Reduce complexity

An all-new shared reference point for efficient conformity assessment in the drinking water materials sector.

Fit4DW is a secure digital infrastructure that connects suppliers, manufacturers, laboratories and certification bodies around verified material and compliance information. It helps the sector move from fragmented exchanges to a single trusted reference point, reducing repetitive work, administrative friction, and uncertainty, while protecting sensitive supplier know-how.

See how Fit4DW works.

Conformity assessment in the drinking water materials sector involves many stakeholders, strict requirements and sensitive information. This video shows how Fit4DW helps bring structure to that process by creating one secure environment for verified information, controlled access and more efficient collaboration across the chain.

From chasing information to working from one trusted reference point.

Fit4DW is more than a database. It functions as a digital nerve centre for the drinking water materials sector: a central platform where relevant material and compliance information can be organised, verified, reused and accessed in a controlled way. For manufacturers, the real challenge under the Drinking Water Directive is not only regulatory. It is operational. Critical information is often scattered across suppliers, laboratories, certification bodies and internal teams. That creates repeated requests, unclear verification status, delayed decisions and unpredictable timelines. Fit4DW helps solve this by creating one structured environment for verified information. This gives stakeholders more overview, supports better early decision-making and helps reduce friction across the conformity assessment process.

Our services

What Fit4DW does
Fit4DW connects key information flows across the drinking water materials chain.

The platform helps to:

organise verified material and compliance information;
reduce fragmented one-to-one exchanges;
support reuse of relevant documentation and test information;
protect supplier IP through controlled access;
provide clearer insight into available certificates, reports and verification status;
support more predictable conformity assessment processes.

What this delivers
Fit4DW helps stakeholders work from a shared reference point instead of separate files, repeated requests and disconnected communication.

This supports:

earlier access to verified information;
less back-and-forth between manufacturers, suppliers and assessment parties;
fewer unnecessary repeated reviews or testing cycles;
stronger protection of formulations and sensitive know-how;
lower administrative workload;
better-informed material and supplier choices;
more predictable development and certification timelines

Who works with Fit4DW?

Manufacturers
Fit4DW helps manufacturers access verified information earlier, reduce administrative backand-forth, and move through conformity assessment with more predictability and control. It also supports better-informed choices earlier in the process.

Suppliers
Fit4DW helps suppliers protect formulations and other sensitive know-how while reducing the burden of repeated information-sharing requests. It enables compliance support without unnecessary exposure of IP.

NoBos / Labs / Certification Bodies
Fit4DW helps NoBos and labs work with better organised information, more reuse, and less unnecessary repetition. This supports more efficient compliance reviews and better use of expert time.

The Industry
Fit4DW helps the industry move from fragmented exchanges to a more connected and workable system. It creates a shared operational foundation for better collaboration, more transparency, and greater readiness for the DWD.

Frequently asked questions

Is Fit4DW only a database?

No. Fit4DW includes database functionality, but it is more than a static database.

Fit4DW is a secure digital infrastructure and shared reference point for verified drinking water materials information. It helps suppliers, manufacturers, laboratories and certification bodies organise, access and reuse relevant material, test, certificate and approval information in a controlled way.

The goal is to reduce fragmented exchanges, repeated requests and unnecessary administrative work across the conformity assessment process.

Who is Fit4DW for?

Fit4DW is designed for stakeholders across the drinking water materials chain, including:

raw material suppliers;
intermediate product manufacturers;
final product manufacturers;
applicators;
laboratories;
certification bodies;
Notified Bodies.

For manufacturers, Fit4DW supports earlier access to verified information and better decision-making during product development. For suppliers, it helps reduce repeated disclosure requests while protecting sensitive know-how. For laboratories and certification bodies, it supports more structured information flows and more efficient review processes.

Will Notified Bodies and test laboratories work with Fit4DW?

Fit4DW is designed to support cooperation between manufacturers, suppliers, laboratories, certification bodies and Notified Bodies.
The current Fit4DW website states that discussions have taken place with members of the “Future notified bodies group” and that participants are supportive of the database.
The value of Fit4DW increases as more stakeholders use the platform, because verified information becomes easier to find, access and reuse. This supports a more efficient conformity assessment process for the entire chain.
