Cooling tower requirements

Registration Requirements

Legislation requires that all water-cooling towers and warm-water systems installed within the Campbelltown Local Government Area be registered with Council due to the potential health risks of Legionnaires’ Disease.

The Regulated System (Water Cooling/Warm Water System) Registration Form(172KB, PDF) is to be used by businesses wanting to register their cooling towers /warm water system or to change any registration details. NSW Health’s Code of Practice for the Control of Legionnaires’ Disease explains the legislative requirements for microbial control and outlines common and accepted practices to minimise the transmission of Legionnaires’ Disease through hazard minimisation in air handling systems, water cooling systems, hot and warm water systems and evaporative coolers.

There are over 50 cooling towers within the City of Campbelltown and these systems are mainly used in association with commercial air conditioning systems and factory processing equipment. Legislation requires that the operators of these types of systems follow specific operation and maintenance procedures to minimise the likelihood of Legionnaires’ Disease.

Operation and Maintenance Requirements

Water-cooling towers must be maintained in accordance with AS/NZS 3666.2 “Air-Handling and Water Systems of Buildings - Microbial Control, Part 2; Operation and Maintenance”. 

This standard requires that systems:

  • Be inspected by trained technicians at least monthly.
  • Be cleaned when necessary and at least every 6 months.
  • Be equipped with an approved process of disinfection.
     

Operation and maintenance manuals and maintenance records must be kept on site and be available for inspection by authorised persons on request.

Manuals must include:

  • Details of the plant, equipment and systems.
  • Recommended cleaning, disinfection and emergency decontamination procedures.
  • Details of the maintenance management program, inspections and servicing
     

Water Quality Monitoring

Council encourages regular water sampling of cooling towers to monitor the effectiveness of maintenance programs and disinfection equipment. Copies of these reports must be kept on site with the service records.

Council Inspections

Environmental Health Officers conduct annual audits and inspections of all registered systems to ensure that they are being properly maintained.
