Patent ID: 7311817

Claim:
A system for sanitizing and refilling a potable water system onboard a transport vehicle, comprising: a potable water supply conduit extending from a public water supply to a potable water sanitizing and refilling station; a potable water feed conduit extending from the sanitizing and refilling station to the transport's potable water system; a potable water return conduit extending from the transport's potable water system to the sanitizing and refilling station; a drain conduit in fluid communication with the sanitizing and refilling station and the return conduit, respectively; the sanitizing and refilling station including a pump operable for selectively causing water to pass through the sanitizing and refilling station, and also causing water to pass to and from the potable water system onboard the transport vehicle through the feed conduit and the return conduit; and the sanitizing and refilling station also including an ozone generator and injector for selectively injecting ozone into water passing through the sanitizing and refilling station and water passing to and from the transport's potable water system through the feed conduit and the return conduit; the system being operable in a self-flush mode, a sanitizing mode, and a fill mode, wherein: in the self-flush mode the system operates for a preselected or preset time to purge stagnant water from the sanitizing and refilling station; in the sanitizing mode the system operates for a time sufficient to achieve sanitization of the transport's potable water system; and in the fill mode the system operates for a time sufficient to substantially refill the transport's potable water system.
