Water hygiene is a fundamental part of building management, and for facilities managers, it represents a significant and ongoing responsibility. Ensuring that water systems are safe, compliant, and properly maintained is not just a matter of best practice it is a legal obligation that directly impacts the health and safety of building occupants.
From controlling the risk of Legionella bacteria to maintaining detailed compliance records, facilities managers play a central role in protecting people, properties, and organisations from potentially serious consequences.
What Is Water Hygiene?
Water hygiene refers to the processes and procedures used to ensure that water systems remain clean, safe, and free from harmful bacteria. In any building where water is stored, circulated, or used, there is a potential risk of microbial growth, particularly in systems that are poorly maintained or infrequently used.
One of the most significant risks comes from Legionella bacteria, which can develop in stagnant water or in systems where temperatures are not properly controlled. When contaminated water droplets become airborne and are inhaled, they can cause Legionnaires’ disease, a serious and sometimes fatal form of pneumonia. Because of this, maintaining high standards of water hygiene is essential in all types of commercial and residential properties.
Legal Responsibilities for Facilities Managers
In the UK, water hygiene responsibilities are governed by a framework of health and safety legislation. Facilities managers are often considered the “responsible person” or act on behalf of the duty holder, meaning they are directly involved in ensuring compliance with legal requirements.
These responsibilities are primarily defined under the Health and Safety at Work etc. Act 1974, the Control of Substances Hazardous to Health (COSHH) Regulations, and the HSE’s Approved Code of Practice L8 (ACoP L8). Together, these regulations require that risks are properly identified, assessed, and controlled, and that appropriate systems are in place to prevent harm.
In practical terms, this means facilities managers must ensure that water systems are assessed for risk, that control measures are implemented and maintained, and that accurate records are kept. Failure to meet these obligations can lead to enforcement action, including fines, prosecution, and significant reputational damage.
Conducting Legionella Risk Assessments
A Legionella risk assessment forms the foundation of any effective water hygiene strategy. Facilities managers must ensure that a suitable and sufficient assessment is carried out by a competent person who understands the complexities of water systems and the factors that contribute to bacterial growth.
This process involves a thorough review of the entire water system, including tanks, pipework, outlets, and any associated equipment. The aim is to identify areas where water may stagnate, where temperatures fall within the range that encourages bacterial growth, or where there are structural issues that increase risk.
Risk assessments should not be treated as a one-off task. They must be reviewed regularly, particularly when there are changes to the system, the building’s usage, or after periods of low occupancy. Keeping assessments up to date is essential for maintaining compliance and ensuring ongoing safety.
Implementing Control Measures
Once risks have been identified, appropriate control measures must be put in place to minimise them. This is a critical step, as simply identifying a risk without taking action does not meet legal requirements.
Control measures often focus on maintaining water temperatures outside the range in which Legionella bacteria thrive, ensuring regular water movement throughout the system, and removing or modifying any redundant pipework that could allow water to stagnate. In some cases, cleaning and disinfection of tanks and systems may also be required.
Facilities managers must ensure that these measures are not only implemented but also consistently followed. This often involves coordinating with maintenance teams or external contractors to ensure that all actions are carried out correctly and on schedule.
Ongoing Monitoring and Maintenance
Water hygiene management is an ongoing process that requires regular monitoring and maintenance. Facilities managers must ensure that systems are routinely checked to confirm that control measures remain effective and that no new risks have developed.
This typically involves monitoring water temperatures, inspecting tanks and infrastructure, and ensuring that infrequently used outlets are flushed regularly to prevent stagnation. In higher-risk environments, additional measures such as water sampling may be required to verify system safety.
Without consistent monitoring, even well-designed control measures can fail over time. Regular oversight ensures that issues are identified early and addressed before they become serious problems.
Record Keeping and Documentation
Maintaining accurate and up-to-date records is a crucial part of demonstrating compliance with UK regulations. Facilities managers must ensure that all aspects of water hygiene management are documented clearly and comprehensively.
This includes keeping copies of risk assessments, logs of monitoring activities, maintenance records, and details of any corrective actions taken. A written scheme of control should also be in place, outlining how risks are managed and who is responsible for each task.
These records not only support internal management but may also be required during inspections or audits. In the event of an incident, they can provide essential evidence that appropriate steps were taken to manage risk.
Managing Contractors and Specialist Support
In many cases, facilities managers rely on external specialists to support water hygiene compliance. This may include companies that carry out Legionella risk assessments, water testing, or system maintenance.
While these services can provide valuable expertise, the responsibility for compliance does not transfer entirely to the contractor. Facilities managers must ensure that any external providers are competent, properly qualified, and working in line with current regulations.
It is also important to review any reports or recommendations provided and ensure that required actions are completed. Effective contractor management is key to maintaining a safe and compliant water system.
Why Professional Support Matters
Managing water hygiene can be complex, particularly in larger or older buildings where systems may be more difficult to assess and maintain. Facilities managers are often balancing multiple responsibilities, and without specialist knowledge, it can be challenging to identify all potential risks.
Professional Legionella compliance services provide an added layer of assurance by bringing technical expertise and experience. They can help identify issues that may otherwise go unnoticed, ensure that assessments meet regulatory standards, and provide clear guidance on maintaining compliance over time.
This support not only reduces risk but also helps facilities managers feel confident that they are meeting their legal obligations.
