Legionella Control for Water Tanks

    Effective legionella control for water tanks is crucial in preventing the growth and spread of Legionella bacteria.

    This harmful bacteria thrives in warm, stagnant water conditions, making water tanks a potential breeding ground if proper precautions are not taken.

    Water Tank Temperature Control for Legionella

    Maintaining appropriate water temperatures is a key strategy for legionella control in water tanks.

    Hot water tanks should store water at 60°C (140°F) or higher, while cold water tanks should be kept below 20°C (68°F). This temperature range inhibits Legionella growth. Proper insulation and temperature monitoring systems are vital to maintain these conditions.

    Regular Inspections and Water Tank Cleaning for Legionella

    Regular inspections and thorough cleaning are paramount to prevent Legionella bacteria growth within water tanks. Even the slightest traces of sediment, biofilm, or other contaminants can foster these harmful microorganisms.

    Our experienced professionals meticulously adhere to industry best practices, following strict protocols for water tank cleaning. This ensures effective Legionella control. The process typically includes the following steps:


    We completely drain the water tank, removing any stagnant water that may harbour Legionella bacteria.

    Our technicians then perform a comprehensive physical cleaning of the tank’s interior surfaces. This involves removing any accumulated sediment, scale, or biofilm that could potentially harbour Legionella growth.

    After the physical cleaning, we use approved and effective disinfection methods, such as chlorination or other biocidal treatments, to eliminate any remaining Legionella bacteria or other microorganisms present in the water tank.

    Once the disinfection process is complete, we thoroughly rinse and flush the water tank to remove any residual disinfectants or debris.

    Before putting the water tank back into service, we conduct a final inspection and testing to ensure the effectiveness of the cleaning and disinfection processes. This may involve taking water samples for Legionella testing to confirm the absence of the bacteria.

    The frequency of cleaning and disinfection should be determined based on a comprehensive legionella risk assessment, considering factors such as the tank size, water usage patterns, and potential risk to occupants or users.

    Importantly, we follow all relevant regulations and industry guidelines for water tank cleaning and legionella control. Our team uses the latest techniques and equipment to ensure thorough and effective cleaning, disinfection, and testing processes.

    In Need of a Legionella Control for Water Tanks?

    Water Tank Disinfection for Legionella

    Disinfection methods, such as chlorination or other approved biocides, may be employed for legionella control in water tanks. These methods effectively eliminate Legionella bacteria from water tanks and associated pipework. Proper dosing and contact times are essential for successful disinfection.

    Water Tank Design for Legionella Prevention

    To prevent bacterial growth, designers should minimise stagnation and dead legs in water systems, where water can become stagnant. Additionally, they must insulate the systems, use tank covers, and select materials that discourage biofilm formation. These considerations are crucial for effective legionella prevention in water tanks.


    What are Dead Legs?

    Dead legs are stagnant sections of water piping systems where water does not flow or circulate properly. These isolated pipe segments can occur when pipes are installed for future use but left unused, or when fixtures or equipment are removed without adequately disconnecting the pipes. The lack of water flow in dead legs allows bacteria like Legionella to grow and multiply, as disinfectants in the stagnant water become depleted over time. To mitigate the risks of Legionnaires’ disease, dead legs should be identified, removed if possible, or regularly flushed to prevent the build-up of harmful bacteria.

    Legionella Monitoring and Testing for Water Tanks

    Our approach involves a comprehensive monitoring program that includes:

    Regular legionella monitoring and testing are essential components of an effective legionella control program for water tanks. It allows us to:

    • Evaluate the efficacy of implemented control measures, such as temperature management, disinfection, and cleaning protocols.
    • Identify potential sources of Legionella contamination early, before they become a significant health risk.
    • Monitor trends and patterns in Legionella levels over time, enabling proactive adjustments to the control strategies.
    • Demonstrate compliance with relevant regulations and industry standards.

    Regulations for Legionella Control in Domestic Water Tanks (UK)

    In the United Kingdom, there are specific regulations and guidelines set forth by authorities such as the Health and Safety Executive (HSE) and the Approved Code of Practice (ACOP) that outline requirements for legionella control in water systems, including domestic water tanks. Compliance with these regulations is mandatory.
