A hospital faucet assembly (10) is provided that includes an outlet (20) adapted to direct a flow of water (24) stream into a sink (12). An ozone chamber (30) is provided having a water inlet (40) and a water outlet (42). A flow control valve (52) is connected to the water inlet (40), and the water outlet (42) is connected to the faucet armature (20). A sensor (60) is provided which is adapted to control the flow control valve (52). An ozone generator (66) is located within the chamber (30), and when a user activates the sensor (60), the valve (52) opens allowing more water to enter the chamber (30) and then travel out through the water outlet (42) of the ozone chamber (30) to the faucet armature (20) which dispenses the water flow (24) into the sink (12). A controller (50) is provided and is connected to the control valve (52) and the sensor (60). The controller (50) is configured to run an automatic cycle on an occasional basis to flush the sink (12) with ozone-rich water in order to flush and/or disinfect water located in a trap (18) of the sink drain (16), or provide other disinfecting functions.
