UBA Conformity Attestation: Hygiene Requirements for Products and Materials in Contact With Drinking Water

Do you need to show compliance with the German UBA requirements for your drinking water contact products or materials? Learn more about this approval and how we can assist you.

We provide comprehensive testing and certification services to help manufacturers show compliance with the German Umweltbundesamt (UBA) requirements for the hygiene of products and materials in contact with drinking water.

What is this approval?

This conformity attestation approval is performed against the requirements outlined in TrinkwV, the Drinking Water Ordinance issued by by the German Umweltbundesamt (Federal Environment Agency). This is a legally binding set of requirements which ensure that these substances do not pose a risk to human health or the environment when in contact with drinking water.

Key Definitions

  • UBA: Umweltbundesamt (German Environment Agency)
  • Drinking Water Ordinance (TrinkwV): Set by UBA, these are the legal requirements for all drinking water contact products used in Germany.
  • KTW-BWGL: Name of the requirements specifically for plastics and organic materials in contact with drinking water

Is this certification required?

Compliance with UBA drinking water requirements applies to various materials and products that encounter drinking water, including pipes, fittings, coatings, and more.

Compliance is mandatory for products sold in Germany and may also be required in other European countries to ensure compliance with EU regulations. A certificate issued by an accredited body is sufficient to show compliance. See our page on the EU Drinking Water Directive for more information on how this will change in the future.

Why is this certification important?

Certification allows manufacturers of all types of products and materials throughout the water system supply chain to show their products meet these requirements without question.
