Treatments with water-Legionella and its impact

Legionella bacteria occur in surface water, ground water and aerated biofilms at the air-water interface. Very small numbers of Legionella join in water supply buildings and hydraulic equipment. Legionella can subsequently multiply to high numbers in cooling towers; evaporate condensers, air washers, humidifiers, hot water heaters, spas, fountains, car washing facilities, and plumbing equipment; Water testing laboratories have performed studies that, within a month, Legionella bacteria will increase from less than 10 per millilitre to more than 10,000 per millilitre of water sample.Have a look at Greenfield Water Solutions for more info on this.

How spread is Legionella?

Legionella infects a individual who contains such bacteria when they inhale aerosols (small particles that do not settle out of the air). The dispersal of legionella can stretch for at least 6 kilometres. Such bacteria are known to be routinely responsible for serious, at times fatal, epidemics of human pneumopathy. Any individual may be infected, and legionellosis is particularly severe in subjects at risk. Legionella is prevalent in the ecosystem, i.e. water-based surface waters, reservoirs, rivers and bacterial reserves are generally. These are also used in systems for the delivery of drinking water , i.e. hot water for sanitary purposes, cooling towers and public hotels, campsites, etc. Legionella doesn’t spread from person to person.

Causes of Sickness

Bacterial Legionella species cause Legionnaires’ disease. They ‘re gram negative (but poorly stained), strictly aerobic rods. Optimum conditions for legionellosis production combine soft water with a temperature of 35-40 ° C. Contamination is primarily by aerosolized species being inhaled.


Furthermore, risk management requires daily testing of water for Legionella in all its forms in industrial environment, hospital environment, natural environments and artificial water networks.

Legionella grows intracellularly in protozoa such as amoebas and in biofilms, making them very immune.

Is it possible for Hospitals to install decorative fountain?

Installation of decorative fountains is strictly prohibited in hospitals. The water fountains should be treated with disinfectants such as chlorine or bromide for buildings which do not have individuals at risk for pneumonia. Ultraviolet light can be powerful, too. Decorative fountains should be drained and washed at least twice a year or more regularly if algae or debris is visible.
