Legionella Risk Management During School Holidays

Educational settings, from schools to universities, are tasked with ensuring the safety and well-being of their students and staff year-round. One aspect of safety is Legionella risk management. The threat of Legionella bacteria proliferating in water systems during periods of reduced activity, such as end-of-term holidays, is a matter of concern. In this blog, we will explore Legionella risk management in educational settings, considering both inherent and operational factors, as well as preventive strategies during periods of low usage.

Understanding Legionella Risk

Legionella is a bacterium that thrives in warm, stagnant water. While the original design and setup of water systems in educational settings may incorporate industry best practices, during holiday breaks, many parts of the school, college or university may remain inactive, elevating the operational risk of Legionella contamination.

Effective Legionella Risk Management

Prevent Stagnation: To prevent stagnation, water systems must ensure sufficient water turnover, particularly in areas with low usage. Stagnant water between 20-45°C creates ideal conditions for Legionella growth. Therefore, maintaining adequate temperature differentials is crucial.

Temperature Control: Cold water outlets should consistently be below 20°C, while hot water should be stored above 60°C or no less than 50°C at the outlet. This range helps inhibit bacterial growth.

HSG274 Guidelines: Educational institutions should refer to HSG274 Part 2, Paragraph 2.50 when creating risk mitigation strategies. This guidance is particularly relevant for buildings with intermittent or low usage, offering practical advice on managing them effectively. For detailed information, you can access the document via the following link:

Flushing Protocol: Throughout school holidays, when students and staff are away, and natural water circulation isn’t maintained within educational facilities, it is crucial to implement a flushing protocol during periods of reduced usage. This practice is essential for safe water management and to prevent stagnation. Outlets are now considered infrequently used and should be flushed at a minimum of once a week. However, the optimal flushing frequency may vary depending on the risk assessment for your specific school. Your flushing schedule might need to be as frequent as daily, especially if you have encountered Legionella issues in your school, college, or university. In such cases, we recommend consulting your contractor or contacting us at Dantek, where we can provide expert guidance and assistance.

Legionella Risk Assessment: Carrying out a thorough Legionella risk assessment is a crucial step in proactive Legionella management for educational settings. This assessment acts as a practical tool to pinpoint potential risks and assess how well the current control measures are working. It’s like a roadmap that helps schools, colleges, and universities customize their Legionella prevention strategies to fit their specific situation.

System Maintenance: Systems left unused for extended periods should undergo thorough flushing, cleaning, and disinfection according to British Standards before being recommissioned. This maintenance is essential to prevent potential issues associated with long periods of disuse.

Legionella risk management is a critical aspect of ensuring the safety and well-being of students and staff in educational settings. Proper water system management, temperature control, and adherence to industry guidelines are essential components of a comprehensive Legionella risk management plan. By implementing these strategies, educational settings can reduce the risk of Legionella contamination and create a safe learning and working environments for all, especially during extended breaks when water systems are at their most vulnerable.

Chlorine Dioxide Unit Rental and Flexible Agreements for Effective Water Treatment

Here at Dantek, we manage a collection of Chlorine Dioxide Rental units, which include both Tristel TTec2000 and Grundfos Oxiperm Pro Units. These units are adaptable, with the option for wall or floor mounting, and they can be customized to either dose directly into flowing pipework (whether mains or other) or into a water storage vessel. Additionally, these units possess the capability to dose proportionally based on a pulse-sending water meter or under the control of a Chlorine Dioxide measuring cell.

The limitation of Chlorine Dioxide dosing shares a similarity with temperature in that it relies on water turnover for effectiveness—it can only eliminate the contaminants it meets. Consequently, a Chlorine Dioxide unit cannot directly replace flushing in unoccupied or partially occupied buildings. However, Chlorine Dioxide proves to be a more potent control method compared to temperature alone, especially in addressing biofilm and tackling fouled systems.

Opting for a Chlorine Dioxide unit rental is not cost-effective when the need extends beyond a year; in such cases, purchasing a unit is a more economical choice. The installation costs for rented units can vary and, in certain situations, match those of a permanent installation. This is due to potential expenses related to pipework modifications, the installation of water meters, and the provision of electrical supplies.

