Liquid waste evacuation and transfer system

An apparatus for evacuating and transferring liquid waste comprising a pump assembly that is connected to a holding tank and to a fluid container, said pump assembly adapted to remove said liquid waste from said container and transferring said liquid waste to said holding tank, said pump assembly being mounted on a wall and being elevated above said holding tank so that said liquid waste is partially transferred into said holding tank by gravity, said pump assembly including a flexible hose that extends from said assembly and is attached to said container, said container including a drain pipe and a suction pipe therein, said drain pipe and said suction pipe including at least one slit in the bottom thereof to inhibit air build-up therein.

An apparatus for evacuating and transferring liquid waste comprising a pump assembly that is connected between a holding tank and a liquid waste container for transferring said liquid waste from said container to said holding tank, said pump assembly including:

• pump mechanism means having an intake means and an output means, said output means connected to said holding tank at a point above said holding tank to provide a gravity assist to the fluid being transferred to said holding tank, pump intake means including flexible hosing means adapted to be removably attached to said liquid waste container;
• said liquid waste container including pipe means therein extending to the bottom of said container, said pipe means including a drain pipe and a suction pipe having inhibiting means at the lower end thereof to prevent air from being drawn into said drain pipe and said suction pipe when said pump assembly is operative.

A method for evacuating and transferring liquid waste comprising a pump assembly mounted on a wall and connected to a holding tank and to a liquid waste container, comprising the steps of:

• evacuating said liquid waste from said container through a suction means which includes a drain pipe and a suction pipe and which are located in said container, pumping said liquid waste through said drain pipe and said suction pipe and a flexible hose attached to said pump assembly and said drain pipe and said suction pipe, said liquid waste passing through said flexible hose and into an intake side of said pump assembly and exiting from an output side of said pump assembly disposed above the level of said holding tank, said liquid waste being eventually discharged from said output side of said pump assembly into said holding tank partially by gravity and partially by the force of said pump assembly.
