is shields the sewage hose from view.

A recreational vehicle includes an exterior side having an elongated strip extending from near the front of the vehicle towards the rear of the vehicle. A utility hook-up compartment in the exterior side includes a compartment door manually opened and closed to uncover and cover utility hook-up compartment, accessing the hook-up compartment upon manually opening the door and preventing access and concealing the hook-up compartment upon manually closing the door. The strip has first and second portions with exterior surfaces that provide a visual camouflage effect, hiding within the unitized strip itself the hook-up compartment door upon closure thereof and alignment of both portions. Door closure brings the first and second portions into alignment along a common longitudinal reference line to form an integrated unit.

The present invention provides a waste disposal apparatus for assisting in the disposal of waste from an aircraft and replenishment of sanitary chemical solutions to the aircraft during servicing of a variety of aircraft lavatories. The waste disposal apparatus features, among other parts, a waste receptacle, a face shield, multiple interface inserts, a waste hose port, a rinse/refill hose port, an electric wire port, a drain port, and, optionally, one or more add-on tanks. Further, the waste disposal apparatus can be used in conjunction with various types of stands which can be adapted to existing aircraft service vehicles. Through the use of the waste disposal apparatus, the ramp attendant, the aircraft ramp, the tarmac, customer baggage, and other property on the ramp are protected from contamination with human waste and chemical solutions used to deodorize and sanitize aircraft lavatories.

A sanitation assembly for sanitation of terminals of wastewater discharging pipes includes a sanitation chamber inside which, while in use, there is located a terminal to be sanitized. A fixed UV emission means is located inside the sanitation chamber near a bottom portion thereof and arranged to emit a UV radiation upwards, the fixed UV emission means including a first plurality of LEDs arranged along a first circumference and a second plurality of LEDs arranged along a second circumference inside said first circumference, the first and the second plurality of LEDs being arranged to emit upward a UV radiation having a wavelength ranging from 200 and 300 nm. A movable UV emission means is housed inside the sanitation chamber and includes a third plurality of LEDs designed to emit a radiation ranging from 200 and 300 nm and arranged along a circumference on a vertically moving ring-shaped structure which, while in use, is arranged to surround the terminal to be subject to sanitation. The LEDs of the third plurality of LEDs are designed to emit, in a converging manner, a UV radiation having the wavelength ranging from 200 to 300 nm.

An extraction device for discharging a mixed fluid, in particular containing feces, from a collecting tank of a rail vehicle comprises a housing having a mixed fluid inlet and a mixed fluid outlet, a flow passage which extends in the housing between the inlet and the outlet, a retaining latch mounted to the housing and adapted to cooperate with a corresponding recess on the collecting tank and is pivotably reciprocal between a locked position and an unlocked position, a shut-off member reciprocable between a release position and a blocking position, and a handling means or actuator mounted to the housing for actuation of the shut-off member. The handling means is operatively connected to the retaining latch in such a way that upon the movement of the retaining latch into the unlocked position the shut-off member is put into the blocking position.

This invention relates to a disposable sewer hose liner that may be used to line the inside of a sewer hose for recreational vehicles, trailers, and mobile homes. The disposable sewer hose liner provides a more sanitary method of disposing sewage and waste water from an RV, trailer, or mobile home and reduces the odor emanating from a sewer hose, the amount of cleaning necessary, and the amount of bacteria or waste that a user comes in contact with when interacting with a sewer hose.

A hose stand assembly includes a plurality of rings that is each positionable around a fuel hose. A plurality of legs is each of the legs is pivotally disposed on a respective one of the first portion and the second portion of a respective one of the rings. Each of the legs is positionable in a deployed position having each of the legs extending downwardly from the respective ring. In this way each of the legs can support the respective ring above a support surface. Thus, the rings and the legs support the fuel hose above the support surface when the fuel hose is extended through the respective ring. Moreover, each of the legs associated with each of the rings has a unique length with respect to each other to orient the fuel hose at a downward slope for enhancing the flow of fuel in the fuel hose.

A sewage discharge device detachably and hermetically connected to a sewage tank includes a drain pipe and a main box body. A drain control valve and a self-priming drain pump are provided inside the main box body. One end of the drain control valve is detachably and hermetically connected to the drain pipe. The other end of the drain control valve is detachably and hermetically connected to the self-priming drain pump. The self-priming drain pump is provided with a drain nozzle and a cleaning coupling. The drain nozzle is detachably and hermetically connected to a sewage pipe. The drain nozzle and the cleaning coupling protrude outside the main box body. The sewage discharge device of the present invention prevents users from contacting fecal matter and wastewater. Manual cleaning of the drain pipe is also eliminated, which is convenient to use.

An RV sewage drain hose hanger that may be mounted to an RV or at a suitable location at an RV sewage dump station is disclosed. The apparatus includes an attachment point for the inboard end of the RV drain hose. When the drain hose is connected to the attachment point the hose is retained in a substantially vertical orientation with the open end of the drain hose facing upwardly. Located above the drain hose attachment is a hose support connection that supports a standard garden hose above the sewage drain hose so that the nozzle of the hose is directed downwardly into the open end of the drain hose. The hose support may be defined by a first and optional second platform, each having an opening for the hose. The flow of water from the hose nozzle is aimed directly into the open end of the sewage drain hose.
