A handwash station comprises a wall mounted cabinet which contains soap and water dispensing means, a proximity sensor and processing circuitry. The processing circuitry controls the dispensing of soap and water in response to signals from the proximity sensor. A count of valid handwashes is incremented only if a user's hand is detected by the proximity sensor at certain key points. The key points comprise at least the start of a last soap dispensing step and the start of a last rinsing water dispensing step. Differential valid handwash count values are stored periodically by the processing circuitry and can be downloaded to a central station for analysis.

[ What is claimed is:] [1.] A hand washing and rinsing unit for a wash basin comprising:a water dispenser;a liquid soap dispenser;a proximity sensor for detecting a user's hand or hands in a position to receive soap and/or water from the water and soap dispensers and outputting a hands present signal indicative thereof; anda controller configured so as to cause the unit to operate in a waiting mode and in an active mode,wherein, when the unit is in said waiting mode, the controller is continuously in a state in which it is responsive to the occurrence of a hands present signal to cause:(a) the water dispenser to dispense a quantity of water onto a user's hand or hands for wetting thereof, and(b) enter the unit into said active mode, and,when the unit is in said active mode, the controller:(a) establishes a last soap test window after said dispensing of a quantity of water, and(b) is responsive to the occurrence of a hands present signal in said last soap test window, to cause the soap dispenser to dispense soap onto the user's hand or hands and record a valid handwash event.
