Abstract: A system for sanitizing a potable water station includes a pair of conduits providing a fluid connection between the potable water station and the system. It also includes a pump operable for circulating water from the potable water station through one of the conduits to the system and through the other of the conduits from the system to the potable water station. Further, the system includes an ozone generator for injecting ozone into the circulating water to destroy bacterial contamination. A method for sanitizing a potable water station includes the step of circulating water from the potable water station and back to the potable water station. It also includes the step of generating ozone with an ozone generator. Further, the method includes the step of injecting ozone into the water circulating from and back to the potable water station.

Abstract: An automatic flushing system for a potable water station includes a conduit having a first end connected to a potable water supply source and a second end having a nozzle coupling. It also includes an air gap assembly having a coupling operable for coupling with the nozzle coupling to releasably connect the conduit to the air gap assembly in a stored position. Further, the system includes a control system operable for automatically flushing potable water through the conduit and the air gap assembly after exceeding a predetermined time in which a predetermined minimum threshold temperature is exceeded and a predetermined time during which the potable water station has remained idle. A method for automatically flushing a potable water station includes the step of providing the potable water station with a conduit having a first end connected to a potable water supply source and having a second end remote therefrom.

Abstract: A system for sanitizing and refilling a potable water system onboard a transport vehicle includes a potable water supply conduit, a potable water feed conduit, a potable water return conduit, a drain conduit, and a sanitizing and refilling station wherein the system is operable in a self-flush mode, a sanitizing mode using ozone, and a fill mode. A method of sanitizing and refilling a potable water system onboard a transport vehicle includes the steps of purging stagnant water from a sanitizing and refilling station, draining stagnant water from the transport's potable water system, sanitizing the transport's potable water system using ozone, draining the transport's potable water system, and filling the transport's potable water system by delivering fresh water.
