Legionella & Microbiological Risk Management
Find where the risk sits in your building's water systems, put controls in place, and prove they're working.
How Legionella Spreads in Buildings
Legionella spreads through fine water droplets: showers, cooling towers, spa pools and decorative fountains. Hotels and hospitals have all of them, often across many buildings.
Managing that risk isn't a single test. It's a plan: knowing which systems carry risk, setting control limits, checking them, and acting when something drifts.
Five Steps, One Water Management Program
Risk Assessment
Review system conditions and identify where Legionella growth and spread may occur.
Water Management Plan
Define control measures, operating limits, responsibilities and corrective actions.
Monitoring & Sampling
Set monitoring requirements and arrange sampling and laboratory testing in line with the plan.
Corrective Action
Support corrective measures, including cleaning and disinfection, based on findings and agreed limits.
Verification & Review
Check the plan is followed, assess whether controls work, and update the plan when required.
