Necessity of legionella testing

There is an obligation to test for legionella for operators of "large-scale systems" for water heating from which drinking water is supplied as part of a commercial or public activity. "Large systems" are drinking water heaters with a capacity of more than 400 liters or pipelines with a capacity of more than 3 liters leading to the tapping point.

Commercially used properties such as apartment buildings are subject to an inspection obligation at intervals of 3 years if the water is heated centrally.

Facilities that offer services to the general public and that are used by a changing group of people have a public character. These include hotels, retirement homes and nursing homes, day care centers and schools, hospitals, swimming pools and saunas, sports facilities and campsites. Here, there is an annual obligation for legionella testing.

Newly commissioned drinking water systems must be tested for legionella for the first time within three to twelve months at the latest, according to § 14b para. 6 TrinkwV.

For other areas and stationary systems with nebulization of water in any form, a corresponding examination is also urgently recommended as part of the duty of care. Examples are dentist and ENT practices, social areas of companies, air conditioning systems and humidifiers.

Things to know about legionella

Legionella are bacteria that multiply in hot water and can cause severe respiratory diseases. Their temperature optimum is between 30 °C and 45 °C. However, they are viable in a temperature range of 5 °C - approx. 60 °C.

Particularly strong growth can be observed in dead pipes, water pipes with irregular use and insufficiently high water temperature or during stagnation. Sensorically, infested drinking water is inconspicuous.

By inhaling aerosols - finely atomized water droplets - Legionella can reach the deeper parts of the lungs and cause flu-like illnesses (Pontiac fever) but also severe pneumonia, the so-called Legionnaires' disease. Aerosols are produced, for example, during showers, in whirlpools, by humidifier systems or the output of cooling towers, evaporative cooling systems or wet separators.
