1. A method of sanitizing drinking water dispensed from a water dispenser having a water supply that includes an inverted bottle and neck supported upon a cabinet so that the neck extends downwardly, an anti-spill receiver having a projecting probe that extends into the bottle neck, and a reservoir having a bottom and a water surface, comprising the steps of:

  • a) providing an ozone gas generator that generates a mixture of air and ozone gas;

    b) providing a first flow line that carries the mixture;

    c) transmitting the gas mixture from the generator to the water dispenser reservoir via the first flow line;

    d) creating, in the reservoir, a stream containing water from the reservoir and gas bubbles containing the gas mixture transmitted from the first flow line;

    e) directing a first portion of said stream to disinfect the water in the reservoir;

    f) providing a second flow line in the reservoir; and

    g) discharging a second portion of said stream at a position that is closer to the water surface than to the bottom of the reservoir and within the anti-spill receiver with the second flow line.
