    Key Components of a Legionella Prevention Plan

    A legionella prevention plan should include the following key elements:

    Risk Assessment

    Thorough evaluation of water systems to identify potential sources of legionella growth and areas of concern. At PTS, we perform legionella risk assessments regularly for our clients.

    Regular legionella monitoring, testing, maintenance, and appropriate control measures like temperature regulation, disinfection, and legionella water treatment.

    Educating staff and occupants on legionella risks and the importance of following proper procedures.

    Maintaining detailed records of all legionella prevention activities, including risk assessments, test results, maintenance logs, and corrective actions.

    Periodic inspections and audits of water systems and prevention measures to ensure compliance and identify areas for improvement.

    Procedures for notification, remediation, and communication with authorities and stakeholders in case of a legionella outbreak.

    Our risk analysis process involves a physical inspection of the hot and cold water distribution networks, storage tanks, and outlets.

    Water sampling and testing for the presence of legionella bacteria is essential. Evaluating water temperatures, flow rates, and identifying potential stagnation points is crucial. Moreover, a thorough review of the system design, operation, and maintenance procedures should be conducted to identify potential vulnerabilities.

    Healthcare Facilities

    Hospitals, nursing homes, and other healthcare facilities are particularly susceptible to legionella outbreaks due to their complex water systems, including cooling towers, hydrotherapy pools, and equipment that can aerosolize water.

    Moreover, patients and residents are often immunocompromised, making them more vulnerable to Legionnaires’ disease. A legionella prevention plan in healthcare settings should include:

    Hotels and Resorts

    Hotels, resorts, and other hospitality establishments have numerous potential sources of legionella growth, such as hot tubs, decorative fountains, and showerheads in guest rooms.

    A legionella outbreak in these facilities can severely damage their reputation and lead to costly lawsuits. A legionella prevention plan for the hospitality industry should focus on:

    Educational Institutions


    Schools, universities, and other educational facilities often have aging water infrastructure, increasing the risk of legionella growth. Additionally, the presence of vulnerable populations, such as young children and immunocompromised individuals, heightens the need for rigorous prevention measures. A legionella prevention plan for educational institutions should include:

    Industrial and Manufacturing Facilities

    Industrial plants, manufacturing facilities, and other commercial buildings with complex water systems are prime environments for legionella growth. Cooling towers, storage tanks, and piping networks can harbour the bacteria, posing risks to employees and visitors. A legionella prevention plan for industrial settings should focus on:

    Legionella Prevention Plan - FAQs

    What are the most common sources of legionella in commercial buildings?

    Common sources include cooling towers, hot tubs, and decorative fountains, large plumbing systems with areas of stagnant water, and equipment that can aerosolize contaminated water droplets, such as showers, faucets, and humidifiers.

    Larger buildings with more complex water systems generally require more extensive prevention measures. This may include more frequent risk assessments, increased water sampling and testing, and additional control methods like secondary disinfection.

    Yes, industries like healthcare, hospitality, and manufacturing may have additional regulatory requirements or guidelines for legionella prevention due to the increased risks associated with their operations and the vulnerability of their occupants or visitors.

    New construction projects should consider legionella prevention from the design stage, incorporating measures like minimising dead legs in plumbing systems, selecting appropriate materials, and providing access for future maintenance and disinfection. Implementing a water management plan during construction is also crucial.

    Water treatment methods like chlorination can be effective in controlling legionella growth in water systems. However, these methods should be part of a comprehensive prevention plan that also includes risk assessments, temperature control, and other maintenance procedures.

    Building managers should establish clear protocols for regular inspections, testing, record-keeping, and auditing of their legionella prevention measures. Partnering with experienced legionella contractors like PTS can help ensure ongoing compliance and provide expert guidance on best practices.

    In the event of an outbreak, immediate remediation measures should be taken to disinfect the water system and eliminate the source of contamination. Notification protocols should also be in place to inform relevant authorities, building occupants, and the public as necessary. A thorough investigation and review of the prevention plan should follow.
