You are active in the housing management and real estate industry or as a private landlord and have to check the drinking water for legionella? Also as an operator of whirlpools, cooling towers and humidifiers you have to subject the water to a legionella examination. Also public institutions, such as kindergartens, schools, hospitals and care facilities are obliged to perform the examination according to the amendment of the German TrinkwV.

Legionella are bacteria that occur in drinking water and can cause diseases. They can enter the human body and thus the lungs via aerosols (e.g. when showering). The result can be severe pneumonia. In hot water pipes in buildings, Legionella bacteria find their preferred growth conditions between 25 °C and 45 °C and can multiply on deposits in the pipe system.

In the field of sampling we are regionally active and work for customers in the area of Saxony as well as southern Brandenburg and Saxony-Anhalt. We carry out legionella tests according to the German Drinking Water Ordinance (TrinkwV), as well as legionella and sediment tests in air conditioning and ventilation systems.
