Cooling Water Systems and Warm Water Systems

Regulated systems are cooling water systems and warm water systems. 

The Public Health Act 2010 sets out parameters in governing regulated systems in order to safely manage and prevent the growth and transmission of Legionella bacteria.  Legionella bacteria cause Legionnaire’s disease and can be a life-threatening condition. 


Registration of Cooling Water Systems and Warm Water Systems

It is a legal requirement for all owners and/or occupiers of buildings who install and operate a cooling water system or warm water system (regulated system) to notify Georges River Council under s31 Public Health Act 2010.

Registration could also include any changes to the system when any of the following occurs:

  • a new system is installed on a premises
  • there is a change of owner or occupier for a building on which a system is located
  • the system is modified (for example, cooling towers added or removed)
  • the contact details for the building manager changes
  • the system is decommissioned.

To register or update information regarding your regulated system please complete our Public Health Registration Form.
