What is Legionella?

Legionella is a type of bacteria that is found in natural water sources (e.g. ponds, lakes and rivers), as well as purpose-built hot and cold water systems (e.g. spa pools, fountains and waterparks). Legionella can cause Legionnaires Disease when people breathe in tiny droplets of water that contain the bacteria.

The World Health Organization recommends that the concentration of Legionella in water be kept below 100 colony-forming units (CFUs) per millilitre (mL). However, even this level may be too high for some people, such as those who are immunocompromised. Carrying out water testing for Legionella can help you keep your water safe.

Legionnaires Disease: What you need to know

Legionnaires Disease is a severe form of pneumonia that can cause potentially fatal complications in your lungs. This disease is not contagious – it can only be contracted through inhaling water that is contaminated with Legionella bacteria.

Worried about Legionnaires Disease? The symptoms of Legionnaires’ disease are similar to those of other types of pneumonia, and can include:

  • Fever
  • Cough
  • Shortness of breath
  • Chest pain
  • Muscle aches
  • Headache
  • Chills
  • Nausea
  • Diarrhoea

  • Flush hot water taps for at least 30 seconds before using them.
  • Clean and sanitise water systems regularly.
  • Ventilate areas where water is used, such as showers and bathtubs.
  • Keep water moving in pipes and systems to prevent stagnation.
  • Remove any sediment or debris from water systems.

How can a person contract Legionella's Disease?

Legionnaires’ disease can be contracted when water droplets containing Legionella bacteria enter a person’s lungs.

How much could you be fined for Legionella?

The amount you could be fined for Legionella depends on the specifics of each case. In the UK, fines for Legionella can range from £2,500 to £20,000 and you could serve up to 2 years in prison.

  • Public health laboratories

Get in touch with our experts today to get started.

Can you test for Legionella yourself?

Yes, you can test for Legionella yourself. However, it is important to note that home testing kits are not always accurate. If you are concerned about Legionella in your water, it is best to have the water tested by a professional. Speak to one of our experts and we can book you in for Legionella testing.

How often should a landlord do a Legionella test?

The frequency of Legionella testing for landlords will depend on the size and type of building. However, in general, landlords should have their water tested for Legionella at least once a year.

How can I arrange Legionella sampling?

You can arrange Legionella sampling by contacting a water treatment specialist or environmental health officer - like us at Acorn. Get in touch and we can collect a water sample from your home or building and test it for Legionella.

Do I really need to test for Legionella in my domestic water system?

Whether or not you need to carry out Legionella water testing in your domestic water system will depend on a number of factors, including the size and type of building, the location, and the number of people who live there. However, if you are concerned about Legionella, it is always best to have your water tested.

Do I need Legionella testing or a Legionella Risk Assessment?

Legionella testing and legionella risk assessment are two different things. Legionella testing is used to determine whether or not there is Legionella present in your water system. A legionella risk assessment is used to identify the potential risks for Legionella growth in your water system. Not sure which one you need? Our friendly experts are on hand to help - get in touch today.

What are the first steps in preventing Legionella bacteria?

If you want to keep your water systems safe, the best starting point is making sure you have the right people in place. They will need to have completed their Legionella training and must carry out a Legionella Risk Assessment to prevent the risk of Legionnaires' disease on your site. We understand that each business and building is different. That’s why it’s a great idea to have your own person that fully understands how your unique system works. But don’t worry if this isn’t an option - our experts are here to take the weight off your shoulders. We have years of experience in carrying out Legionella testing on all types of water systems. Trust us to complete your Legionella testing efficiently, thoroughly and in line with strict industry standards.

Where and when you find Legionella

Legionella bacteria can be found in a wide range of different water systems. That being said, it is most likely to be present if the water meets one or all of the following:

  • The water temperature is maintained between 20°C and 45°C
  • Has nutrients
  • Is stagnant (i.e. not moving)

Some of the most common water systems that can be homes for Legionella bacteria include:

  • Hot water tanks
  • Cooling towers
  • Domestic hot and cold water systems
  • Hot tubs
  • Showers

What’s the difference between Legionella testing and sampling?

In short, there is no difference! Sampling just refers to the process of collecting the water sample, before it is sent off for testing. At Acorn, you can always expect professional and efficient legionella sampling services, done in line with recognised British standards. Ready to take control of your water hygiene process? Give our team of experts a call today - we are on hand to answer any questions you may have.

How often should you carry out Legionella testing?

How often you carry out Legionella testing depends on the type of water system you have and the outcome of your Legionella Risk Assessment. Generally, though, you can follow these guidelines:

  • Open systems (such as cooling towers or spa pools) should be tested at least quarterly, unless circumstances require more frequent sampling.
  • Hot and cold water systems are not open to the elements and so have a lower risk of contamination. Because of this, monitoring the system isn’t always necessary, unless a risk assessment pulls up a concern.

What factors influence Legionella testing in Manchester?

Every building has its own unique water system and so, in certain environments, the risk for Legionella contamination is higher. In fact, different sectors and industries have their own factors to consider:

  • Healthcare - Because places such as hospitals and care homes have complex water systems that serve vulnerable people, the risk for contamination and transmission is much higher.
  • Hospitality - Large resorts or hotels often have hot tubs or even decorative fountains. Since these water systems are often stagnant and maintained at level temperatures, they are the perfect breeding ground for Legionella bacteria.
  • Public facilities - Leisure centres or public swimming pools with warm water systems also provide ideal conditions for Legionella growth and so have a high risk for contamination.

No one wants to endanger public health, which is why it’s so important to keep on top of your Legionella water testing. Get in touch with our experts today for professional services and complete peace of mind.

Why should you test for Legionella?

You should regularly test for Legionella bacteria to protect public health and make sure your water systems are safe. Legionella is a type of bacteria that can cause Legionnaires' disease, a serious and potentially fatal lung infection. Legionella bacteria can grow in warm water systems, such as cooling towers, evaporative condensers, spa pools, and hot water tanks.

How long does a Legionella test take to complete?

A Legionella test typically takes 10-14 days to complete. This includes the time it takes to collect the water sample, transport it to the laboratory, and culture the bacteria.

How long does it take to receive the results from a Legionella test?

The results of a Legionella test are typically available within 10-14 days after the water sample is collected.
