A supply system and method for providing water from a bottled water cooler includes a pump which pumps water from an upright bottle of water into a water reservoir in the bottled water cooler. A control device using a microcontroller monitors upper and lower sensors which are disposed in the water reservoir, and controls the operation of the pump so that the water level in the reservoir goes no lower than the lower sensor, and goes no higher than the upper sensor. The control device also monitors a sensor disposed at the bottom of the bottle of water, and de-energizes the pump if the bottle of water is empty.
