The apparatus of claim 1, wherein the chilled water line comprises a flow compensator configured to receive water from an outlet of the carbonator, modify the flow, and direct the flow towards the chilled water line outlet. 9. The apparatus of claim 1, wherein the carbonator comprises: a conduit;an inlet to a flow path on the proximal end of the conduit;one or more dispersion elements arranged within the conduit;a passive accelerator within the conduit;a rigid impact surface immediately downstream of the passive accelerator; anda retention network connected to the distal end of the conduit. 10. The apparatus of claim 1, wherein the carbonator comprises: a conduit;an inlet for directing carbon dioxide and water into the conduit;a rigid surface within the conduit; anda restriction within the conduit for accelerating the carbon dioxide and water to a speed sufficient such that when the carbon dioxide and water collide with the rigid surface they create an energy density sufficient to solubilize carbon dioxide in water. 11. The apparatus of claim 1, further comprising a filter. 12. The apparatus of claim 11, wherein the filter is arranged such that all water passing from the main inlet to each of the chilled water line, unchilled water line, and hot water line passes through the filter. 13. The apparatus of claim 3, wherein the heater is configured to heat water in the hot water line to a temperature of 85 C or more. 14. The apparatus of claim 1, wherein the controller is configured to modulate the state of the gas inlet valve while the apparatus is dispensing carbonated water to adjust a carbonation level of the dispensed carbonated water. 15. An apparatus for dispensing water comprising: a dispenser integrated in a refrigerator, the dispenser comprising: a main inlet configured to receive water from a source;a chilled water line, comprising: an in-line carbonator;a carbonator water inlet valve configured to selectively direct water from the main inlet to the carbonator;a carbonator gas inlet valve configured to selectively direct carbonating gas to the carbonator; anda chilled water line outlet;a heat exchanger configured to chill water passing through the chilled water dispensing line, wherein the heat exchanger comprises a cooling tank configured to receive water from the main inlet and at least a portion of the chilled water line is immersed in the cooling tank;a controller configured to control the carbonator water and gas inlet valves;a cooling tank fill sensor in communication with the controller and configured to generate information indicative of a fill level of the cooling tank; anda cooling tank fill valve controlled by the controller and configured to selectively direct water from the main inlet to the cooling tank;wherein:when the carbonator water inlet valve is open and the carbonator gas inlet valve is closed, the chilled water line dispenses still water at the chilled water line outlet;when the carbonator water inlet valve is open and the carbonator gas inlet valve is open, the chilled water line dispenses carbonated water at the chilled water line outlet; andthe controller is configured to control the operation of the cooling tank fill valve based on the information indicative of a fill level of the cooling tank. 16. The apparatus of claim 15, further comprising: an unchilled water line comprising:an unchilled water inlet valve configured to selectively direct water from the main inlet to an unchilled water line outlet;wherein the unchilled water inlet valve is controlled by the controller. 17.
