A water purification method and system, wherein a source of ultraviolet light is disposed relative to the vessel containing the water to be purified for directing ultraviolet light along a major axis of the vessel, and the water is illuminated with the ultraviolet light. One of the systems includes a vessel containing the water to be purified, at least one ultraviolet lamp, external to the vessel, and at least one collimaor for collimating ultraviolet light radiated by the at least one lamp, wherein the light illuminates the water along a major axis of the vessel, Preferably, the lamp can be operated in one or more of the following three modes: continuous constant intensity; quasi cw intensity; and/or pulsed intensity.
