Achieving success in your cooling tower audit 

Tim Brumby Risk Consultant, HydroChem

A requirement of the NSW Public Health Regulations 2012 is for the occupier or a duly qualified person (DQP) to provide concise documentation to the auditor.  This includes the risk management plan (RMP) for each cooling water system (Approved Form 1), twelve monthly reports (Approved Form 3) and any relevant notifications made to local government authorities (Approved Form 4). Your audit will address compliance with the regulations and your RMP.

Tim, a recently appointed NSW Health approved auditor, will take you through the regulatory and scientific basis of recommendations typically contained within RMPs, and discuss key requirements to achieve a successful outcome in your audit.

Tim Brumby is a water risk management specialist who has provided advisory services in microbial risk and corrosion control for water systems at health, industrial, commercial, retail and institutional properties for over ten years. Prior to joining HydroChem, Tim was employed by one of Australia’s leading health, safety and environmental consultancies, where he frequently provided advice relating to managing risks of pathogenic bacteria in built water systems.

Tim has developed and reviewed risk management plans (RMPs) for water systems including cooling tower systems throughout Australia. Tim is an approved auditor of risk management plans for cooling water systems in both New South Wales and Victoria.


The critical cooling tower issues that must be inspected to reduce risk

Darren Driscoll CEO, FlowMatrix

A critical factor to prevent Legionella outbreaks from cooling towers is the condition of internal components, such as obsolete, faulty or dirty drift eliminators; blocked or broken water distribution systems; no safe access to remove drift eliminators and to inspect the water distribution system; or dirty, fouled fill pack. Darren will share some invaluable insights behind the access hatch, and provide for efficient cooling tower inspections with a maintenance checklist.

With 33 years’ experience in the cooling tower industry, Darren Driscoll is the founder and Managing Director of two companies located in Sydney and Melbourne – FlowMatrix and Coolclean.  Coolclean focuses on cooling tower servicing, risk reduction and performance, while FlowMatrix specialises in cooling tower repairs and upgrades.

The companies provide cooling tower services to the commercial and industrial sectors and subcontract to water treatment companies, air conditioning contractors, refrigeration contractors and facilities managers.

For 33 years Darren has stressed the importance of correctly maintaining the critical components inside cooling towers for compliance and to reduce Legionella outbreaks. As he says, “People should not be getting sick”. He stresses that to protect the public, the critical components in all cooling towers must be maintained correctly – in accordance with government regulations and the manufacturer’s maintenance instructions. However, in Sydney today, many cooling towers remain a risk to public health.
