    Why Do Hot and Cold Water Systems Need to Be Disinfected?

    Any hot and cold water system and any recirculated system are both at risk of Legionella bacteria multiplying. Legionella bacteria occur in natural water sources but typically only multiply into dangerous colonies in artificial water sources.

    Exposure to this growth of Legionella happens when breathable water droplets are spread. This is dangerous because it can lead to the development of Legionnaires’ disease, a severe form of pneumonia that is sometimes fatal. 

    People at significantly higher risk include:

    • Smokers and people with respiratory diseases
    • Heavy drinkers
    • People with diabetes, heart disease or lung conditions
    • The over-45s
    • People with kidney disease.
    • Those with impaired immune systems

    High-Risk Water Systems that Support Legionella Growth

    The most common systems which support the dangerous growth of Legionella include:

    • Spa pools
    • Hot tubs
    • Swimming pools
    • Dental apparatus
    • Showers
    • Healthcare Properties
    • Vehicle cleaning machines
    • Food manufacturing sites
    • Washing facilities
    • Water jets
    • Sprinklers
    • Industrial facilities like manufacturing sites

    What Conditions Cause Legionella Growth?

    Legionella bacteria will grow and thrive when 4 key elements combine:

    1. Habitat
    2. Food source
    3. Warm temperatures
    4. Aerosol release

    When a water system has sediment and limescale, is frequently between 20-45 degrees celsius, and water droplets are at risk of aerosol release, Legionella bacteria can thrive and spread.

    This is why comprehensive Legionella Risk Assessments are a legal requirement. Once your assessment has been completed, any high-risk areas will be identified. You can then work on monitoring and controlling Legionella bacteria in water systems to prevent its spread and reduce the risks associated.

    Preventative Measures: Legionella Temperature Monitoring

    One of the most important preventative measures against the spread of Legionella bacteria is temperature monitoring. Our technicians are fully accredited in monitoring the temperature of water systems in line with current legislation surrounding Legionella compliance. 

    We can provide monthly checks of hot and cold water temperatures, recording each temperature measurement and monitoring them over time to improve the management of Legionella risks and assess the control measures in place.

    As part of our comprehensive range of Legionella services, we provide various disinfection treatments for a wide variety of clients. We use stabilised silver hydrogen peroxide to ensure the system is disinfected. This powerful chemical can penetrate biofilm and provides the optimum solution for minimal disruption on site.

    Our services include:

    • Mains injection system disinfection
    • Cleaning and disinfection of cold water storage tanks
    • Hot water system disinfections
