European Drinking Water Directive (EU) 2020/2184 – Complete Guide for Water System Manufacturers and Importers
[2025-11-16] | By Xiamen Smart Water Technology Co., Ltd. Allen Huang
The European Drinking Water Directive (DWD) is one of the most important regulations for any company producing or importing water-contact materials into the EU-especially kitchen taps, under-sink filtration systems, instant boiling water taps, and 5 in 1 water tap systems.
This guide explains the latest requirements, compliance timelines, and what global brands must prepare for, especially those working with ODM suppliers like Xiamen Smart Water Technology Co., Ltd.

The European Drinking Water Directive, updated in December 2020, is the EU's unified regulation governing all materials and products that come into contact with drinking water. It replaces the older 1998 version and aims to:
- Ensure safer drinking water for consumers
- Standardize material testing across all EU member states
- Reduce harmful chemical migration
- Control new pollutants such as PFAS and microplastics
From kitchen taps to filtration systems and heating tanks, any product touching water intended for human consumption must meet this standard.
Before 2020, manufacturers entering the EU market needed multiple national certificates (WRAS, ACS, KIWA, DVGW, UBA, etc.). This increased cost, testing time, and complexity.
Old system:
Multiple certificates for different EU countries.
New EU DWD:
One certification → Access to all EU member states.
This significantly reduces compliance cost-especially beneficial for brands building international product lines such as 5 in 1 water tap systems.
The Directive applies to all materials and components that contact drinking water in:
- Homes
- Restaurants
- Food manufacturing
- Commercial buildings
- Public water systems
Includes:
- Water taps (including boiling, chilled, sparkling & 5-in-1 taps)
- Under-sink water dispensers
- Filters & cartridges
- Water tanks
- Valves, pumps, pipes, fittings
- Water heaters & boiling-water tanks
- Seals, rubbers, plastics & metallic parts
If water flows through it or touches it-it must comply.
(1). Positive List System
Each material must use substances approved on the EU's positive list, including:
- Organic materials
- Metals
- Cementitious materials
- Ceramics & enamels
(2). Minimum Hygiene Requirements
Manufacturers must prove:
- No harmful substance migration
- No microbial growth
- No change in taste, smell, color of water
(3). Emerging Contaminants Control
The new Directive addresses previously unregulated pollutants:
| Substance | Limit |
|---|---|
| PFAS (Total) | 0.5 μg/L |
| PFAS (Individual) | 0.1 μg/L |
| Microplastics | Mandatory monitoring |
(4). Mandatory Certification Marking
From 2033 onward, all compliant products must carry a unified DWD mark, with strict rules for location, size, and visibility.
EU requires all materials to be tested according to their category:
- Metals
- Plastics & polymers
- Rubbers & elastomers
- Ceramic & enamel surfaces
- Cement-based materials
Testing includes:
- Formulation review
- Migration testing (taste, odor, color, substance release)
- Microbial resistance
- Restricted substance analysis
- PFAS and microplastic assessment (new requirement)
For the first time, PFAS and microplastics are officially regulated.
Why this matters for faucet brands:
- Many traditional brass alloys release PFAS or heavy metals
- Older plastic formulations may fail microplastic migration tests
- Water heating systems (like boiling-water tanks) must show zero harmful release at high temperatures
Brands selling 5-in-1 or multi-functional water taps must ensure water tasting quality and safety remain consistent even under hot or sparkling water conditions.
According to Delegated Regulation (EU) 2024/371:
- All certified products must display the DWD compliance mark
- Mark must be on a visible part of the product
- Digital documentation and traceability are required
This ensures transparency for both installers and consumers.
| Year | Requirement |
|---|---|
| 2020 Dec | DWD approved |
| 2021 Jan | Directive legally in force |
| 2023 Jan 12 | Member states must convert DWD into national laws |
| 2024 Jan 12 | ECHA releases first positive list of allowed chemicals |
| 2024 Jan 23 | EU releases implementation decisions & hygiene standards |
| 2026 Dec 31 | Applies to all new installations/renovations |
| 2027 Jan 1 | Old national certification routes close |
| 2032 Dec 31 | All drinking-water-contact products must hold DWD certification |
| 2033 onward | Only DWD-certified products allowed in the EU |
1. Unified Certification Lowers Cost
One test → All EU markets.
2. Materials Must Be Upgraded
Old brass grades like CW617N, CW511L, CW757S are no longer allowed because of high lead release.
3. Factories Must Upgrade Production
Manufacturers must:
- Adopt low-lead or lead-free copper alloys
- Use safer polymers
- Improve surface treatment to reduce migration
4. ODM Partners Must Be Ready
EU buyers now expect DWD-compliant product lines from manufacturers.
The new positive list excludes many traditional copper alloys widely used in taps.
Lead extraction limit:
≤ 5.0 μg/L
This requires:
- New alloy adoption
- Redesigning components
- Additional testing for heating tanks and 5-in-1 water tap systems exposed to high water temperatures
Before 2027
- Secure national certificates (ACS, AOC, KIWA, UBA, etc.) for existing materials
- Begin switching to new copper alloys
Before 2032
- Complete full DWD certification
From 2033
- Only ship DWD-certified drinking water products into the EU
| Requirement | Details | Applies To |
|---|---|---|
| Lead Release | ≤ 5.0 μg/L | Metals, brass alloys |
| PFAS (Total) | ≤ 0.5 μg/L | All water-contact materials |
| Microplastics | Mandatory monitoring | Plastics, seals |
| Taste/Odor | No noticeable change | All materials |
| Material Approval | Must use EU positive list | Metals, plastics, rubber |
| Certification Mark | Mandatory from 2033 | Finished products |
| Migration Testing | Organic/inorganic substances | All water-contact surfaces |
| Microbial Growth | No microbial growth allowed | All components |

1. Do all taps entering the EU need DWD certification?
Yes. After 2032, DWD certification becomes mandatory for all water-contact products.
2. Are traditional brass alloys still allowed?
Most older alloys like CW617N are not on the new positive list due to lead release limits.
3. Does the DWD apply to hot-water or multi-function taps?
Yes. Boiling, chilled, sparkling, filtered, and 5-in-1 water tap systems must all comply.
4. Can existing national certificates still be used?
Yes, but only until they expire and not after 2032 Dec 31.
5. How long does DWD certification take?
Typically 6–12 months depending on material category and testing volume.
