Why does a cooling tower need a qualified chemist?

Cooling towers are one of the highest-risk water systems in any industrial or commercial facility. Poorly managed water chemistry creates the conditions for Legionella growth, accelerated corrosion and scale buildup that degrades efficiency, shortens equipment life and poses a risk to human health.

We don't just run routine tests. We interpret what the chemistry is telling us about your system's condition, adjust dosing programs in response to changing conditions, and identify problems before they become compliance failures, unplanned shutdowns or public health incidents.

We also prepare Legionella risk management plans, the foundation of every compliant cooling tower in NSW, so your plan, your testing and your treatment program all come from the same qualified source.

For any facility running a cooling tower, the question isn't whether you need that level of expertise. It is whether you currently have it.

What does cooling tower water treatment include?

Supierz Water can:

• Prepare your Legionella risk management plan (RMP), and review it as your system or regulations change.
• Meet your compliance obligations, including testing, monthly Form 3 reports and documentation.
• Conduct site visits to undertake sampling, testing and chemical dosing.
• Manage and adjust your dosing regimen.
• Review laboratory results and undertake urgent remedial response if needed, in accordance with regulatory obligations.
• Decontaminate and disinfect cooling towers when required.
