The success of any management system depends on knowing the facts and having the most relevant information at hand. Risk mitigation and duty of care go hand in hand in the world of Legionella management. Therefore knowing and understanding your cold and hot water infrastructure is paramount. If you know your system, you understand where the risks are.  To understand the information well enough to make pertinent decisions relating to water risk management to control the Legionella is required. Specialised training may be required by the staff involved in the water risk management committee along with the contractors involved to ensure pertinent decisions and actions are put into place.

Combating Legionella and Pseudomonas is a crucial part of managing, operating and maintaining any water system. Since hot and cold water systems along with warm water systems are used extensively throughout hospitals, health care facilities and residential aged care, plus many others, it is a good idea to make use of all the help and information you can get if you have responsibility for dealing with the challenges such engineered water systems can present.

Duty of care would dictate that operations and infrastructure management, clinical directors, managers and staff, and various maintenance contractors would benefit greatly from the knowledge gained in undertaking training in the following areas:-


  • Understanding Legionella and what it is
  • Who is most at risk from the bacteria and how it is contracted

  • Water supply quality factors

Risk Assessment

  • The Enhealth document explained
  • Water Risk Management explained
