It is particularly important to check drinking water dispensers regularly if they are used to supply staff or people in public areas with drinking water.

Risks arise from stagnation, excessively high operating temperatures, filter maintenance backlogs or possible recontamination from contaminated glasses and bottles.

The assessment principles for drinking water dispensers are currently not defined. Many manufacturers of these systems refer to the Min/TafelWV – Mineral and Table Water Ordinance. These classify water from tap water dispensers as table water, resulting in the following microbiological requirements: “Min/TafelWV” §4 paragraph 1 sentences 1 and 2: “Natural mineral water must be free from pathogens.
