How healthy water dispensers are depends on a few factors. On the one hand, it depends on whether it is a fixed water dispenser with a connection to the water pipe or a gallon water dispenser. With fixed water dispensers, tap water is directed directly from the water pipe through hoses into a container. So you tap fresh water, which is one of the most heavily controlled foods in Germany. With gallon water dispensers, water can be drawn from a gallon bottle. If this gallon bottle has been properly filled, transported and stored, you should also not be able to become ill as a result of its consumption.
