WASTE FLUID HOLDING TANK DRAIN SYSTEM AND METHOD

摘要

A waste fluid containment and draining system may have a black waste water holding structure for holding black waste water and a grey waste water holding structure for holding grey waste water. First and second valves may be included for enabling selective emptying of the two holding structures. A macerator pump may be used which has an input in flow communication with both of the first and second valves. A discharge conduit may be in flow communication with an output of the macerator pump. A control subsystem may be in communication with the first and second valves and the macerator pump for controlling the first and second valves, together with the macerator pump, to enable selective pumping out of the holding structures by the macerator pump through the discharge conduit.

1. A waste fluid containment and draining system comprising:
a black waste water holding structure for holding black waste water; a grey waste water holding structure for holding grey waste water; a first valve associated with the black waste water holding structure enabling emptying of the black waste water when the first valve is opened; a second valve associated with the grey waste water holding structure enabling emptying of the grey waste water when the second valve is opened; a macerator pump having an input in flow communication with both of the first and second valves; a discharge conduit in flow communication with an output of the macerator pump; and a control subsystem in communication with the first and second valves and the macerator pump for controlling the first and second valves, together with the macerator pump, to enable operation of the macerator pump and selective pumping out of the holding structures through the discharge conduit.
