To protect the UK's drinking water, every professional working on the water supply network must have the highest standards of hygiene knowledge. The cornerstone of this standard is the EUSR Water Hygiene Card, a certification that proves competence and commitment to public health.

Often called the 'Blue Card', this qualification is essential for anyone whose work brings them into contact with potable water. This guide provides a complete overview of the EUSR water hygiene card, explaining what it is, who requires it, and the simple steps to obtaining yours.

What is an EUSR Water Hygiene Card?

The EUSR Water Hygiene Card is a certification managed by the Energy & Utility Skills Register (EUSR). It serves as official proof that the holder has been successfully trained in the best practices required for working safely with drinking water, preventing contamination, and protecting public health.

The scheme ensures a consistent, industry-wide standard is met by all workers. Holding a valid EUSR water hygiene certification demonstrates a comprehensive understanding of critical hygiene issues and confirms your ability to work on restricted water operations sites.

Who Needs an EUSR Water Hygiene Certification?

If your job involves working on or near the public water supply, you will need an EUSR Water Hygiene Card. It is a mandatory requirement for gaining access to restricted sites, including pumping stations, water treatment works, and service reservoirs.

This includes professionals in roles such as:

  • Water company operatives and contractors

  • Plumbers, and mechanical and electrical engineers

  • Construction and utility workers

  • Anyone involved in the commissioning, maintenance, repair, or inspection of water infrastructure

In short, if your work could in any way impact the quality of drinking water, securing an EUSR water hygiene certification is a fundamental requirement for your role.

Why is the EUSR Water Hygiene Scheme so Important?

The scheme is a critical component of the UK's public health strategy, safeguarding our water from contamination and waterborne diseases.

  1. Upholding Public Health: The primary objective is to keep drinking water safe. The training covers all aspects of hygiene, from personal conduct to the correct handling of tools, ensuring every action protects the water supply.

  2. A Recognised UK Standard: The EUSR water hygiene card provides a single, trusted standard across the UK. It guarantees that every certified individual possesses the same essential knowledge.

  3. Essential for Site Access: UK water companies mandate the Blue Card for entry to restricted sites. Without a valid EUSR water hygiene card, you will be denied access, making it indispensable for your career.
