What is Legionella and Why is Water Treatment Necessary?
Legionella is a type of bacteria that can cause Legionnaires’ disease, a severe form of pneumonia, when inhaled through contaminated water droplets. These bacteria thrive in warm, stagnant water conditions commonly found in building water systems, such as hot and cold water distribution networks, cooling towers, storage tanks and other water-based equipment.
Legionella water treatment is crucial to prevent the growth and spread of these harmful bacteria, ensuring a safe environment for employees, tenants, and visitors.
Comprehensive Legionella Water Treatment Strategies
We implement comprehensive legionella water treatment strategies tailored to your specific needs. Our approach encompasses the following key elements:
Risk Assessment and Management Plan
Our process begins with a thorough legionella risk assessment to identify potential sources of contamination and areas of risk within your water systems. Based on the findings, we develop and implement a robust legionella management plan outlining control measures, legionella monitoring procedures, and response protocols.
Temperature Control
Maintaining appropriate water temperatures is crucial for inhibiting legionella growth. We ensure that hot water temperatures are kept above 60°C (140°F) and cold water temperatures below 20°C (68°F). Additionally, we install thermostatic mixing valves to prevent scalding while maintaining high hot water temperatures.
Water Treatment Methods for Legionella
We employ various proven water treatment methods to effectively eliminate legionella bacteria. These include:
- Chemical disinfection using oxidizing biocides such as chlorine and chlorine dioxide, as well as non-oxidizing biocides like copper-silver ionization.
- Chlorination is a highly effective method for legionella control in water systems. Chlorine is a powerful oxidizing agent that can kill legionella and other harmful bacteria by disrupting their cell structures. We use controlled chlorine dosing to maintain appropriate residual chlorine levels throughout the water system, ensuring continuous disinfection.
- For hot water systems, we may recommend chlorine dioxide treatment. Chlorine dioxide is a highly reactive biocide that remains stable at higher temperatures, making it ideal for treating hot water circuits prone to legionella growth.
- In addition to chemical disinfection, we also employ physical treatment methods like filtration to remove legionella bacteria and other contaminants from water systems.
- Regular flushing and cleaning of water systems are crucial to remove stagnant water and biofilms, which can harbour legionella bacteria and reduce the effectiveness of disinfection treatments.
Our experienced legionella contractors carefully assess your specific water system and conditions to determine the most appropriate and efficient combination of water treatment methods. We follow industry best practices and guidelines to ensure comprehensive legionella control and compliance with relevant regulations.

Monitoring and Testing – Legionella Water Treatment
Regular monitoring and testing are essential to verify the effectiveness of our legionella water treatment strategies.
We routinely monitor water temperatures, biocide levels, and other water quality parameters. Additionally, we conduct periodic legionella testing through water sampling and analysis to ensure your water systems remain safe.
Maintenance and Record-Keeping
Proper maintenance and record-keeping are vital components of our legionella water treatment services. We implement a regular maintenance program for water systems, including legionella inspections, cleaning, and repairs.
Moreover, we keep detailed records of all legionella control measures, monitoring results, and maintenance activities for compliance purposes.
