High-Risk Water Systems

High-risk water systems like cooling towers and spa pool systems require constant management to ensure they are free from Legionella bacteria

High-Risk Water Systems

If your business contains one of the following water systems, there may be a high risk of Legionella exposure.

  • A cooling tower
  • A wet and dry cooling system
  • An evaporation condenser
  • Cold water system
  • Showers
  • Spray taps
  • Fire sprinklers
  • Spa pool or jacuzzi
  • Steam room

Cooling towers are particularly high-risk, as aerosol created by cooling towers can create and spread breathable droplets of water containing Legionella bacteria. It is essential that employees, building residents and visitors with weaker immune systems are not exposed to contaminated water droplets.


If an individual breathes in contaminated water droplets, they may develop Legionnaires’ disease or Pontiac fever.

Here’s how we can help…
