    What Does Legionella Water Testing Involve?

    Legionella water testing is the process of taking water samples, in sterilised containers, for a reading. These samples are then sent for analysis in a laboratory. The analysis will confirm the absence or presence of Legionella in the water samples, as well as the bacterial count and Legionella species present.

    For accurate results, the water samples must be taken at the right points in the water system. If you are intending to complete testing for Legionella yourself, you will need to know where these points are so you know where you should be taking the samples from. This means you must understand your water system’s design and any areas of risk.

    It is also important you only ever use one sterilised bottle container per outlet to avoid mixing samples from two different points.

    Why is Legionella Water Testing Done?

    The purpose of Legionella sampling and testing is to look for the presence of Legionella bacteria. This bacteria is capable of growing in any purpose-built water system, and when it is breathed in via small water droplets it has the potential to develop into several serious diseases. This includes Legionnaires’ disease – a potentially fatal form of pneumonia.

    All hot and cold water systems that grow sediment, scale, or other forms of bacteria can also provide a feeding ground for Legionella bacteria. If the water temperature is consistently between 20°C and 45°C, there is potential for it to thrive and spread. Combining this with an aerosol release such as the spray from a showerhead) heightens the risk of exposure to the bacteria. In turn, this heightens the risk of contracting diseases.

    Legionella Risk Assessments

    Our Legionella risk assessment service consists of a series of thorough checks of current and previous records with an expert assessment of a site’s hot and cold water systems by skilled technicians.

All instances of non-conformance or compliance are recorded on our online system. This can then send the property owner or manager monthly reports with test results and actions required.

    How Often Should Legionella Water Testing Be Done?

    According to the HSE, the frequency of Legionella water testing will depend on the water system you have and the outcome of a Legionella risk assessment. Open systems such as cooling towers, evaporative condensers, or spa pools need routine testing at least quarterly. However, there are many circumstances where this frequency should be higher.

    When you decide to have Legionella water testing through our service, depending on the unique needs of your site, we may complete onsite Legionella water testing on a monthly, quarterly, or 6-monthly basis.
