Cooling towers and warm water systems are regulated systems according to the Public Health Act 1997 (external link).
A cooling tower is a device that lowers the temperature of water by evaporative cooling in which atmospheric air is in contact with falling water, thereby exchanging heat. In other words, it is a device that uses the air around it to cool down a stored amount of water.
A warm water system is a system that stores water between 30–50˚C. These systems can be found at a variety of places, such as hospitals and nursing homes.
Registration of regulated systems
Cooling towers and warm water systems must be registered with Council.
If you have not done so already, please complete the Regulated Systems Registration Application form (PDF). A registration fee applies (PDF).
The State Government has also published Guidelines for Control of Legionella in Regulated Systems (PDF).
As part of your registration, you are required to undertake regular water sampling of the system as detailed in the AS/NZS 3666.3:2011.
