A lid having an outlet is provided for covering the top of the container. A hose is connected to the lid outlet and to a vacuum blower. A lid conduit forming the lid outlet extends through the lid with inlet openings formed through the lower portion of the outlet conduit. A chamber extends from the lower side of the lid surrounding the lower portion of the lid conduit with a bottom wall located below the lower portion of the lid conduit. A plate is connected to the bottom of the lid conduit and extends outward forming a dead space between the plate and the bottom wall of the chamber. An opening is formed through the side wall of the chamber for passage of air from the container into the chamber and to the vacuum device. The dead space is employed to keep water from passing to the vacuum blower.
