Cooling Towers

Badly maintained cooling towers and warm water systems provide the ideal conditions in which Legionella bacteria can multiply to high numbers.

These systems may then spread the bacteria via tiny water droplets, which when inhaled can cause Legionnaires' disease – the infection can be fatal to individuals with weakened immune systems. For this reason legislation requires that owners and operators of such equipment must register the system with the local authority as well as operate and maintain them and keep appropriate records in accordance with legislative requirements.

The Public Health Act (2010) and the Public Health Regulation (2012) define the roles, responsibilities and basis for managing cooling water systems and other regulated systems in NSW: The regulatory approach for cooling water systems in NSW is based on the 2011 edition of the Australian/New Zealand Standard (AS/NZS) 3666 Parts 1, 2, 3 and 4.
