Who is this for?

Drinking water companies, water treatment companies.

When is this needed?

The Kiwa Water Mark is needed when you, as a producer or supplier, want to profile yourself on the market with products that meet all requirements: all functional requirements as well as all legal hygienic requirements specified in the “Materials and chemicals in the supply of drinking water and warm tap water Regulation” of the Dutch government.

What to do next

Steps to obtain a certificate with the Kiwa Water Mark are:

Fill in an application form and send it to Kiwa.

Kiwa sends a quotation, which is at the same time a concept-agreement, drawn up according to the handling of the Harmonized Standards;

After mutual signing of the quotation, the agreement is definitive and the initial application can start;

After positive results of the initial audit, the certificate will be issued;

The certificate is valid indefinitely;

A part of the agreement is an two annual audits.

Important aspects of the initial audit (steps 3 and 4) include:

a) Testing with regard to the product and/or performance requirements. Testing, often carried out in our own laboratories, demonstrates that the product meets the certification requirements for functional aspects, such as durability, dimensions, composition of materials, etc.;

b) Assessment of the production process, quality system and internal quality control (IQC) scheme. To ascertain that the producer is continually able to manufacture products that meet the certification requirements.

The periodic audits aim at the maintenance of the management system, in order to maintain confidence that the producer is still able to manufacture products that meet the certification requirements. The periodic audits include functional tests of the certified products.

The audit frequency is set at 1 time per year.

Conditions for the certification process are stated in the Kiwa Regulations for Certification and the General Terms and Conditions of Kiwa for the performance of orders.
