An additive sub-system for a wastewater management system of a vehicle including at least one holding tank and a toilet has a controller, at least one additive dispenser and a pump. The at least one additive dispenser is in fluid communication with the at least one holding tank or the toilet. The pump is associated with each additive dispenser of the at least one additive dispensers. Each pump is controlled by the controller to dispense an additive from the at least one additive dispenser to the at least one holding tank or the toilet.

Additive dosing sub-system for a vehicle wastewater management system

An apparatus for delivering wastewater from a recreational vehicle to a drain includes a housing having an outer wall and an inner wall generally perpendicular or slightly angled to the outer wall. The housing and the inner wall define an inlet chamber above the inner wall and a further chamber below the inner wall. The housing further includes an outlet downwardly extending from the inlet chamber.

Discharge device for vehicle wastewater management system

A wastewater management systemincludes a black water tankfor holding black wastewater and a grey water tankfor holding grey wastewater. The systemmay additionally include a filterfor filtering suspended solids from the grey water; a first conduitbetween the grey water tankand the filter; a second conduitbetween the filterand a toilet, and a third conduitbetween the filterand the black water tank, the third conduitassociated with a valve; and a fourth conduitbetween the filterand the grey water tank, the fourth conduitassociated with the valve. The systemfurther includes a control sub-systemin communication with the valvesfor controlling valvesto deliver filtered grey water to the toiletfor flush and to periodically clean the filterof captured solids and deliver the captured solids to the black water tank. A related method for managing wastewater within a recreational vehicles with the wastewater management system, an apparatus for delivering wastewater from a recreational vehicles to a drain and an additive sub-systemfor wastewater management system of a vehicle are also provided. Further, the present teachings relate to a systemincluding a housing associated with a toilet, the housing including a valve and a macerator pumping arrangementincluding a maceratorand a pumpthat work independently from one another, the maceratorincluding a plurality of macerating knivesdriven by a first motor, the pumpproviding positive pressure, the macerator pumping arrangementis operative in a macerating mode and a pumping mode, such that the first motorfirst drives the macerating knivesto macerate the waste and subsequently, the pumppumps the waste out of the housing
