Plumbing Best Practices for Preventing Legionella

Legionella bacteria, the cause of Legionnaires’ disease, pose a significant health risk in commercial buildings if not properly managed. Ensuring water systems are free from this bacterium is crucial for the safety and well-being of all occupants. This blog delves into the best practices for preventing Legionella, the importance of regular maintenance, and how Brooktech can assist in safeguarding your commercial property.

Understanding Legionella and Its Risks

Legionella bacteria thrive in water systems, particularly in warm, stagnant water. They can cause Legionnaires’ disease, a severe form of pneumonia, and Pontiac fever, a milder illness. The bacteria spread through inhalation of contaminated water droplets from sources like cooling towers, showers, and hot tubs. According to the Health and Safety Executive (HSE), Legionella bacteria can multiply rapidly between 20-45°C, making regular monitoring and maintenance essential.

Best Practices for Preventing Legionella

1. Conduct Regular Risk Assessments

Conducting thorough risk assessments is the first step in preventing Legionella. These assessments identify potential hazards within your water systems and help develop a management plan. According to the HSE, risk assessments should be reviewed regularly, especially after any changes to the water system.

2. Implement Temperature Control

Maintaining water temperatures outside the range that supports Legionella growth is crucial. Hot water should be stored at 60°C and distributed at 50°C or higher, while cold water should be kept below 20°C. This temperature control helps prevent the bacteria from multiplying.

3. Regular Flushing of Water Systems

Stagnant water can become a breeding ground for Legionella. Regularly flushing unused outlets, such as taps and showers, ensures fresh water circulates through the system, reducing the risk of contamination.

4. Clean and Disinfect Water Systems

Regular cleaning and disinfection of water systems, including cooling towers, hot tubs, and storage tanks, are essential. Using appropriate biocides and disinfectants can effectively control bacterial growth.

5. Install and Maintain Water Treatment Systems

Water treatment systems, such as filtration and chlorination, can significantly reduce Legionella risk. These systems need regular maintenance and monitoring to ensure they operate effectively. According to the British Standards Institution (BSI), compliance with standards like BS 8580-1:2019 for water quality risk assessments is vital.

Regular Maintenance and Monitoring

6. Regular Monitoring

Monitoring water systems for temperature, biocide levels, and signs of contamination is crucial. Regular testing for Legionella bacteria helps detect issues early and allows for prompt corrective actions.

7. Record Keeping

Maintaining detailed records of all risk assessments, monitoring results, and maintenance activities is essential for compliance and effective management. These records provide a clear history of water system management and help identify trends or recurring issues.
