The short answer. The EU Water Framework Directive (WFD, in Dutch the Kaderrichtlijn Water or KRW) requires good status for surface water and groundwater, and 20 December 2027 is the final deadline. The Netherlands currently meets about 83% of its KRW targets, and the government has said it will not meet all of them by that date. For industrial sites, this does not change the rules overnight, but it tightens how much room your receiving water has left. Every permit application, and every request for custom rules (maatwerk), for a discharge to surface water is tested against that room through the immission test, and where a water body already fails for a substance, adding more of it becomes very hard to permit.
What the Water Framework Directive requires
The WFD sets quality standards for chemical substances and metals, and ecological objectives for plants, fish and other aquatic life, for every water body. Member states report every six years through river basin management plans. The Netherlands has four main river basins: the Rhine, Meuse, Scheldt and Ems.
The original deadline was 2015, with the possibility of two six-year extensions. Many countries, the Netherlands included, used them, which is why 2027 is now the end point.
Where the Netherlands stands on the KRW 2027 targets
The Netherlands has around 750 surface water bodies and roughly 100,000 individual KRW targets. Status is judged “one out, all out”: if a single standard fails, the whole water body fails. By that measure, no Dutch water body meets every standard.
In a 2026 letter to the Tweede Kamer, the minister of Infrastructure and Water Management stated that even with extra effort, the Netherlands will not fully meet its obligations by 20 December 2027. The share of targets met, currently about 83%, is expected to rise but not reach 100%. The government intends to rely on the exemptions the directive allows. In 2024, about 75% of the targets were met.
What happens after the 2027 WFD deadline
After 2027 the directive offers limited flexibility. Deadlines can only be extended where natural conditions mean a water body needs more time to recover after measures have been taken (Article 4(4)). Alternatively, a less stringent objective can be set where reaching good status is technically infeasible or disproportionately expensive, subject to strict conditions (Article 4(5)).
Neither route is a free pass. Both require justification per water body, and if the European Commission considers a member state’s implementation inadequate, the matter can end in a European Court ruling and a fine.
What it means for industrial dischargers
The link between the KRW and your permit is the immission test. When you apply for a new or changed discharge to surface water, you must show that it fits within the space between the receiving water’s current quality and its standard, assessed at the edge of a mixing zone. The test applies to all surface waters, not only designated KRW water bodies, and it covers nutrients and salinity as well as chemical substances. Its purpose is to make sure discharges do not cause deterioration in the sense of the KRW.
In practice, your position depends on the status of the receiving water for each substance you discharge. The table below is our practical reading of how that plays out. Your competent authority makes the actual decision.
| Receiving water status for a substance you discharge | What it usually means for your permit |
|---|---|
| Meets the standard with plenty of headroom | A well-designed discharge using best available techniques can normally be permitted |
| Meets the standard but close to the limit | Little immission space remains; an increase or expansion may require more treatment or a lower concentration |
| Already fails the standard | No room to add more; expect to need source reduction, additional treatment or a different discharge route |
| Substance of very high concern (ZZS) | Zero discharge is the starting point; an unavoidable residual needs to pass the immission test and is reassessed every five years |
This is why 2027 matters most for sites that want to grow. A stable, already permitted discharge is assessed against its existing permit. A production increase, a new process stream or a change of chemicals triggers a fresh assessment against a receiving water that may now have less room than when your permit was first issued.
Five questions to ask before your next permit change
- What is the current status of your receiving water body, and which parameters fail? Your water authority can tell you.
- Which of your substances, including salts and nutrients, overlap with the failing parameters?
- How close is your current discharge to the immission space for each of them?
- Can source reduction or stream segregation lower those loads before any treatment is considered?
- If not, which option changes the outcome: additional treatment, a different discharge route, water reuse, or minimum or zero liquid discharge?
For saline streams, remember that concentrating a brine reduces its volume but not the salt load it carries to the river. Our guide to industrial discharge permits in the Netherlands explains why, with a worked example.
How Brine Consulting can help
We help industrial sites prepare for a permit change or expansion by closing the water and salt balances, characterizing each stream, and comparing source reduction, treatment, reuse, MLD and ZLD on their effect on the immission result and on cost. We sell no treatment equipment, so our advice is not tied to any supplier.

Frequently asked questions
What is the deadline of the Water Framework Directive?
20 December 2027 is the final deadline for good status, after extensions from the original 2015 date.
Will the Netherlands meet the KRW targets in 2027?
Not fully. The government expects to meet more than the current 83% of targets but not all of them, and intends to rely on the directive’s exemptions.
Does the KRW apply directly to my company?
The directive binds member states, not companies. It reaches your site through the Omgevingswet and its decrees, through river basin management plans and, most directly, through the immission test applied to your discharge permit.
Will my existing permit be withdrawn after 2027?
Not automatically. The main effect is on new and changed discharges, which are assessed against the receiving water’s current quality. Authorities can also review permits, so stay informed about the status of your receiving water.
What is “one out, all out”?
A water body only achieves good status if every relevant standard is met. One failing parameter means the whole water body fails.
