L8 Water Monitoring

The next step following the completion of a Legionella Risk Assessment

What Is Water Monitoring?

A Water Monitoring Programme may be the next step following the completion of a Legionella Risk Assessment depending on the risks identified in accordance with ACoP L8. A written, site specific Water Monitoring programme is intended to address any aspects of the water system and its operation that may allow for the colonisation of bacteria which may then be exposed to people both within the vicinity of your building and outside. The control regime should be specific to the water systems present within your ownership with all control measures intended at minimising the risks appointment to personnel competent to fulfil them.

Following the risk assessment a ‘Responsible Person’ will be appointed. They will be required to ensure water monitoring activities identified are completed, and records are kept.

Why Is Water Monitoring Required?

Water Monitoring is an essential aspect for compliance with ACOP L8 and HSG274It is also highlighted in ACOP L8: 2013 where it states: ‘For precautions to remain effective, the condition and performance will need to be monitored. The appointed responsible person should oversee and manage this. Or, where appropriate, an external contractor or an independent party’.Both HSG274 and ACOP L8 require that the following are completed:
· Check the performance of the system and its component parts
· Inspect accessible parts of the system for damage and signs of contamination
· Monitor the treatment or treatment regime to ensure that it continues to control the required standard
· Audit the existing site records system


What is Involved?

The actions involved in the monitoring, testing and inspection of water systems will be based on the types of water systems and the components within them.Under HSG274, an effective water monitoring programme for domestic hot and cold water systems should include:

· Temperature monitoring of water outlets, water heaters, cold water storage tanks and Calorifiers

· Showerhead and hose cleaning or replacement

· Maintenance of Thermostatic Mixing Valves

· Inspection of Cold Water Storage Units

· Inspection of Calorifiers

Water Log Books

Under requirements set out by HSG274, it is important that a method for effectively recording and storing the data gathered is established. It is also a requirement that this information is kept at for least five years.

EMS Water are able to provide paper based Water Hygiene Log-books for this purpose which ensures that all data is stored in a central place and kept up to date. We are also able to provide cloud-based software for this purpose. This is particularly useful for clients with large property portfolios and multi-site surveys.
