Water Cooling Tower Requirements
Registration Requirements
Legislation requires that all water-cooling towers and warm-water systems installed within the Weddin Local Government Area be registered with Council due to the potential health risks of Legionnaires’ Disease.
The Cooling Tower Registration Form is to be used by businesses wanting to register their cooling towers or to change any details that have been registered. NSW Health’s Code of Practice for the Control of Legionnaires’ Disease explains the legislation 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.
Cooling tower 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:
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:
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.
