Our wastewater treatment services help reduce your costs and environmental impact.
Having clean and safe water is essential for our health and well-being. But if the water is not properly maintained, it can lead to dangerous levels of Legionella bacteria. Legionella is a type of bacteria found naturally in water, but if it is not controlled, it can lead to serious illnesses like Legionnaires’ Disease. In this article, we’ll explore how to prevent Legionella in water and keep you and your family safe from potential harm.
How to Prevent Legionella in Water?
- Install and maintain the right temperature for the hot water system.
- Regularly test the water for Legionella bacteria.
- Install a device that filters out Legionella bacteria from water.
- Regularly clean and disinfect the plumbing system.
- Ensure that water tanks and pipes are insulated.
- Make sure that cooling towers are regularly maintained and cleaned.
- Ensure that all shower heads and taps are regularly cleaned and disinfected.

What is Legionella in Water?
Legionella is a type of bacteria that can be found in natural water sources and in human-made water systems. It is most commonly found in warm environments, such as hot tubs and cooling towers. It is the cause of Legionnaires’ disease, a type of pneumonia that can be fatal. In order to prevent the spread of Legionella and protect the health of those who come in contact with water sources that are contaminated, there are a few steps that can be taken.
What Are the Risks of Legionella?
The risks of Legionella in water sources can be serious and include the spread of Legionnaires’ disease. When Legionella is present in a water source, it can be spread through the aerosolization of the bacteria, which is when tiny droplets of water containing the bacteria are released into the air. This can happen when contaminated water is used in showers, hot tubs, and cooling towers. Those who inhale the contaminated aerosolized water droplets are at risk of developing Legionnaires’ disease, which can be fatal in some cases.
What Steps Can Be Taken to Prevent Legionella?
In order to prevent the spread of Legionella, a few steps can be taken. Firstly, water sources that are susceptible to contamination should be regularly checked and tested to ensure they are free from Legionella. Testing kits can be purchased from many health and safety suppliers and should be used regularly on all water sources. This will help to identify any potential sources of contamination and allow for the necessary preventative measures to be taken.

Additionally, water sources should be regularly flushed with fresh water to ensure that any bacteria that may be present is removed from the water source. This should be done on a regular basis, as stagnant water can become a breeding ground for bacteria.
Finally, any equipment that is used to treat the water should be regularly checked and maintained in order to ensure that it is functioning correctly. This includes filters and UV lights, which should be checked and replaced regularly in order to ensure that they are working properly.
Cleaning and Disinfecting Water Sources to Prevent Legionella
In order to prevent the spread of Legionella, it is important to regularly clean and disinfect water sources. This should be done on a regular basis and should include deep cleaning and sanitizing of all surfaces and equipment that comes in contact with the water. This will help to remove any bacterial colonies that may be present in the water and prevent them from spreading.
Cleaning and Sanitizing Surfaces and Equipment
When cleaning and sanitizing surfaces and equipment that come in contact with the water, it is important to use detergents and disinfectants that are specifically designed to kill Legionella. These products should be used according to the manufacturer’s instructions, as different products may require different dilution rates and contact times in order to be effective.
Maintaining Good Hygiene Practices
In addition to cleaning and sanitizing surfaces and equipment, it is also important to maintain good hygiene practices. This includes washing hands after coming into contact with contaminated water, as well as ensuring that any equipment that comes into contact with the water is regularly disinfected. This will help to reduce the risk of Legionella spreading and prevent potential illness.
Using Water Temperature to Control Legionella
One of the most effective methods of controlling Legionella is to control the temperature of the water sources. This is because the bacteria thrive in warm water, so keeping the water at a temperature below 55 degrees Celsius can help to prevent Legionella from spreading.
Controlling Hot Water Temperatures
In order to control the temperature of hot water sources, such as hot tubs and showers, it is important to install thermostatic mixing valves. These valves will ensure that the water is kept at a safe temperature, and can be adjusted as needed.
Controlling Cooling Tower Temperatures
For cooling towers, it is important to install temperature control systems that can be used to adjust the temperature of the water as needed. This will help to ensure that the water is kept at a safe temperature and help to prevent Legionella from spreading.
Using Water Treatment to Prevent Legionella
In addition to controlling water temperatures, water can also be treated in order to prevent the spread of Legionella. This can be done using filtration systems, ultraviolet light, or chemical treatments.
Using Filtration Systems to Remove Legionella
Filtration systems can be used to filter out bacteria, including Legionella, from water sources. This can be done using a variety of different filtration systems, including sand filters, cartridge filters, and ultraviolet filters.
Using Ultraviolet Light to Kill Legionella
Ultraviolet light can also be used to kill Legionella in water sources. This is done by exposing the water to ultraviolet light, which will kill any bacteria that is present in the water.
Conclusion
Preventing the spread of Legionella in water sources is important in order to protect the health of those who come in contact with the water. By regularly testing and cleaning water sources, controlling water temperatures, and using water treatments, it is possible to reduce the risk of Legionella spreading and protect those who come in contact with it.
