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
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:
