The crucial battle for water is playing out in Brussels

The crucial battle for water is playing out in Brussels
The European water crisis is no longer a concern limited to the arid regions of the Mediterranean. Even historically water-rich areas, such as the Flanders region, are experiencing increasing pressure on their groundwater reserves. At the same time, extreme weather events and related challenges are intensifying: prolonged droughts, flash floods, chemical contamination and higher energy costs for water treatment.

In this context, Brussels is redefining the rules of the game. From the new Urban Waste Water Directive to the revision of the Water Framework Directive, through to the crackdown on PFAS, in the coming months the EU will make decisions destined to directly influence the quality, safety and costs of water for 450 million citizens and 32 million businesses. What is at stake concerns not only environmental protection, but also industrial competitiveness, public health and the economic sustainability of water services. Sensitive issues are on the table: the “polluter pays” principle, the management of emerging contaminants, the balance between industrial transition and ecosystem protection, right through to new energy and digital challenges.

Urban wastewater: who pays for the pollution?
The first issue concerns urban wastewater and the revision of the directive, effective 1 January 2025 (UWWTD). The regulation updates historic legislation from 1991, introducing stricter standards against emerging pollution and adopting a “One Health” approach.

The most controversial point concerns the Extended Producer Responsibility (EPR) scheme, requiring the pharmaceutical and cosmetics industries to cover at least 80% of the additional costs of so-called “quaternary treatment” necessary to remove micropollutants from wastewater. In February 2026, the EU Court of Justice dismissed the appeals filed by the two industries, confirming the “polluter pays” principle enshrined in Article 191 of the EU Treaty. The Commission argues that the EPR scheme serves as a tool to shift environmental costs onto manufacturers while incentivising less impactful products. Member States will have to transpose the directive by 2027, and the EPR scheme will be fully operational by 2028.

The revision of the Water Framework Directive
The second file concerns the Water Framework Directive, adopted in 2000 and currently under review after 25 years. It is the EU’s fundamental legislation for the protection of rivers, lakes and groundwater, and serves as a global benchmark. It is, however, facing difficulties in integrating with national administrative systems, as well as mounting economic pressures. The debate centres on a delicate balance: updating the legislation without weakening environmental protection standards. The mining sector, in particular, is calling for greater flexibility in the rules protecting water and wetlands, as Chris Baker, director of Wetlands International Europe, explains. Energy transition requires lithium and minerals essential for batteries, turbines and digital technologies, but these are often found in protected areas. The challenge for Brussels will therefore be to reconcile strategic autonomy with the protection of ecosystems, preventing the race for raw materials from compromising the quality of water resources.

PFAS: the “forever chemicals” conundrum
The third area of concern is PFAS, per- and polyfluoroalkyl substances used in numerous industrial processes, dubbed “forever chemicals” due to their extreme persistence in the environment and the human body. A European Commission report, published in January 2026, estimates that without intervention, the cost of contamination will reach €440 billion by 2050. Intervening at source by 2040 would save around €110 billion, whereas simply treating contaminated water would cost over €1 trillion.

In recent years, the EU has already banned the most dangerous substances and, in October 2025, imposed restrictions on fire-fighting foams. The decisive step is still underway: on 26 March 2026, ECHA’s scientific committees voted in favour of a universal restriction on all PFAS, with selective exemptions. A final opinion paper is expected by the end of 2026. A 60-day public consultation, open to businesses, researchers and citizens, closed on 25 May. The phasing out of PFAS will require radical changes to industrial supply chains and could drive innovation towards a more circular and less toxic chemical industry.

From service providers to resource managers
Beyond individual policy areas, other challenges are set to reshape the water sector in the coming years. The new Waste Water Directive introduces energy neutrality targets and pushes for greater integration between the water sector, waste management, heat recovery and hydrogen production. Meanwhile, interest is growing in the recovery of nutrients from wastewater, a topic that could feature in the future Circular Economy Act. Article 8 of the Drinking Water Directive introduces an obligation to monitor risk at river basin level — a provision that is often underestimated but which could reshape the relationship between operators and local authorities. In addition to this are the digitalisation of infrastructure and climate resilience: floods and droughts call for predictive systems, mitigation plans and coordination between public administration and the productive sectors.

The result is a transition in which, some observers believe, water companies will become entities that manage the water cycle, recover energy, monitor groundwater quality and plan for the resilience of the territory. A shift from “service providers” to “resource managers”.
