A handwashing valve structure includes a mounting structure, a dispensing structure, and a control structure. The mounting structure is configured to attach to a liquid vessel. The dispensing structure is configured to dispense a liquid from the liquid vessel and is movable between a closed position and an open position. The control structure is configured to move the dispensing structure between the closed position and the open position. The control structure is configured to be moved by pressure from a portion of a user's body to move the dispensing structure from the closed position to the open position. The dispensing structure is configured to automatically move from the open position to the closed position in the absence of any pressure from the portion of the user's body onto the control structure.

A portable campground sink. The portable campground sink includes a frame having at least one sidewall, wherein an interior portion of the frame is divided into a first section and a second section by a cross bar. A plurality of legs are removably affixed to the frame, wherein the plurality of legs extend perpendicularly away from the frame. A container having an upper compartment in liquid communication with a lower compartment is received by the frame such that the lower compartment lies within the first section. An outlet is disposed on the lower compartment can receive a hose thereon. An adaptor having an inlet that can receive the hose thereon can be removably secured within a sewer drain such that the contents of the lower compartment exit through the outlet, through the hose, into the inlet, and out of the adaptor into the sewer drain.
