Abstract
A system and method are provided for treating liquids in a dispensing reservoir. An ultraviolet source is located in a liquid dispensing reservoir or well. The ultraviolet source discharges ultraviolet light rays in the dispensing reservoir to treat the liquid by killing bacteria in the liquid. One or more existing or added baffle means prevent the ultraviolet light rays from being emitted outside of the dispensing reservoir. The ultraviolet source comprises a waterproof submersible element, with a transformer and a ground fault interrupter breaker typically located outside the reservoir.
