A water station, or cabinet, or console, particularly for use in kitchens and in restaurant kitchens and in oriental restaurant kitchens, contains (i) a reverse osmosis system, and (ii) a sink. The water cabinet dispenses copious amounts of (i) water purified by reverse osmosis ("RO water"), as well as (ii) tap, or supply, water and (iii) waste water from the reverse osmosis (RO) process, respectively from three faucets in position over the sink. The cabinet is compact: it fits within the footprint of, and replaces, a conventional restaurant sink. The RO water purification performed by the RO system completely within the cabinet is water-conserving, typically producing RO purified water and waste water at a ratio as low as one-to one (1:1) by using an adjustable feedback path for waste water. Operational status is clearly visible. Maintenance is easy, with sediment filters replaceable on-line. RO purified water is supplied to external devices, including "rice robots" and auxiliary purified water storage tanks, by plumbed connections.

[ What is claimed is:] [11.] A kitchen water station, receiving supply water, comprising:a cabinet;a reverse osmosis membrane, contained within the cabinet and flow connected to the supply water, for producing water that is purified by process of reverse osmosis from received supply water;an atmospheric storage tank, contained within the cabinet and flow connected to the reverse osmosis membrane, for storing purified water at atmospheric pressure;a delivery pump, contained within the cabinet and flow connected to the atmospheric storage tank, for pressurizing purified water received from the atmospheric storage tank;an auxiliary storage tank, external to the cabinet and flow connected to the delivery pump, for storing purified water under pressure; anda faucet, mounted to the cabinet, flow connected to the atmospheric storage tank through the delivery pump, and also directly flow connected to the auxiliary storage tank, for dispensing purified water under pressure;wherein storage of purified water transpires both (i) within the cabinet in the atmospheric storage tank at atmosphere pressure, and (ii) external to the cabinet in the auxiliary storage tank under pressure. [12.] The kitchen water station according to claim 11 further comprising:a lower level switch within the atmospheric storage tank for producing a "not-empty" signal when a level of purified water within the tank is more than a predetermined minimum level;a pressure switch within the flow connection between, on a one side, the delivery pump and, on the other side as two items flow-connected in parallel, the faucet and the auxiliary storage tank, for producing a "not-fully-pressurized" signal when a pressure of purified water within the flow connection is less than a predetermined maximum pressure;means for controlling the delivery pump to pressurize purified water from the atmospheric storage tank whenever the pressure switch indicates not-fully-pressurized" and the lower level switch indicates "not-empty";wherein the delivery pump will be controlled to pressurize purified water from the atmospheric storage tank whenever (i) the storage tank is "not-empty", and (ii) either the faucet is open, the auxiliary storage tank is not at the predetermined maximum pressure, or both the faucet is open and the auxiliary storage tank is not at the predetermined maximum pressure, which does cause the flow connection to be "not-fully-pressurized".
