Legionella Risk Assessments for Schools, Colleges & Universities

Specialist Water Hygiene Support for Education Premises

Schools, colleges and universities can present particular challenges for Legionella management.

Educational buildings often contain a mixture of classrooms, teaching blocks, sports facilities, kitchens, laboratories, offices and welfare areas. Many also experience significant changes in water use during weekends, school holidays and other periods of reduced occupancy.

Without suitable management, these changes in use can create conditions where water stagnation becomes a concern.

Source Water Compliance provides independent Legionella risk assessments and water hygiene consultancy for schools, colleges, universities and other education premises.

We help estates teams, facilities managers, responsible persons and education providers understand their water systems and establish practical, proportionate control measures.


Why Education Premises Need Careful Water Management

One of the biggest water hygiene challenges within education is changing occupancy.

During term time, many outlets may be used frequently. During holidays, however, entire teaching blocks, washrooms, showers or other areas may receive little or no water use for several weeks.

This can increase the potential for stagnation within sections of the system.

Typical education premises may contain:

  • Cold water storage tanks
  • Calorifiers and central hot water systems
  • Hot water circulation systems
  • Classroom wash hand basins
  • Student and staff toilets
  • Sports changing rooms
  • Showers
  • Kitchens and catering facilities
  • Science laboratories
  • Design and technology areas
  • Staff rooms
  • Medical or first-aid rooms
  • Nursery facilities
  • Boarding accommodation
  • External taps
  • Thermostatic mixing valves
  • Point-of-use water heaters
  • Expansion vessels
  • Water softeners
  • Low-use and seasonal outlets

A suitable assessment therefore needs to consider not only the equipment present, but how different parts of the site are used throughout the academic year.


Education Legionella Risk Assessments

Our assessments involve a detailed inspection of the hot and cold water systems together with a review of the existing arrangements for managing Legionella risk.

Depending on the premises, this may include:

Incoming Water Supplies

Identification of incoming mains supplies and how water is stored and distributed across the site.

Cold Water Storage

Inspection of cold water storage tanks including condition, temperatures, turnover, configuration and associated distribution pipework.

Hot Water Systems

Assessment of calorifiers, hot water generators, circulating systems and point-of-use water heaters.

Showers and Sports Facilities

Review of shower facilities within sports halls, changing rooms, boarding accommodation and other areas where aerosols may be generated.

Low-Use Outlets

Identification of outlets and areas that may experience poor water turnover.

Particular consideration may be given to:

  • Spare classrooms
  • Unused toilet blocks
  • Little-used showers
  • Vacant buildings
  • Temporary teaching areas
  • Remote sections of the site
  • Seasonal facilities
  • Areas awaiting refurbishment

Water Temperatures

Representative temperature measurements can be taken throughout the system to assess the effectiveness of existing temperature control arrangements.

Where temperature is used as the principal control measure, HSG274 Part 2 provides technical guidance for hot and cold water systems as part of the wider Legionella control framework.

System Configuration

The assessment can identify conditions that may increase risk, including:

  • Dead legs
  • Dead ends
  • Redundant pipework
  • Poor hot water circulation
  • Excessive pipe runs
  • Heat gain into cold water
  • Low water turnover
  • Inappropriate pipework alterations

Water Hygiene Management

Available documentation can also be reviewed, including:

  • Previous Legionella risk assessments
  • Written Schemes of Control
  • Temperature monitoring
  • Flushing records
  • Tank inspections
  • Shower cleaning records
  • TMV servicing
  • Cleaning and disinfection records
  • Sampling results
  • Corrective actions
  • Roles and responsibilities

HSE guidance requires those responsible for premises to identify and assess sources of Legionella risk, manage and control those risks, monitor precautions and maintain appropriate records.


Managing the Risk During School Holidays

Periods of reduced occupancy are particularly important within education premises.

During summer holidays, half terms, Christmas closures and other shutdown periods, normal water use can reduce significantly.

A classroom basin or shower that is used regularly during term time may suddenly remain unused for several weeks.

A suitable water hygiene programme should therefore consider how water systems are managed before, during and following periods of reduced use.

This may include reviewing:

  • Holiday flushing arrangements
  • Little-used outlets
  • Shower facilities
  • Closed teaching blocks
  • Boarding accommodation
  • Seasonal buildings
  • Temporary shutdowns
  • Recommissioning before pupils and staff return

Simply having a flushing programme is not enough — it should reflect the actual water system, frequency of use and findings of the Legionella risk assessment.


Large and Multi-Building Education Sites

Education estates can also be surprisingly complex.

A school or college campus may contain buildings constructed at very different times, each with separate water systems or different methods of generating hot water.

A typical site might include:

Main teaching building → sports centre → sixth-form block → nursery → science building → workshop → catering facility → temporary classrooms

Older buildings may also have been modified repeatedly as rooms change purpose.

Our assessment considers the estate as a complete water system while identifying differences between individual buildings and areas.


Sports Halls, Changing Rooms and Showers

Sports facilities deserve particular consideration because showers can generate aerosols and may experience significant variation in use.

For example, showers may be heavily used during term time but receive very little use during holidays or examination periods.

Assessments can consider:

  • Shower usage
  • Water temperatures
  • Cleaning arrangements
  • Showerhead condition
  • Flushing
  • Hot water circulation
  • TMVs
  • Little-used changing areas
  • Seasonal usage

This helps ensure sports facilities are considered as part of the wider water hygiene strategy rather than treated separately from the rest of the estate.


Special Schools and Higher-Support Education Settings

Some educational establishments support pupils or students with complex physical or medical needs.

In these environments, the risk assessment should take account of the people using the building as well as the water system itself.

Facilities may also differ from conventional schools and can include:

  • Assisted bathrooms
  • Specialist hygiene facilities
  • Therapy areas
  • Accessible showers
  • Hydrotherapy or specialist equipment
  • Residential accommodation
  • Medical or nursing areas

Where these facilities are present, the scope of assessment should reflect their actual use and the needs of the people potentially exposed.

HSE guidance for education similarly stresses that health and safety management should reflect the real risks and the individual needs of students rather than relying on blanket approaches.


Practical Recommendations — Not Just a Report

Our reports provide clear, prioritised recommendations based on what is identified during the assessment.

These may include:

  • Improving hot water temperature control
  • Investigating excessive cold water temperatures
  • Reviewing holiday flushing arrangements
  • Improving hot water circulation
  • Removing redundant pipework
  • Reviewing little-used showers
  • Cleaning or maintaining cold water storage tanks
  • Servicing thermostatic mixing valves
  • Improving monitoring documentation
  • Reviewing responsibilities
  • Updating the Written Scheme of Control
  • Further investigation or sampling where appropriate

The objective is to provide practical actions that estates and facilities teams can realistically implement.


Working in Accordance With Legionella Guidance

Our education risk assessments take account of applicable guidance including:

HSE Approved Code of Practice L8 – Legionnaires’ disease

HSG274 Part 2 – The control of legionella bacteria in hot and cold water systems

HSG274 is intended to assist dutyholders, including employers and those in control of premises, with their legal duties relating to Legionella risk.
