Apparatus for funneling waste into a drum containing four trapezoidal sidewalls. The four trapezoidal sidewalls coupled to form a non-symmetric truncated pyramid having a vertical axis. A drain pipe having a circular cross-section with a vertical axis that is coincident with the axis of the pyramid.

Apparatus for funneling waste into a drum containing four trapezoidal sidewalls. The four trapezoidal sidewalls coupled to form a non-symmetric truncated pyramid having a vertical axis. A drain pipe having a circular cross-section with a vertical axis that is coincident with the axis of the pyramid. The drain pipe has external threads for coupling with a drum. A coupling plate is coupled to the pyramid. Four rectangular sidewalls are coupled to the truncated sidewalls to form an upper extension of the pyramid. Vertically extending supports depend from the apparatus sidewall that has notches to position over the peripheral flange of a drum. A filter is supported within the apparatus.
