What is
Legionnaires' Disease?

Legionellosis is a collective term for diseases caused by legionella bacteria including the most serious Legionnaires’ disease, as well as the similar but less serious conditions of Pontiac fever and Lochgoilhead fever. Legionnaires’ disease is a potentially fatal form of pneumonia and everyone is susceptible to infection.

Are there Legionella risks in my workplace?

Any water system, with the right environmental conditions, could be a source for legionella bacteria growth. There is a reasonably foreseeable legionella risk if your water system:

  1. has a water temperature between 20–45 °C
  2. creates and/or spreads breathable droplets, eg aerosol created by a cooling tower, or water outlets
  3. stores and/or re-circulates water
  4. likely to contain a source of nutrients for the organism to grow, eg rust, sludge, scale, organic matter and biofilms

The most common sources of legionella are in man-made water systems including:

Cooling Towers & Evaporative Condensers
Hot & Cold Water Systems
Spa & Swimming Pools


We provide expert management and chemical analysis services and products for the following water treatment plant:

Cooling Towers

A cooling tower is a device that rejects waste heat to the atmosphere through the cooling of a coolant stream, usually a water stream to a lower temperature.

Steam Boilers

A steam boiler system distributes heat via steam. The boiler furnace heats the water with a gas or oil burner, and the water is turned into steam.


Heating and cooling installation use water for the energy transfer because it’s the most cost effective medium and most readily available, stable resource.
