Water treatment log books are used at sites to record and closely monitor information relating to your water supply. As well as being best practise for Health & Safety, they are also used to communicate to site staff the importance of water hygiene and control measures, as well as record roles and responsibilities.

Uses of a Water Treatment Log Book

Log books tend to be the joint responsibility of your staff on-site and your water treatment provider, such as Opal.

It should be completed regularly to keep track of your compliance tasks to evidence your maintenance schedule. Depending on your site’s requirements, there are several activities that you can record in this document:

  • Temperature monitoring
  • Shower head cleaning and descaling
  • Flushing
  • Inspections
  • Servicing

Along with this we will provide you with a document covering contract management which shows schedule and responsibilities and what tasks your service contract includes. We prefer to break it down to ensure that every step is accounted for and lines of responsibility are clearly defined.

The logbook will contain information on when the legionella risk assessment review is due and records of legionella awareness training.

As well as keeping a record for internal monitoring and safety, your log book is evidence that you carried out essential water safety tasks if a Health & Safety inspector asks to see proof.

Updating your Water Treatment Log Book

Your log book should be updated and reviewed regularly. At Opal, we hold regular customer meetings and review your log book with you, ensuring that checks are being recorded and the correct worksheets are being signed.

We recommend that a copy of the building’s risk assessment and schematic are kept with the log book.
