Industries › Commercial HVAC & Facilities
Cooling tower maintenance, uptime and compliance for hospitals, universities and commercial buildings.
For a university, hospital or government building, the cooling tower is both an uptime risk and a compliance obligation. It has to keep the building cool, and it has to satisfy AS/NZS 3666 and Queensland public health requirements every time it is audited.
Eureka Water & Filtration maintains, refurbishes and documents commercial thermal plants across Queensland, so facilities managers can answer both with one service record.
Facing a compliance audit?
We carry out cooling tower Legionella auditing in Brisbane and across North Queensland, and supply a full compliance pack at handover.
Facilities we maintain
Hospitals and health
Highest-risk sites
What matters
Legionella risk management, records ready for audit, and work planned around patient areas.
Universities and campuses
Multi-tower sites
What matters
Staged refurbishment programs that fit annual maintenance budgets.
Commercial and government
Offices, centres and accommodation
What matters

Cooling tower maintenance and services for commercial facilities
Structural overhauls, fill, motors, drives and drift eliminators.
Legionella auditing, water sampling and reporting.
Plates, gaskets, descaling and rebuilds for building services.
Fill, drift eliminators and heat exchanger parts from Townsville.
Working in occupied buildings
Most of our commercial work happens while the building stays open.
Shutdowns planned around occupancy and peak cooling demand
Isolation, lockout and access management under a site-specific SWMS
Contractor inductions completed before work starts
Noise, access and work areas agreed with your facilities team
Legionella sampling results and a summary of work completed
Cooling towers and chiller plant
Cooling towers reject heat from a building’s chiller plant through the condenser water loop, so a tower problem quickly becomes a cooling problem. These are commercial cooling towers and plant rooms from recent work.
How a staged refurbishment program works
Fleet inspection
Every tower assessed, with a prioritised condition report.
Program and budget
Refurbishment staged across your towers and maintenance years.

Commercial facilities FAQs
What do Queensland facilities need to do to manage Legionella in cooling towers?
Cooling tower owners are responsible for managing Legionella risk, and requirements vary by facility and local council. In practice that means regular cleaning and maintenance, water treatment, sampling and good records, in line with AS/NZS 3666. We can audit your towers, carry out the maintenance and refurbishment work, and help you keep the records you need.
Can you refurbish towers while the building stays open?
Yes. We plan shutdowns around occupancy, with isolation, lockout and access management under a site-specific SWMS.
Can a site spread refurbishment over several years?
Yes. We run staged programs across a tower fleet so the work fits annual maintenance budgets, as we did on a 5-tower site.
What records do you provide for audits?
Legionella audit findings and sampling results, plus a summary of the refurbishment work completed.
Do you work in Brisbane?
Yes. We carry out cooling tower Legionella auditing in Brisbane, as well as maintenance and refurbishment across North Queensland.
What does cooling tower maintenance include?
Regular inspection, cleaning and disinfection, water treatment checks and Legionella sampling, plus checking the fill, drift eliminators, motors and drives. Worn components are repaired or replaced, and every visit is recorded for your audit file.
How often does a cooling tower need maintenance?
AS/NZS 3666 sets out what routine servicing involves, and the schedule should come from your site’s risk assessment. In Queensland, the owner of an air-conditioning cooling tower must have it maintained and inspected by a competent person. WorkSafe Queensland’s guide to Legionella control in cooling water systems covers what that involves.
Do you supply cooling tower parts?
Yes. We supply fill, drift eliminators and heat exchanger parts from Townsville, and fit them as part of maintenance or refurbishment work.
Facing an audit or an ageing tower?
Whether you are preparing for an AS/NZS 3666 audit, planning a shutdown around occupancy, or budgeting a staged refurbishment, we can help.
