A recreational vehicle waste delivery system with lengths of 3D cylindrical non-flexible tube and of 3D cylindrical flexible-tube, a first-coupler and, a second-coupler. The first coupler, the at least one flexible-tube, the second-coupler and the at least one flexible-tube in combination are able to be removably couplable modularly in series to provide an adjustable, modular waste management system for delivering waste from an rv to an in-ground sewer connection when engaged with a disposal fitting of the rv.

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 waste tank assembly includes: a tank having a top end configured to be connected, in use, to receive waste via one or more ports, and an open bottom end, the tank defining an interior; a waste cartridge removably received in the tank interior and having one or more ports configured to be fluidly connected to the one or more ports of the tank to receive the waste in an interior volume of the cartridge; and a closure part for securing the waste cartridge inside the tank interior, the closure part openable to allow removal of the cartridge from the tank interior via the open end.

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 RV holding tank disposal system for disposing of waste more quickly, cleaner and more sanitarily. The RV holding tank disposal system includes a duct assembly including a first pipe with inlet and outlet ends and a bore extending therethrough, a second pipe with an open first end, a second end, and a bore extending therethrough with the second pipe in operable communication with the first pipe, and a flexible hose with open first and second ends and a bore extending therethrough with the flexible hose fastened at the inlet end of the first pipe; a holding tank connector assembly connected to the duct assembly and adapted to be removably connected to a RV sewage holding tank; and a sewer adapter attachable to the duct assembly and adapted to be removably disposed in a sewer inlet.

A septic drainage system includes a vehicle that has a septic tank and the septic tank has an outlet. A hose is selectively fluidly coupled to the outlet. Thus, the hose may drain the septic tank. The hose has a distal end with respect to the outlet. The distal end may be fluidly coupled to an inlet of a sewer thereby facilitating the septic tank to drain into the sewer. A supporting unit is provided and the supporting unit may be positioned on a support surface. The hose is positioned on the supporting unit such that the hose is inhibited from becoming uncoupled from the outlet and the sewer. Thus, the supporting unit enhances draining the septic tank.

A waste disposal apparatus for servicing a lavatory of an aircraft. The waste disposal apparatus includes an open-top waste receptacle for accidental fallout of a waste debris or a chemical solution from the aircraft. The waste receptacle includes a plurality of sidewalls that are joined to and extend upwardly from a floor. The floor and the plurality of sidewalls together form a bounds of a workspace within an interior of the waste disposal apparatus. The waste disposal apparatus also includes a plurality of hose ports disposed within the plurality of sidewalls of the waste receptacle. The hose ports include a waste hose port configured to facilitate a transport of waste from the aircraft and a rinse/refill hose port configured to facilitate a transport of a chemical solution to the aircraft. A waste disposal system and a method of servicing an aircraft are also provided.

Systems and methods for bypassing a black tank, for example, in recreational vehicles are provided. A bypass valve of the system is connected to a toilet via a flange and configured to operate in a first position and a second position based on a user input. A bypass line of the system is coupled to the bypass valve at the first position and configured to transfer waste from the toilet to an exit point, bypassing a black tank based on the system being operated in a first operating mode, e.g., bypass mode. A non-bypass line of the system is coupled to the bypass valve at the second position and configured to transfer the waste from the toilet to the black tank based on the system being operated in a second operating mode, e.g., conventional mode.
