Cooling Towers

Water cooling systems are conducive to the growth of Legionella organisms which are capable, under the right conditions, of transmitting Legionnaires' disease. The occupier of a premise on which a cooling tower/s is located must ensure the system is installed, operated and maintained in accordance with the Public Health Act 2010 and Public Health Regulation 2012. Please refer to the NSW Health website for details on the owners and occupiers responsibilities.

Cessnock Council conducts annual inspections of cooling towers and their associated certification, cleaning and servicing records as part of a routine inspection program. Register your Cooling Tower

Council’s Environment Health Officer will assess the following:

  • Physical inspection of tower – water is clean (no build-up of sludge or other matter), drift eliminators installed and in good condition, no splash out or leakage evident, chemicals stored appropriately, tower located for easy and safe access;
  • System equipped with a continuous process of disinfection; annual certificate for disinfection process valid;
  • Maintenance Manual:  
  • Monthly servicing reports available for past 12 months;
    • Six monthly cleaning reports available for past 12 months;
    • Any microbiological analysis results (if sampling conducted);  
  • Operation manual:
    • Start up/shut down procedures;
    • Procedures for servicing and cleaning the system;
    • Material safety data sheets (MSDS) for all chemicals used;
