Understanding National Water Hygiene EUSR Registration: What it covers and who needs it

One key requirement for many professionals working on the UK water supply is holding a valid National Water Hygiene EUSR Registration. Whether you’re entering the industry or ensuring your team stays compliant, understanding this essential certification – often referred to as the “blue card” – is critical.

In this blog, we explore what the EUSR Water Hygiene registration is, who needs it and what is meant by “Restricted Operations”.

What is the National Water Hygiene Scheme?

The National Water Hygiene Scheme, administered by EUSR, was introduced to protect public health and ensure safe working practices within the water industry.

This scheme ensures that all personnel working on the clean water network understand the importance of hygiene, safety and protecting the integrity of the water supply.

Upon successful completion of the training and assessment, individuals are registered on the EUSR and issued with the recognisable “blue card”, valid for three years.

What are “Restricted Operations”?

“Restricted Operations” refer to activities that could introduce contamination into the public water supply. If your role involves any of the following, EUSR Water Hygiene registration is mandatory:

• Accessing treated water sites, such as service reservoirs, water treatment works or pumping stations
• Working on or around potable water mains and water service pipes
• Sampling or handling water for human consumption
• Connecting properties or networks to the clean water system
• Working in environments where you may come into contact with drinking water infrastructure

Essentially, if your work brings you near the distribution and supply of treated drinking water, you are likely carrying out restricted operations and you’ll need a valid EUSR Water Hygiene registration to do so legally and safely.

Who needs EUSR Water Hygiene Registration?

The EUSR Water Hygiene “blue card” is required for a wide range of job roles in the water sector, including but not limited to:

1. Water company employees
2. Subcontractors working on clean water networks
3. Utility operatives, technicians and engineers
4. Site visitors and supervisors accessing treated water facilities
5. Leakage technicians and mains rehabilitation teams

Employers across the water industry are responsible for ensuring that staff and contractors working on restricted operations hold this certification. It’s also a key requirement under water company hygiene codes of practice and Water UK guidance.
