What is Legionella?

Legionnaire’s disease also known as Legionellosis is an infectious disease caused by any type of Legionella bacteria but main contributor is Legionella pneumophila SG1. Typical symptoms can include shortness of breath, headaches and vomiting, similar to the symptoms of pneumonia.

Where is Legionella?

According to HSG 274, any water system that has the right environmental conditions could potentially be a source for legionella bacteria growth. There is a reasonably foreseeable legionella risk in your water system if:

How it spreads?

Legionellae is normally transmitted when a person breathes in very small water droplets, that have been populated by the Legionella bacteria. The droplets (aerosol) must be of a size that can pass into the lungs.

Managing the risk

The following precautions should be considered (HSG 274):


In HSG 274 Chlorine Dioxide is mentioned as an effective disinfectant (when applied correctly) at controlling both legionella and biofilm growth in hot and cold-water systems.

Chlorine dioxide can be dosed continuously or intermittently.

Continuous dosing: 0.1-0.5 mg/L. Where the water is intended for human consumption the combined concentration of chlorine dioxide, chlorite and chlorate in the water entering supply do not exceed 0.5 mg/l as chlorine dioxide.

Shock dosing: 20-50mg/L. The system should be flushed through thoroughly after cleaning.
