ABSTRACT:
A used water removal system for a stand-alone hand-wash sink station having a vertically elongated used water storage tank and within which a vertically elongated, fresh water tank is positioned. A sink basin disposed above the used water storage tank drains used water into the used water storage tank. A water line conveys water from the fresh water tank to a faucet located above the sink basin. An inverted, vertically elongated, U-shaped tube is arranged within the station alongside the fresh water tank. One end of the tube opens into the used water storage tank near its lower end. The second end of the tube opens to the outside of the station. The curved bight of the tube is located at a height that is above the maximum height of the used water within the used water storage tank. Water may be rapidly removed from the tank by temporarily applying suction to the second end of the tube to siphon used water through the tube and out of the used water storage tank.
