The Recreational Vehicle (RV) Black Water Holding Tank By-Pass Piping Apparatus invention is a RV black water holding tank by-pass plumbing system that enables continuous use of the toilets within said RV while docked that is residential plumbing code compliant. Our invention consists of additional “Drain” piping , fittings and gate valves to divert the toilets discharge waste product when flushed around the RV's existing Black Water Holding/Storage Tank directly to the RV's Main Sewer Connection while at the same time maintaining the ability to flush the entire sewer discharge piping/lines with available waste from the RV's gray water storage/holding tanks as highly recommended by all RV manufacturers. This by-pass capability eliminates the need to “Routinely Dump” the normally accumulated black wastewater collected in the black water tank, a procedure that can be required typically every 3 to 5 days and one that can also, by the nature of the waste product being handled, cause severe illness if not performed with caution. Our invention does not require any replacement or reworking of any Original Equipment (RV) Manufacturer's (OEM) provided appliances or apparatus. All required components are external to these devices. Our invention can either be installed as part of the original build at the RV manufacturers manufacturing facility or as an add on or “After Market” addition at any Dealers or RV Equipment Suppliers facility/shop. While our inventions description describes a primarily manually operated system it can optionally include a partially automated wired or wireless automation control system. This invention minimizes the environmental impact of the use of black wastewater holding tank additives/chemicals by avoiding use of the black wastewater holding tank entirely thereby enabling the conservation of chemical additives commonly used by preventing the need to add them.

A holding tank system for holding a waste, the holding tank system including: a holding tank including a floor disposed in a first plane, the holding tank configured to be supported on at least one joist disposed in a second plane, wherein the second plane is disposed at an incline with respect to the first plane.

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.

A mobile bathroom assembly with a support frame member assembly operably configured to attach to a trailer hitch and support a lower shell and an upper shell. The lower shell includes a bottom wall and a sidewall enclosing a lower shell cavity and having a lower sidewall door. The bottom wall includes a toilet assembly coupled thereto fluidly coupled to a liquid supply tank and a circulation pump operably configured to induce a flow of liquid from the liquid supply tank to the toilet assembly. The upper shell also includes a sidewall surrounding a ceiling wall and defining an upper shell cavity, wherein the upper shell is operably configured with a motor assembly to extend upwards and contract downwards with respect to the lower shell to increase and decrease the internal assembly height and lower and upper shell cavities within the lower and upper shells.

An actuation device for a public transport vehicle to avoid transmission of bacteria during the actuation. The device can be actuated by a predefined contactless actuation gesture, the device having a sensor unit that measures without contact and an evaluation unit, which is connected to the sensor unit. The sensor unit can generate a sensor signal transmit the sensor signal to the evaluation unit when an object, in particular a finger or a hand of a person, performs, within a detection space of the sensor unit, a movement at a distance from the actuation device, the signal being dependent on the movement sequence of the movement. The evaluation unit can check whether the movement is a predefined contactless actuation gesture, by which the actuation device can be actuated. If the movement is such an actuation gesture, a control signal is generated for a device of the vehicle.

A wastewater management system 10 includes a black water tank 12 for holding black wastewater and a grey water tank 14 for holding grey wastewater. The system 10 may additionally include a filter 62 for filtering suspended solids from the grey water; a first conduit 64 between the grey water tank 14 and the filter 62; a second conduit 66 between the filter 62 and a toilet 22, and a third conduit 68 between the filter 68 and the black water tank 12, the third conduit 68 associated with a valve 26; and a fourth conduit 69 between the filter 62 and the grey water tank 14, the fourth conduit 69 associated with the valve 26. The system 10 further includes a control sub-system 38 in communication with the valves 26 for controlling valves 26 to deliver filtered grey water to the toilet 22 for flush and to periodically clean the filter 62 of captured solids and deliver the captured solids to the black water tank 12. A related method for managing wastewater within a recreational vehicles with the wastewater management system 10, an apparatus for delivering wastewater from a recreational vehicles to a drain and an additive sub-system 54 for wastewater management system of a vehicle are also provided. Further, the present teachings relate to a system 10 including a housing associated with a toilet 22, the housing including a valve and a macerator pumping arrangement 34 including a macerator 34a and a pump 34b that work independently from one another, the macerator 34a including a plurality of macerating knives 37 driven by a first motor 35a, the pump 34b providing positive pressure, the macerator pumping arrangement 34 is operative in a macerating mode and a pumping mode, such that the first motor 35a first drives the macerating knives 37 to macerate the waste and subsequently, the pump 34b pumps the waste out of the housing 34a.
