Frequently Asked Questions
Thomson Environmental Services are Water Quality Engineers specialising in Legionella control, water hygiene and safe water system management. Our services include risk assessments, monitoring, sampling, cleaning and disinfecting, booster pump servicing and training.
If you are responsible for a building with a water system, you will need to prepare a Legionella risk assessment to identify potential risks and show that you are managing water safety properly. This applies to many commercial, residential and public buildings.
A Legionella risk assessment should be reviewed regularly and whenever there are changes to the water system, building use, occupancy, or management responsibilities. If the existing assessment is no longer valid, it should be updated.
The responsible person is the individual appointed to manage Legionella control and water hygiene duties for a building. They need to understand the risks, arrange suitable checks and keep appropriate records.
A monitoring contract can include regular temperature checks, visual inspections, outlet checks, record keeping, water sampling where required and clear reporting. The exact schedule depends on the building and its water system.
Water sampling may be needed as part of ongoing monitoring, after cleaning and disinfecting, following changes to a water system, after periods of low use, or where there are concerns about water quality or Legionella risk.
Cleaning and disinfecting may involve cleaning tanks, disinfecting pipework or treating parts of the water system where contamination, sediment, biofilm or hygiene issues have been identified.
