Legionella Treatment for Domestic Water Systems
How can we, at PTS, help with Legionella Treatment for Domestic Water Systems?
Legionella bacteria can proliferate in domestic water systems, posing a significant health risk to homeowners and residents. Effective treatment methods are crucial to prevent the growth and spread of these bacteria, which can cause the potentially fatal Legionnaires’ disease.
In the UK, domestic water systems, including hot and cold water distribution networks, showers, and other water-based appliances, are subject to legionella control regulations and guidelines.
Homeowners and landlords have a legal responsibility to ensure the safety of their water systems and implement appropriate control measures. That why, we at Pipe Testing Services (PTS), are here to help.

Understanding Legionella Treatment for Domestic Water Systems & the Risks
Legionella bacteria thrive in warm, stagnant water conditions commonly found in household water systems. Factors contributing to legionella growth in domestic settings include:
- Water stagnation: Infrequently used taps, TMV’s, showers, and other outlets can lead to water stagnation, providing an ideal environment for legionella growth.
- Low water temperatures: Legionella bacteria can multiply rapidly in water temperatures between 20°C and 45°C.
- Biofilm formation: Biofilms can harbour and protect legionella bacteria, making them resistant to disinfection.
Potential sources of legionella contamination in households include hot water tanks, showerheads, humidifiers, and other water-based appliances. Vulnerable populations, such as the elderly and immunocompromised individuals, are at a higher risk of developing Legionnaires’ disease if exposed to legionella.

Legionella Treatment Methods for Domestic Water Systems
Several legionella water treatment methods can be employed to control and eliminate legionella bacteria in domestic water systems:
Temperature Control
Maintaining appropriate water temperatures is crucial for inhibiting legionella growth. Hot water should be stored and circulated above 60°C (140°F), while cold water temperatures should be kept below 20°C (68°F).
Installing thermostatic mixing valves can help prevent scalding while maintaining high hot water temperatures.

Chemical Disinfection
Chemical disinfection involves using biocides to kill legionella bacteria in water systems. Common disinfectants used in domestic settings include:
- Chlorine: A powerful oxidizing agent that can effectively disinfect water systems.
- Chlorine dioxide: Suitable for treating hot water systems due to its stability at high temperatures.
- Copper-silver ionization: A non-oxidizing biocide that can be effective in controlling legionella growth.

Physical Treatment Methods
Physical treatment methods, such as ultraviolet (UV) light and filtration, can also be employed to eliminate legionella bacteria from domestic water systems. UV disinfection uses high-intensity UV light to inactivate and kill microorganisms, while filtration removes legionella bacteria and other contaminants from water.
Regular Flushing and Cleaning
Regular flushing and cleaning of water systems are essential to remove stagnant water and biofilms that can harbour legionella bacteria. Showerheads, taps, and other outlets should be regularly cleaned and descaled to prevent the accumulation of legionella-friendly environments.
Implementing a Legionella Control Plan
To effectively manage legionella risks in domestic water systems, homeowners and landlords should implement a comprehensive legionella control plan. This plan should include:
Conducting a Legionella Risk Assessment
A legionella risk assessment should be conducted to identify potential sources of contamination and areas of risk within the domestic water system. At PTS, we carry out these types of assessments for any business, facility, residential or commercial property. You can learn more about our services as Legionella Contractors here – on our main page: Legionella Contractors | Pipe Testing Services
Developing a Legionella Management Plan
Based on the risk assessment findings, a legionella management plan should be developed. This plan should outline the control measures to be implemented, such as temperature control, disinfection methods, and flushing schedules. It should also include legionella monitoring procedures and response protocols in case of legionella detection
Maintaining Records and Monitoring
Regular monitoring and record-keeping are essential components of a legionella control plan. Water temperatures, disinfectant levels, and other water quality parameters should be routinely monitored and recorded. Additionally, periodic legionella testing through water sampling and analysis should be conducted to verify the effectiveness of the control measures.
