  • Legionella

    Although legionella bacteria are widely distributed in the aquatic environment and can be found in all types of water only certain strains cause legionellosis, a collective term for diseases caused by legionella bacteria including the most serious Legionnaires’ disease, a severe and potentially fatal form of pneumonia.

    In drinking water, legionella bacteria are controlled by disinfection of supplies which is effective at killing them.

    Legionella bacteria only become a risk to health where conditions, particularly warm temperatures, exist that allows them to grow and survive. Legionellae can be inhaled if released in large numbers into the air as a fine mist of water droplets. This can occur in poorly designed, installed or maintained artificial water systems such as cooling towers, hot and cold water systems and spa pool.

    All organisations or self-employed individuals, including those who rent property or rooms in their home are responsible for the water system in their premises. They have a legal duty to ensure that any risk of exposure to Legionellae, for those working and living in their premises, is assessed and controlled properly.

    A competent person must perform a Legionella risk assessment.

    We do not provide advice or or a risk management service for legionellae. For more information, please contact a suitably qualified independent expert.

    Wessex Water Scientific Services does carry out Legionella testing.
