Water Management

Legionnaires Disease – The control of legionella bacteria in hot and cold water systems.

In the UK we have very high drinking water standards, but unfortunately any water system that has the right environment conditions could potentially be a source for legionella bacteria growth. There is a reasonably foreseeable legionella risk in your water system if:

  • Water is stored or re- circulated as part of your system
  • The water temperature in all or some part of the systems may be between 20-45°C
  • There are deposits that can support bacterial growth, such as rust, sludge, scale and organic matter
  • It’s possible of water droplets to be produced and , if so, they can be dispersed
  • It’s likely that any of your employees, contractors, visitors etc could be exposed to any contaminated water droplets

Where do I stand legally with regards my water systems?

The below statement has been taken from the HSE’s Acop L8 document


Approved Code of Practice

This Code has been approved by the Health and Safety Executive, with the consent of the Secretary of State. It gives practical advice on how to comply with the law. If you follow the advice you will be doing enough to comply with the law in respect of those specific matters on which the Code gives advice. You may use alternative methods to those set out in the Code in order to comply with the law.

However, the Code has a special legal status. If you are prosecuted for breach of health and safety law, and it is proved that you did not follow the relevant provisions of the Code, you will need to show that you have complied with the law in some other way or a Court will find you at fault.
