Start with the recommendation
An existing water hygiene report or control programme is a useful starting point. Send the relevant finding and its location rather than trying to convert it into a technical specification yourself.
Sampling: a defined water-sampling requirement
For Legionella sampling, describe why samples are requested and provide previous results or proposed locations if available. Agree the analysis and reporting arrangements as part of the scope. Discuss Legionella sampling ↗
Monitoring: checks within an existing programme
For temperature monitoring, share the points to be checked, current schedule and records. Include access arrangements and who should receive the readings. Explore temperature monitoring ↗
Disinfection: planned work on the system
For disinfection, describe the domestic or commercial hot and cold water services involved. Include the reason for the work and restrictions on isolation or water use. Discuss hot and cold water disinfection ↗
Several services can belong in one enquiry
The services are distinct, but a site may need more than one. Include the full recommendation so sampling, monitoring, tank work and any practical plumbing requirements can be discussed together.
