Legionella Control

It’s tragic but true: contamination of hot or cold water systems can cause a serious risk to health including:

  • Typhoid
  • Dysentry
  • Infective Jaundice
  • Gastroenteritis
  • Persistent Diarrhoea
  • Hepatitus A
  • Weil’s (Leptospirosis)
  • Legionellosis

Legionella bacteria occur naturally in rivers and lakes, but in such small amounts that they are not a hazard. In purpose-built water systems, however, conditions can occur that enable their rapid growth – and this can be a major health problem.

It’s a legal obligation under the Health and Safety at Work Act, 1974 for all employers in the UK to secure the welfare of persons at work. This includes the maintenance of plant and systems.

This is where we can help, by carrying out a survey of plant and systems areas where there is a heightened risk of Legionella bacterial growth. We can recommend remedial measures to clients and carry out work if required. This might include removal of ‘dead-legs’, cleaning of cold-water storage tanks or sterilisation of a water system.

Monitoring and recording of procedures is also important, not least because it can highlight a change in conditions such as water temperature, but also to show that clients are engaging with their legal responsibility.
