Microbiological control of water
Variable temperatures, limited turnover, storage or extended shutdowns: an installation’s operation influences the conditions microorganisms encounter.
We support operators, hotels and domestic hot-water professionals in understanding these conditions and identifying suitable control measures.
Your installation under real operating conditions
The assessment considers the relevant circuit, its uses and operation, rather than temperature in isolation.
- Temperature profiles and changes over time.
- Residence time, stagnation, turnover and intermittent operation.
- Configuration, surfaces, biofilms and environmental conditions.
- Points of use and potential aerosol exposure.
In-depth expertise in Legionella
Our team draws on its available microbiological data to examine how operating conditions affect Legionella and compare relevant scenarios.
Where data and model validity allow, this assessment helps identify situations that may favour persistence or multiplication. It guides investigations and necessary verification without replacing installation monitoring.
Applications for operators and industry professionals
Hotels and buildings
Examine water and domestic hot-water networks, particularly under variable occupancy, recommissioning or recurring contamination.
Solar heating and domestic hot water
Study temperature profiles, storage and turnover while distinguishing sanitary water from the heat-transfer circuit.
Specific installations and uses
Define microbiological questions and monitoring points according to the equipment, uses and exposure routes actually present.
Recommendations suited to each circuit
Interpretation combines operating data, on-site observations and available results. A closed heat-transfer circuit is not treated as equivalent to a sanitary network that may expose users to aerosols.
You receive a summary of situations to investigate, assumptions, potential measures and a verification plan. Additional sampling, analysis or investigation is defined according to the mission and available capabilities. The aim is to reduce risk and verify measures over time, without promising total eradication.
Let’s discuss your installation
Describe your network, how it operates and the issue you face so we can define an initial approach.
