NSW Legionella Regulations set to change in 2017

On Friday 1 December 2017, the NSW Health Minister introduced regulations requiring:

  • Monthly testing for Legionella and Heterotrophic Colony Count (HCC) of all cooling tower systems in NSW from 1 January 2018
  • Reporting of any test results that exceeds 1,000 CFU/mL Legionella or 5,000,000 CFU/mL HCC to the Local Government by the occupier of premises on which the cooling tower is installed

These changes are two of the six recommended improvements to the existing regulations made by the Expert Panel and Legionella Steering Committee established by NSW Health in July 2016.
