How does Legionella spread?

Legionella is a bacterium that can cause two illnesses: Legionnaires’ disease, a severe pneumonia, and Pontiac fever, a milder flu-like condition. It naturally exists in soil, lakes, and freshwater systems but can proliferate in man-made water networks, such as plumbing systems, showers, cooling towers, and hot tubs.

The bacteria spread through aerosolised water droplets, which form when water flows through fixtures like shower heads, faucet aerators, or spa bubbles. Inhaling these tiny droplets allows Legionella to reach the lungs and cause infection.

Legionella thrives in water temperatures between 20°C and 45°C, especially in systems with stagnant water or biofilm buildup. Even if you carefully control water temperatures, biofilm can harbor and protect bacteria, allowing them to persist in the system. Studies have also shown that Legionella can survive at temperatures as high as 70°C when living inside amoebas, making it even harder to eliminate.

How it works

Common risk areas for Legionella

Legionella can thrive in various water systems where conditions allow for bacterias to grow. Common risk areas include:

  • Cooling towers
  • Hot tubs and spas
  • Decorative fountains
  • Shower heads and faucets
  • Water storage tanks
  • Humidifiers and misting systems

A matter of security

Ensuring bacteria-free water is not just a legal requirement—it is fundamental for the health and safety of anyone using a property or public facility. Whether in residential buildings, hotels, hospitals, or industrial spaces, water quality plays a crucial role in maintaining trust and safeguarding well-being.

Legionella and other harmful bacteria can thrive in poorly maintained water systems, posing serious health risks such as Legionnaires’ disease. For property owners and facility managers, ensuring that water is safe to use and drink is not only a responsibility but also a key component of delivering a safe environment for residents, employees, and visitors.

Being able to guarantee bacteria-free water is a basic requirement in a property or public environment. Visitors and users must feel safe using and drinking the water without the risk of ingesting unhealthy and harmful bacteria.

Frequently Asked Questions

How does Legionella spread in water systems?

Legionella spreads through aerosolized water droplets, often created by fixtures like showerheads, faucets, or cooling towers. These droplets, when inhaled, allow the bacteria to enter the lungs. Legionella can grow in both hot and cold water systems, for example, when heat transfer from hot water pipes warms nearby cold water pipes. Factors like stagnant water, biofilm buildup, and temperatures between 20°C and 45°C further increase the risk of Legionella proliferation in water systems.

How often should I test for Legionella?

The frequency depends on several factors, including the size and use of the property. For larger buildings with complex water systems, testing may be required multiple times a year. However, we recommend conducting tests at least once annually to ensure safety.

What should I do if the test shows the presence of Legionella bacteria?

Step 1: Limit the Risk The first step after detecting Legionella is to immediately take action to minimize exposure risk. This might involve temporarily shutting down parts of the water system or implementing strict usage restrictions until further measures can be taken.

 

Step 2: Take Immediate Action If Legionella levels are very high and need to be reduced quickly, immediate measures such as hot water flushing or shock chlorination may be necessary. These point interventions can help reduce Legionella levels quickly. However, if you don’t change the conditions in your water system - the bacteria will return over time. With Anolytech’s method, you get a permanent solution that guarantees bacteria-free water 24/7 by addressing the root causes of Legionella growth.

 

Step 3: Implement Preventive Measures After sanitation, it is essential to implement preventive measures to avoid future outbreaks. Anolytech provides a water disinfection solution to ensure your water system remains bacteria-free. Our method not only eliminates existing bacteria but also prevents future growth, offering long-term safety and peace of mind.

How can I prevent Legionella in my water system?

Maintaining water temperatures outside Legionella’s growth range (below 20°C or above 50°C) is a common approach but has shown limited effectiveness as a standalone solution. Preventing water stagnation through proper system design and regular use is also critical. For more reliable prevention, Anolytech’s continuous disinfection system uses AnoDes to eliminate bacteria without harmful chemicals, ensuring long-term safety and compliance for your water system.
