Role of the Authorised Person - Operations

Course Overview

Our Authorised Persons training course supports those with the day to day operational responsibility of water systems and is accredited with CPD and recognised by ILM, part of the City & Guilds Group.

The Authorised Person (AP) has operational responsibility for the water service. They will be qualified, sufficiently experienced and skilled to fully operate the service, including its maintenance. This role involves maintenance of records, quality of service and system safety (integrity). The AP oversees the routine testing of the water, storage and distribution system. The AP establishes and maintains the roles and validation of CP's (Competent Persons), who may be employees or appointed contractors.

The training course is of vital interest for all individuals who are responsible for the management of Legionellosis and particularly those who are involved in the design, operation, monitoring and maintenance of building water systems. 

We will provide the AP with a thorough understanding of the risks posed by Legionella and explore the key requirements for design, operation, monitoring and maintenance of water systems to control such risks.

Topics covered on the course will include:

  • The requirements for growth of Legionella, interactions of Legionella with other microbiota
  • Factors affecting the accumulation of biofilm
  • Effectiveness of biocides against Legionella, protozoa and biofilm
  • When to use biocides, selection of biocides
  • Effectiveness of temperature as a Legionella control method
  • Cold and hot water storage design and upgrading, distribution system issues
  • Showers, disposable and re‐usable shower head filters.
  • Discuss the design of other water systems and learn how to monitor, maintain and operate such systems. Including e.g. spa baths, hydrotherapy pools, decorative fountains, etc.
  • Monitoring, Legionella sampling.
