A water treatment tank for use with water purification apparatus including an ultra-violet lamp (32) within a bulb (30) onto which incoming water is directed to provide a thin laminar flow about the bulb. The tank may have two compartments (58, 60), the ultra-violet lamp and bulb extend through both compartments and a baffle (24) to purify the water. A controller (80) operates a switch (34) to turn the normally off UV lamp on before opening a fill valve (376) to replenish water in the tank. The lamp is turned off after a first run time. The water level is sensed by a low and high level limit which allow for a volume of water in the tank which may be utilized without necessitating operation of the lamp upon each dispensing of water from the tank.
