1. A vehicle wastewater management drainage system for draining a permanent wastewater holding tank of a vehicle, comprising:
a housing including:
a cylindrical outer wall defining an inlet chamber;
an inner wall below the inlet chamber and extending from an inner surface of the cylindrical outer wall;
an outlet passage extending through the inner wall; and
an inlet for introducing wastewater into the inlet chamber;
a valve capable of sealingly closing the outlet passage, the valve being disposed within the inlet chamber and being capable of axially moving therein;
an outlet seat attached to the inner wall and encircling the outlet passage; and
a valve activation mechanism including a plunger attached to the valve for axially moving the valve within the inlet chamber, and a user control member;
wherein the valve activation mechanism is capable of moving the valve from a first position where the valve is spaced from the outlet seat and fluid may flow through the outlet passage, to a second position where the valve sealingly engages the outlet seat and fluid may not flow through the outlet passage.
