Claim 0:
1. An operating assembly for use with a sink or bathtub having at least one fluid-holding basin and a basin drain, comprising:
an actuator;
a housing, the housing comprising:
a plug structure at, or near, a bottom portion of the housing for selectively blocking the basin drain;
a drain valve comprising an inlet adjacent a bottom portion of the housing controlled by the actuator to be in an open position or a closed position, wherein the inlet of the drain valve is provided on a first side of the housing, and wherein an outlet of the drain valve is provided on a second side of the housing opposite the first side and directs fluid into the plug structure;
wherein the plug structure mates with the basin drain to prevent fluid in the at least one fluid-holding basin from escaping into the drain other than through the drain valve; and
wherein, when the drain valve is in the open position, fluid in the at least one fluid-holding basin is able to flow through the drain valve into the basin drain and, when the drain valve is in the closed position, fluid in the at least one fluid-holding basin is unable to flow through the valve into the basin drain; and

a processor configured to send commands for controlling the actuator, such that in response to the commands from the processor, the actuator opens or closes the drain valve such that the operating assembly is capable of automatically draining the at least one fluid-holding basin;
wherein the processor is in communication with a water valve operable between open and closed conditions to selectively deliver water to the at least one fluid-holding basin; and wherein the processor is configured to:
receive input from a temperature sensor, a cleanliness sensor, and a liquid level sensor; and
send commands for controlling the actuator and the water valve such that in response to the commands from the processor, the actuator is configured to open or close the drain valve and the water valve is capable of opening or closing such that the operating assembly is capable of automatically filling and draining the at least one fluid-holding basin to maintain a desired range of concentrations of a fluid comprising one or more of water, soap, and sanitizer, and to maintain the fluid in one of the at least one fluid-holding basins at a desired amount or height and within a desired range of temperature.
