Abstract
A macerator/ejector pump within a waste material holding tank on a boat liquefies solid waste material in the tank and pumps the liquefied waste material through a discharge line adapted for connection to an on-shore waste collection system. The macerator/ejector pump comprises a pump and a plurality of cutter blades pitched to direct the liquefied waste to the intake port of the pump, the pump and the cutter blades being driven by a shaft connected to an electric motor mounted on the top of the holding tank. The holding tank may be discharged into the on-shore waste collection system without requiring a shore-based pump-out station. A plurality of rods extend into the holding tank for sensing the level of waste material, and a holding tank monitor displays this level by means of colored indicator lamps.
