Cooling Tower Risk Management Plan Reviews and Audits


Poor management of cooling tower systems increases the potential for the growth of Legionella within the system, which can give rise to an outbreak of Legionnaires’ disease, a serious and potentially life threatening form of pneumonia.  Cooling tower systems can therefore pose a significant liability for Property Owners and Managers that requires a robust risk management approach to ensure that this risk is adequately controlled.

The legislation governing the operation of cooling towers is state/territory-based and as a result, the legislative requirements vary between states and territories. Typically the legislation relating to cooling towers forms part of Public Health related legislation, due to the potential for the operation of cooling towers to represent a public health risk.  The Australian and New Zealand Standard AS/NZS3666, Air Handing and Water Systems of Buildings – Microbial Control provides additional guidance on the appropriate design, operation, maintenance and risk assessment of a cooling tower system.
