The EU Drinking Water Directive (DWD)-officially Directive (EU) 2020/2184-is the European Union's updated legal framework designed to improve the safety and quality of drinking water for all EU residents.
Its purpose is simple:
- Protect human health from contaminated drinking water
- Improve access to clean and safe drinking water
- Set unified safety requirements for all materials and products that come into contact with drinking water
This includes everything from water pipes and valves to advanced hot water tap systems, boiling water taps, and under-sink filtration products.
DWD applies to any material, part, or product that touches drinking water, including items used for:
- Drinking
- Cooking
- Food preparation
- Household use
- Food manufacturing or processing
The directive covers products used in residential, commercial, and public facilities.
If a product touches water used for human consumption-it must comply with DWD.
This includes:
- Water pipes & fittings
- Pumps
- Valves
- Meters
- Drinking faucets
- Boiling & hot water taps
- Water heating systems
- Under-sink dispensers
- Filtration systems
For global brands selling to the EU, this regulation is mandatory, not optional.
| Year / Deadline | Requirement |
|---|---|
| Dec 2020 | EU approves revised Drinking Water Directive (EU 2020/2184) |
| Jan 2021 | Directive enters into force |
| Jan 12, 2023 | All EU member states must adopt DWD into national law |
| Jan 12, 2024 | ECHA releases first "Positive List" of approved chemical substances |
| Jan 23, 2024 | EU publishes detailed implementing rules and minimum hygiene standards |
| Dec 31, 2026 | All new installations or renovations must use DWD-compliant materials |
| Jan 1, 2027 – Dec 31, 2032 | Transition period; existing national certificates (ACS, KTW-BWGL, etc.) still valid |
| Jan 1, 2033 | Full enforcement - all products on the EU market must hold DWD certification |
This long transition period gives manufacturers time to adapt, but the requirements are clear:
➡️ By 2033, every drinking-water-contact product must be DWD-certified to enter the EU market.
The new DWD rules apply to all water-contact materials, including:
- Metal components
- Plastics
- Rubber & elastomers
- Coatings
- Sealants
- Solders
- Mechanical parts in direct water contact
- Heating chambers for boiling water taps
- Under-sink hot water tanks
- Filter housings & cartridges
Whether the product heats, stores, distributes, or dispenses water-it falls under the directive.
Article 11 of EU 2020/2184 outlines the minimum hygiene and safety requirements.
Testing Categories Include:
- Formulation Review (full material transparency and safety assessment)
- Microbiological Tests
- Migration Tests, including:
Taste
Odor
Color
Release of substances into water
- Restricted Substances Testing
- Future Planned Testing:
Microplastics monitoring
PFAS detection (per- and polyfluoroalkyl substances)
DWD introduces one of the strictest drinking water safety frameworks globally, directly impacting manufacturers of hot water tap systems and boiling water taps.
According to the EU Delegated Regulation (EU) 2024/371:
- Products must display the DWD certification marking
- Marking size and placement are strictly defined
- Mark must be visible, legible, and permanent
Failure to apply the marking = non-compliance, even if testing is passed.
If you manufacture or distribute drinking-water-contact products for the EU market, you must:
- Confirm all materials against the ECHA Positive List
- Perform full DWD testing for each material & final product
- Obtain DWD certification from an accredited body
- Update product labeling with the official DWD mark
- Prepare documentation for EU market surveillance checks
Without proper DWD certification:
➡️ Products will be considered illegal in the EU starting Jan 1, 2027 for new installations, and Jan 1, 2033 for all sales.
| Component | DWD Compliance Requirements | Notes |
|---|---|---|
| Heating Tank | Migration, chemical safety, formulation review | Essential for hot water tap systems |
| Boiling Water Tap Body | Metal leaching tests, odor/taste tests | Applies to stainless steel, brass, plated finishes |
| Water Path Tubing | Microplastics, PFAS, chemical testing | Must match ECHA Positive List |
| Filter Cartridge | Extractables, formulation disclosure | A major focus area in 2024–2030 |
| Internal Valves | Mechanical + chemical safety | Must meet updated hygiene standards |
| Seals & O-rings | Material formulation + restricted substances | Rubber materials face stricter testing |

Q1: Is DWD certification mandatory?
Yes. It is a legal requirement in the EU and applies to all drinking-water-contact products.
Q2: Does DWD replace other certifications like WRAS or KTW?
From 2033, the EU Drinking Water Directive (DWD), supported by Minimum Hygiene Requirements (MHR), will apply across all EU Member States.
Existing national schemes (such as KTW in Germany or ACS in France) are being harmonised under this framework.
As the UK is no longer part of the EU, national requirements, such as WRAS approval, remain applicable to products entering the UK market.
Q3: Do boiling water taps need DWD certification?
Absolutely. Any component of a boiling water tap that touches drinking water must pass DWD testing.
Q4: Are plastic components tested differently?
Yes. Plastics undergo additional migration and microplastic assessments.
Q5: What happens if a product doesn't comply by 2033?
It cannot be legally sold, installed, or distributed in the EU.
