Legionella Cleaning FAQs

 

 

Legionella cleaning involves removing legionella bacteria and biofilm from water systems to prevent the growth and spread of this harmful bacteria. It is essential to protect public health and comply with legal duties.

The frequency depends on your risk assessment and water system usage, but regular cleaning and disinfection are recommended, especially for high-risk systems such as cooling towers, hot water cylinders, and cold water storage tanks.

Common methods include thermal disinfection (high-temperature flushing), chemical treatment with biocides like chlorine dioxide, copper and silver ionisation, and system flushing and cleaning.

The legal responsibility lies with employers, landlords, and building managers to carry out legionella risk assessments and implement control measures to prevent legionella growth.

While complete eradication is challenging, effective legionella cleaning and control measures significantly reduce bacteria counts and prevent legionella growth to safe levels.

Legionella bacteria multiply between 20°C and 45°C. Keeping hot water above 60°C and cold water below 20°C inhibits bacterial growth and is a key control measure.

Dead legs are sections of pipe work where water stagnates, promoting legionella growth. Removing or flushing these regularly helps minimise legionella risks.

Yes, routine water sampling, temperature checks, and system inspections by a competent person are vital to ensure control measures remain effective and compliant.
