Abstract:
1. A hand-wash sink station comprising: a used water storage tank; a fresh water tank disposed adjacent to the used water storage tank; at least one wash basin disposed above the used water storage tank; a fresh water supply faucet arranged in proximity to each wash basin and with the faucet connected to the fresh water tank for providing fresh water to each wash basin when desired; a wash basin drain connection between the used water storage tank and each wash basin for draining used water from each wash basin into the used water storage tank; and a tube arranged adjacent to the used water storage tank, the tube having one open end opening into a lower end of the used water storage tank to form an inlet, an intermediate section disposed at a height above a highest anticipated level of used water in the used water storage tank, and a second open end forming an outlet, opening to the outside of the sink station for draining water therethrough; whereby, the height of the tube is operable to prevent used water from draining through the tube and out of the used water storage tank without the application of suction to the tube to provide a siphon action for causing the used water to flow through and out of the tube; and whereby used water may be siphoned from the used water storage tank upwardly through the intermediate section of the tube to the outlet of the tube when a vacuum is applied to the tube outlet.
