Ensuring the integrity and safety of the water supply is a fundamental responsibility for professionals working in the water industry. Whether you are a contractor, water company employee, or subcontractor, maintaining high standards of water hygiene is essential for public health and regulatory compliance. The National Water Hygiene (NWH) scheme, commonly referred to as the ‘Blue Card’, is a recognised industry standard developed by the Energy & Utility Skills Register (EUSR) to ensure that individuals working with clean water follow best practices.

Why Water Hygiene Training required?

UK water companies require all individuals involved in clean water operations—whether laying pipes, maintaining infrastructure, or accessing clean water sites—to hold a valid National Water Hygiene EUSR registration. This certification ensures workers meet the industry’s hygiene standards, helping businesses remain compliant with regulatory bodies and avoid penalties.

Waterborne diseases and contamination can have catastrophic consequences for both businesses and communities. Without proper hygiene training, the risk of bacterial contamination increases, potentially leading to serious health hazards. The National Water Hygiene scheme provides workers with the knowledge to prevent contamination and uphold the highest safety standards.

Companies operating in the water sector face significant financial and reputational risks if contamination occurs due to inadequate hygiene procedures. Implementing mandatory NWH training for all site personnel helps mitigate these risks, ensuring that employees understand and adhere to strict hygiene protocols.

Trained employees contribute to smoother, more efficient operations by reducing the likelihood of errors that could lead to contamination, rework, or compliance breaches. A well-trained workforce means fewer disruptions, increased safety, and improved project timelines.

Who Needs Water Hygiene Training?

The National Water Hygiene card is a mandatory requirement for anyone working on behalf of a UK water company in roles that involve contact with the water supply, including:

  • Water company employees
  • Subcontractors
  • Contractors handling clean water infrastructure
  • Self-Lay Organisations (SLOs)

Holding this certification ensures that individuals are competent and knowledgeable about best practices for working with drinking water networks.

What Does the Training Cover?

The National Water Hygiene training includes key topics such as:

  • The significance of water as a valuable resource
  • How waterborne diseases spread and how to prevent contamination
  • The risks and consequences of poor hygiene practices
  • Safe working procedures to maintain water quality

Upon successful completion of the course, participants receive a National Water Hygiene EUSR photo ID card, valid for three years.
