- Organizations involved in the construction and management of drinking water installations, such as municipalities and housing associations.
With a Kiwa Watermark certificate, manufacturers can demonstrate that their products are suitable for use in the Dutch drinking water sector and comply with the applicable requirements and guidelines.
Why Kiwa Watermark?
Kiwa Watermark certified plastic piping systems comply with the relevant Dutch and international standards for products used in drinking water distribution. In addition, the products are assessed against the strict hygienic requirements established by the Dutch government for materials and products that come into contact with drinking water. During the certification process, various aspects are evaluated, including:
- The quality and composition of the materials used
- Mechanical properties, such as pressure resistance, tensile strength and resistance to mechanical loads
- The durability and expected service life of the piping system
- The performance of joints and fittings
- Hygienic properties and their potential impact on drinking water quality
- Control of the production process and consistent product quality
Only products that meet all applicable requirements and demonstrate consistent product quality are eligible for certification under the Kiwa Watermark certification scheme. Through periodic inspections and audits, Kiwa verifies that certified products continue to comply with these requirements.
