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.

A bathroom for two cabins of a ship is provided, the bathroom including three spaces and two separate entrances for access to the bathroom from the two cabins. The three spaces include a first room, a second room, and a shower room that is accessible from the first room and from the second room. The shower room includes a movable wall, which is movable between two positions: (i) a first position in which the movable wall forms a separation wall between the first room and the shower room and allows access to the shower room from the second room, and (ii) a second position in which the movable wall forms a separation wall between the second room and the shower room and allows access to the shower room from the first room.

A pump features a liquid sensing device (LSD) in combination with a housing. The LSD senses the level of a liquid collecting outside the pump and turns the pump on/off for pumping the liquid. The housing includes a housing wall to contain the LSD. The housing wall has an outside wall surface with an outside sensing surface. The housing includes an inside mounting structure to mount the LSD inside the housing in relation to the outside sensing surface. The outside sensing surface has ribs extending or projecting outwardly away from the outside wall surface in order to prevent an object from being stuck on the outside sensing surface, and allow the LSD to sense the level of the liquid collecting outside the pump and touching the outside sensing surface, reducing a malfunction of the pump due to the object contacting the outside sensing surface.

A manual lubrication system for a manual toilet flush pump on a manual toilet of the type used in boats and RV's. The lubrication system comprises a lubricant reservoir affixed in parallel to the housing of the manual toilet flush pump laterally opposite the toilet, with a movable lubricant pump head located below the operating handle of the manual toilet flush pump and having an operating axis generally parallel to the that of the manual toilet flush pump's operating handle. A positive manual shutoff normally keeps the lubricant reservoir isolated from the normal in-flow of water to and through the manual toilet flush pump except when lubricant is being manually added during a maintenance procedure.

A urinal for a boat includes an outer shell that has an enlarged opening for accepting liquids (e.g. urine) and a drain. The drain is interfaced to an opening on a bottom surface of the outer shell for draining the liquids away from the boat. In some embodiments, there is a support unit for installing the urinal into an orifice (e.g. fishing pole holder) of the boat.
