Best Practices for Legionella Control

Introduction

Effective management of water systems is crucial for controlling Legionella bacteria and preventing associated risks in various environments.

Best Practices for Hot and Cold Water Systems

Risk Assessment

Conduct a risk assessment to identify potential sources of Legionella and evaluate the associated risks.

Temperature Control

Implement appropriate temperature control measures to keep water outside the optimal growth range of 20 to 45 degrees C.

Monitoring and Testing

Regularly monitor and test the water system to ensure effectiveness of control measures in preventing Legionella growth.

Cleaning and Disinfection

Regularly clean and disinfect the water system to remove sediment and biofilm that can harbour Legionella bacteria.

Best Practices for Cooling Towers and Evaporative Condensers

Risk Assessment

Conduct a risk assessment to identify potential sources of Legionella and assess the level of risk associated.

Control Measures

Implement appropriate control measures including regular cleaning, disinfection, and maintaining correct water temperatures.

Monitoring and Testing

Regularly monitor and test the water system to ensure the control measures effectively prevent Legionella growth.

Maintenance

Implement appropriate maintenance measures to ensure the proper operation of cooling towers or evaporative condensers.

Best Practices for Spa Pools and Hot Tubs

Risk Assessment

Conduct a risk assessment to identify potential sources of Legionella and assess the level of risk.

Control Measures

Implement appropriate control measures including regular cleaning, disinfection, and maintaining correct water temperatures.

Monitoring and Testing

Regularly monitor and test the water system to ensure the control measures effectively prevent Legionella growth.

Operation

Ensure correct operation of spa pools or hot tubs with proper water circulation and filtration systems.
