Abstract

A portable hand-washing station that is self-contained to provide hot and cold water to a user as well as dispose of said water. The station includes a rolling hand truck, a sink assembly, a fresh-water tank, a grey-water tank, a water heater, and a water pump. The rolling hand truck includes a base platform and a vertical frame for support. The sink assembly is perpendicularly mounted to the vertical frame, opposite to the base frame. The grey-water tank and the fresh-water tank are positioned in between the sink assembly and the base platform and each are adjacently attached to the rolling hand truck. The grey-water tank and the fresh-water tank are in fluid communication with the sink assembly through the water pump and the water heater to provide the user with clean water. Additionally, a drain of the sink assembly is in fluid communication with the grey-water tank for disposal.
