What Water Temperature Kills Legionella?

Legionnaires’ disease is a very real risk in water systems for commercial buildings. While tap water is usually safe in the UK, employers and anyone else in charge of a building have a duty to mitigate risks from waterborne pathogens and bacteria in their buildings (Health and Safety Executive).

Billi UK combines innovation, safety, and sustainability to offer water systems that provide instant access to boiling, chilled, sparkling, and still water while safeguarding against Legionella and other nasties.

Does Boiling Water Kill Legionella?

Legionella, the notorious bacteria behind Legionnaires’ and other Legionellosis diseases is found in water temperatures ranging from 20–45 °C. This makes man-made water systems potential breeding grounds if not properly monitored and managed, and with an English business being fined as recently as 2023 for failing to manage the risk of Legionella, it’s clear to see why having a water system that reliably produces clean and safe water is so important.

The key to preventing the growth and spread of Legionella lies in understanding these risks and implementing effective control measures. By ensuring water is either below 20 °C or above 60 °C, the risk of Legionella growth is significantly reduced. Specifically, water temperatures above 60 °C are known to kill Legionella, providing a reliable method to sanitise water systems.

Billi UK takes water hygiene a step further, with our advanced Sub Micron filters effectively removing heavy metals, parasitic cysts like Giardia, and even the bacteria that cause Legionnaires’ disease. Ensuring that even when they aren’t using our units for convenient instant boiling water, no one has to wonder if they can get legionnaires disease from drinking water in your building.
