About the initiative

A shared effort to reduce complexity in drinking water materials compliance.

Fit4DW was created to help the drinking water materials sector move from fragmented information exchange to a more structured, secure and efficient way of working. The initiative supports stakeholders across the chain by creating a shared reference point for verified material and compliance information. This is why Fit4DW was created.

The challenge is fragmentation, not just regulation. Clean drinking water is essential. So are health, safety and trust. That is why products and materials used in contact with drinking water must comply with strict requirements. The European Drinking Water Directive sets a clear direction for high standards and harmonisation. But in practice, the challenge for many organisations is operational. Information is often scattered across suppliers, manufacturers, laboratories and certification bodies.

Different parties use different formats, different terminology, different levels of detail and different communication routes. Sensitive supplier information is often handled through separate NDA processes. Manufacturers may discover risks too late in development. Laboratories and certification bodies may receive incomplete or fragmented dossiers. This creates a bureaucratic labyrinth: more handovers, more repeated requests, more uncertainty and more pressure on timelines. Fit4DW was created to help the sector work differently.

What the sector needs to overcome:
Across the drinking water materials chain, stakeholders face recurring challenges:

  • manufacturers need earlier access to verified information;
  • suppliers need to protect formulations and confidential know-how;
  • laboratories and certification bodies need better organised documentation;
  • repeated requests create administrative workload;•duplicated testing and repeated reviews can increase costs and delays;
  • unclear verification status makes planning difficult;changes in materials, suppliers or regulation can create lifecycle risk;
  • fragmented communication makes the process harder to control.The result is a process where organisations spend too much time chasing information instead of working from a trusted reference point.


Fit4DW has the role of shared reference point for the sector and provides a secure digital infrastructure where relevant material and compliance information can be organised, verified, reused and accessed in a controlled way.

It does not replace the roles of suppliers, manufacturers, laboratories or certification bodies. Instead, it helps connect them through a more structured information environment.

That is why Fit4DW is positioned as a central platform and shared reference point for the sector. It supports a shift from fragmented exchanges to a more connected and predictable way of working.

The ambition is simple: From chasing information to working from one trusted reference point.
