Infestation with legionella - not only drinking water is affected

Legionella in waterworks can be hazardous to human health

The Drinking Water Ordinance and the EU Drinking Water Directive define that water must be easily digestible and available to humans at all times. To achieve this, operators of systems for continuous water distribution with a large system for DHW heating are obliged to carry out a Legionella test at least every three years.

Legionella pose the greatest health hazard to humans in drinking water. Therefore, large plants are subject to a duty of disclosure. However, care must also be taken in relation to other types of water. Several cases in recent years have shown that circulation water contaminated by Legionella in cooling towers and evaporative cooling systems can be the cause of infections. Some of the diseases can be fatal.
