1. A water treatment and storage system comprising:
a water treatment flow path including a primary water treatment flow path to receive water from a water source and direct the water in a recirculation flow path to a storage reservoir;
one or more pumping devices to flow the water along the water treatment flow path to the storage reservoir;
a first oxidation unit to inject an oxidizing compound into the water flowing in the primary water treatment flow path;
an additive unit for adding one or more additives into the water flowing in the water treatment flow path in advance of the storage reservoir;
an outbound flow path to receive the water from a reservoir outlet of the storage reservoir and direct the water to a dispensing outlet; and
a controller to control an operation of the water treatment and storage system in a plurality of modes including:
a primary water treatment mode wherein the water is directed through the primary water treatment flow path and a through portion of the recirculation flow path in advance of the storage reservoir;
a recirculation maintenance mode wherein the water is directed from the storage reservoir, through the recirculation flow path and back to the storage reservoir; and,
a mixed water treatment mode wherein the water is directed through the primary water treatment flow path to a portion of the recirculation flow path in advance of the storage reservoir, and wherein the water is directed from the storage reservoir through the recirculation flow path;
wherein the oxidizing compound is ozone,
wherein the controller is configured to maintain at least one of:
an ozone CT value in a first range of 0.2 to 5.5 as a function of temperature in a second range of 50 degrees Celsius to 5 degrees Celsius; and
a concentration of ozone above a concentration value of 0.25 ppm in the water treatment flow path.