Our rental agreements are adaptable in terms of both duration and coverage. Typically, the minimum hire period is one month. We provide a comprehensive service that encompasses installation, commissioning, supply of chemicals, continuous maintenance, de-commissioning, and removal. On the flip side, we also offer ‘dry hire’ options for proficient operators of water treatment equipment.

Our rental units have demonstrated success in various scenarios, including:

  • Before occupation in new buildings, especially in partially occupied ones.
  • Prior to demolition or extensive remodeling in older properties.
  • As a temporary control measure while awaiting other works, such as the installation of new calorifiers or boilers.
  • In situations where speed is crucial, and/or the delivery times for purchased units are extended.
  • As a proof of concept before committing to capital expenditures.

In the world of sports, maintaining pristine playing conditions is of utmost importance. From football and cricket to golf and tennis, the quality of the pitch can greatly impact the performance and safety of athletes. One essential component in maintaining these optimal conditions is the irrigation systems. However, it is crucial to recognize that irrigation systems can also pose potential health risks if not properly managed, specifically when it comes to Legionella contamination.

Legionella bacteria, responsible for causing Legionnaires’ disease, can find a conducive environment within irrigation systems, especially during the summer months when temperatures are high. The presence of warm water coupled with the potential for stagnant water makes these systems an ideal breeding ground for Legionella bacteria. This becomes particularly concerning due to the nature of irrigation systems, which create a large breathable aerosol that can carry across the pitch throughout sports stadiums.

It is vital to highlight the potential risks associated with Legionella contamination in irrigation systems and implement preventive measures to safeguard the health and well-being of athletes, staff, and spectators. While chemical control of the irrigation tank may not be feasible as it can cause damage to the pitch’s structure, regular monitoring and sampling should be conducted to ensure early detection of any Legionella presence.

One of the key aspects to understand is how Legionella bacteria can be inhaled into the lungs. When water droplets are dispersed into the air, such as during the operation of irrigation systems, these droplets can be inadvertently inhaled by individuals nearby. This puts susceptible individuals, particularly those with weakened immune systems or underlying health conditions, at an increased risk of developing Legionnaires’ disease.

To effectively mitigate the risks associated with Legionella contamination in irrigation systems within the sports industry, here are some essential preventive measures that should be implemented:

Regular Maintenance and Cleaning:

Implement a routine maintenance schedule for irrigation systems, ensuring that any potential sources of stagnant water are identified and addressed promptly. Regular cleaning and disinfection of the system will help prevent the growth and spread of Legionella bacteria.

Water Temperature Control:

To minimize the potential accumulation of warm water within the irrigation system, it is essential to install temperature control measures. This can be achieved using temperature sensors and automated controls, ensuring that water temperatures remain outside the optimal range for Legionella growth. Another effective approach is to include your irrigation system in your planned monthly temperature checks, ensuring that any deviations from the desired temperature range are promptly identified and addressed. By actively monitoring and controlling the water temperature, the risk of Legionella proliferation can be significantly reduced.

Adequate Flushing:

To prevent the accumulation of stagnant water, it is crucial to establish a regular flushing regime for the irrigation system. In instances where the system is not fully utilized, thorough flushing before and after each use is recommended. This practice effectively removes any potential contaminants and minimizes the risk of Legionella proliferation. By implementing a proactive flushing routine, the irrigation system remains free from stagnant water, ensuring a safer environment with reduced chances of Legionella contamination.

Water Treatment

Consider incorporating appropriate water treatment methods, such as ultraviolet (UV) disinfection to further reduce the risk of Legionella contamination. However, it is important to ensure that any treatment methods used are suitable for the irrigation system and do not compromise the integrity of the pitch.

Staff Training and Awareness

Educate staff members responsible for operating and maintaining the irrigation system about the risks associated with Legionella bacteria and the importance of implementing preventive measures. Promote a culture of awareness and encourage reporting of any concerns or observations related to the system’s functionality.
