What is Legionnaires disease?
Legionnaires disease is an illness caused by the inhalation of Legionella. Legionella is found in moist environments and becomes a problem when dispersed into the air as an aerosol. Water cooling systems used to cool the air in large buildings need to be monitored to control Legionella.
Role of Council
Wagga Wagga City Council maintains a register of cooling towers and warm water systems within its area. Routine inspections and audits of all registered cooling towers and warm water systems are undertaken by authorised officers to ensure systems are installed, serviced and maintained in accordance with the law. The proper installation, maintenance and cleaning of systems is a legal requirement under the Public Health Act 2010 and Public Health Regulation 2012.

Responsibilities of building owners and occupiers
The information contained in this section is for building managers who are responsible for maintaining water cooling systems. Building owners or occupiers are responsible for ensuring that the cooling tower or warm water system within your building is installed, maintained and operated in accordance with the law. All water-cooling systems can only be operated if they are equipped with a process designed to control microbial growth certified annually by a competent person and only if the process is in continuous operation.
If you have a cooling tower or warm water system, please ensure that your system is registered. If you are installing a new system, please complete the registration form below and return to Council.
Further information on legislative requirements on the installation, operation and maintenance of regulated systems may be obtained on NSW Health's website.
