Why Choose CETEC 

CETEC has consulted in Legionella risk management for more than 30 years.

Since 2013, CETEC has provided Legionella risk management expertise and services to more than 100 hospital and other high risk sites.

Our Background

CETEC Principal Consultant, Dr Vyt Garnys convened and conducted Australia's first general industrial workshop on Legionella in 1987. 

In 2000, CETEC was contracted by the management of the Melbourne Aquarium to provide a solution to recurring Legionella in their cooling tower water system.  CETEC also participated in their experts review committee and from this event, key learnings were incorporated into the Victorian government developed 'best practice' Legionella guidelines for the risk management of cooling towers.

In 2013, CETEC was the lead Legionella consultant at The Wesley Hospital in Brisbane and subsequently was appointed by the Queensland Government to a Technical Advisory Panel (TAP) charged with developing the Guidelines for Managing Microbial Water Quality in Health Facilities.   

In 2014, a CETEC led consortium was engaged by the National Environmental Health Standing Committee (enHealth) to provide technical content for new national Guidelines for Legionella Control in the Operation and Maintenance of Water Distribution Systems in Health and Aged Care Facilities.  These guidelines were published in late 2015.
