Abstract
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 …
