A water treatment tank for use with water purification apparatus including an ultra-violet lamp within an encapsulating sleeve onto which incoming water is directed to provide a thin laminar flow about the bulb. The lower compartment has cooling coils about the walls for cooling the water therein relative to the water in the upper compartment. A surrounding sleeve may be located intermediate the encapsulating sleeve and an outer vessel in the tank. A leak detector is located in the encapsulating sleeve. The leak detector and outer vessel are believed to provide safety to users in the event of internal breakage in the tank. A reflective surface is also utilized to direct UV light into portions of the faucets formerly obscured from UV treatment. The faucets preferably provide self-sanitizing capability and an information center selectively displays time until next service, cost savings over bottled water and information related to the dispenser.

What is claimed is: 1. A water dispenser comprising a housing having a water treatment tank, a water inlet selectively feeding water into an upper section of said tank, cooling coils acting to chill water in a lower section of said tank, an ultra-violet lamp disposed in both the upper and lower sections of the tank for transmitting ultra-violet light rays to water in both upper and lower sections to eliminate bacterial growth in both upper and lower sections, an encapsulating sleeve disposed about the ultra-violet lamp providing a water free area about the lamp, a first faucet communicating with said lower section for dispensing chilled water selectively, and a leak detector sensing in the water free area. 2. The water dispenser as recited in claim 1 further comprising a reflective surface located in the upper section of the tank. 3. The water dispenser of claim 2 wherein the reflective surface reflects ultra-violet rays from the lamp into at least a portion of the first faucet. 4. The water dispenser of claim 1 further comprising a solenoid valve in communication with the water inlet wherein when the leak detector detects water in the water free area, the solenoid valve is shut. 5. The water dispenser of claim 1 further comprising an outer vessel disposed in the tank below and around at least a portion of the lamp and encapsulating sleeve. 6. The water dispenser of claim 5 further comprising a surrounding sleeve intermediate the outer vessel and the encapsulating sleeve, said surrounding sleeve spaced to provide an opening intermediate the surrounding sleeve and outer vessel wherein water passes through the opening as it is fed toward the upper section of the tank. 7. The water dispenser as recited in claim 6 further comprising a baffle separating the upper and lower sections of the tank, said baffle connected to the outer vessel. 8. The water dispenser of claim 1 further comprising a translucent baffle separating the upper and lower sections of the tank. 9. A water dispenser comprising a housing having a water treatment tank, a water inlet selectively feeding water into an upper section of said tank, cooling coils acting to chill water in a lower section of said tank, an ultra-violet lamp disposed in both the upper and lower sections of the tank for transmitting ultra-violet light rays to water in both upper and lower sections to eliminate bacterial growth in both upper and lower sections, a first faucet communicating with said lower section for dispensing chilled water selectively, and a reflective surface disposed in an upper portion of the tank reflecting ultra-violet rays into at least a portion of the first faucet. 10. The water dispenser of claim 9 further comprising an encapsulating tube about the ultra-violet lamp, said encapsulating tube providing a water free area about the ultra-violet lamp. 11. The water dispenser of claim 10 further comprising a leak detector sensing in the water free area. 12. A water dispenser comprising a housing having a water treatment tank, a water inlet selectively feeding water into an upper section of said tank, cooling coils acting to chill water in a lower section of said tank, an ultra-violet lamp encapsulated in both the upper and lower sections of the tank for transmitting ultra-violet light rays to water in both upper and lower sections to eliminate bacterial growth in both upper and lower sections, a first faucet communicating with said lower section for dispensing chilled water selectively, a surrounding sleeve spaced from and located about a portion of the ultraviolet lamp, and an outer vessel located below and about a portion of the surrounding sleeve with an opening intermediate the surrounding sleeve and the outer vessel communicating water from the water inlet intermediate the surrounding sleeve and the ultra-violet lamp through the opening and then intermediate the surrounding sleeve and the outer vessel prior to feeding the water into the upper section of said tank in a thin film laminar flow. 13. The water dispenser of claim 12 further comprising a reflective surface in an upper section of the tank. 14. The water dispenser of claim 13 further comprising an encapsulating sleeve about the ultra-violet lamp providing a water free area about the ultra-violet lamp inside the encapsulating sleeve, and water fed from the water inlet passing external to the encapsulating sleeve as it is fed intermediate the surrounding sleeve and the ultra-violet lamp. 15. The water dispenser of claim 14 further comprising a leak detector sensing in the water free area. 16. The water dispenser of claim 15 further comprising a solenoid valve in communication with the water inlet and when the leak detector detects water in the water free area, said solenoid valve is shut. 17. A water dispenser comprising a housing having a water treatment tank, a water inlet selectively feeding water into an upper section of said tank, cooling cold chilled water in the lower section of the tank, and ultra-violet lamp disposed above the upper and lower sections of the tank for transmitting ultra-light rays to water in both upper and lower sections to eliminate bacteria growth in both upper and lower sections, a first faucet communicating with said lower section for dispensing chilled water selectively, and a translucent baffle separating the upper and lower sections of the tank. 18. A water dispenser comprising a housing having a water treatment tank, a water inlet subsequently feeding into an upper section said tank, cooling coils acting to chill water in a lower section of said tank, an ultraviolet lamp disposed in the upper and lower section of the tank for transmitting ultra-violet light rays to water in both upper and lower sections to eliminate bacteria growth in both upper and lower sections, a first faucet communicating with said lower section for dispensing chilled water selectively, a solenoid valve connected to the water inlet; and a controller sensing an open time of the solenoid valve wherein the open time is compared to an expected open time and if the open time exceeds the expected open time, performing one of activating an alarm and closing the solenoid valve. 19. A water dispenser comprising a housing having a water treatment tank, a water inlet selectively feeding water into an upper section of said tank, cooling cold chilled water in the lower section of said tank, an ultra-violet lamp disposed in both the upper and lower sections of the tank for transmitting ultra-light rays to water in both upper and lower sections to eliminate bacteria growth in both upper and lower sections, a first faucet communicating with said lower section for dispensing chilled water selectively, a baffle separating the upper and lower sections of the tank, and an outer vessel located below and about at least a portion of the lamp with said outer vessel connected to the baffle.
