Water is our most precious resource, consistently undervalued despite sustaining ecosystems, fuelling economies, and underpinning human health. We often take its availability for granted. Consider the billions of litres consumed annually by thermal power plants for cooling, the critical role of water in hydrogen production, and the staggering 620 million litres of freshwater used yearly by an average data centre operated by major tech firms. Car manufacturers and chemical industries also heavily rely on this vital resource. Despite this profound dependence, water is frequently overlooked in policy, infrastructure, and public awareness, posing a significant threat to Europe’s environment, industries, and digital ambitions. To secure a resilient water future, a concerted pan-European effort, harnessing collaboration, innovation, and capacity building, is essential to safeguard this invaluable resource.
The water sector stands at a critical juncture, facing mounting pressures from climate change, population growth, and escalating pollution that are stretching our water systems to their limits. Across the European Union, the contamination of fresh and marine waters, including persistent per- and polyfluoroalkyl substances (PFAS)—"forever chemicals" linked to severe health issues—demands a comprehensive clean-up initiative. These water quality challenges are exacerbated by water quantity issues. Since 2021, parts of the Mediterranean region, including Spain, Italy, and Greece, have experienced prolonged droughts, severely impacting agriculture and urban water supplies. In 2024, devastating heavy rains and flash floods struck multiple EU states, resulting in tragic losses and billions in damages. These recurring water-related disasters incur billions of euros annually, underscoring the urgent necessity for resilient water management strategies.
To secure a resilient water future, a multi-faceted approach focusing on capacity building, innovation and strategic governance is essential
The European Union’s Water Resilience Strategy, endorsed by the European Parliament in May 2025, directly addresses these pressing challenges of water scarcity, flooding, and pollution. This strategy establishes ambitious objectives for water security, reuse, and the integration of circular economy principles. However, achieving these goals requires more than just policy frameworks. The revised EU Urban Wastewater Treatment Directive, effective since January 1, 2025, serves as a crucial cornerstone in this endeavour. It strengthens wastewater treatment by targeting a broader range of pollutants, including pharmaceuticals and PFAS, extending its reach to smaller agglomerations (1,000 population equivalents or more) by 2035, and introducing stricter standards for managing rainwater runoff and removing micropollutants. By reinforcing the polluter-pays principle, the directive ensures that industries and polluters are held accountable for the environmental damage they cause, thereby promoting cleaner water systems. These measures are vital for safeguarding water quality and supporting Europe’s wider environmental and economic aspirations.
Significant financial resources will be essential to implement novel treatment technologies and enhance monitoring capabilities as mandated by the new directive. Furthermore, achieving energy neutrality in water management will necessitate substantial upfront investments, even though long-term operational cost savings from reduced energy consumption are anticipated. Recognising these considerable funding demands, the novel Extended Producer Responsibility (EPR) scheme emerges as a pivotal mechanism for securing the necessary financial support specifically for the removal of micropollutants, thereby acting as a potential catalyst for the directive's successful implementation.
Engaging policymakers is crucial to facilitate the adoption of innovations, thereby enhancing Europe’s global competitiveness within the water sector. We must present compelling evidence of the economic and environmental advantages of these technologies, utilising data from trials to demonstrate cost savings and sustainability improvements. Regular dialogue through policy forums, such as those hosted by the European Commission and Water Europe, can ensure that innovations align effectively with regulatory frameworks. Streamlining approval processes and offering incentives, such as subsidies for utilities adopting advanced PFAS filters, can significantly accelerate their uptake. By clearly showcasing how these innovations strengthen the water sector and support interconnected industries across the water-energy-food nexus, we can position Europe as a global leader, driving both economic growth and environmental sustainability.

Sustaining the impact of innovation requires robust capacity-building initiatives. By equipping professionals with the necessary skills in emerging technologies, circular economy practices, and adaptive governance, we are cultivating a workforce that is well-prepared to address complex water-related challenges. Targeted training programs will empower professionals to manage water as the finite and precious resource it truly is. These efforts foster a knowledge-driven water community that fully recognises water’s intrinsic economic and social value, ensuring that sustainability is deeply embedded in decision-making processes across diverse sectors, from energy production to digital infrastructure development.
I am optimistic about the transformative potential of the new EIT Knowledge and Innovation Community on Water, Marine, and Maritime Sectors (EIT Water) to fundamentally reshape our approach to water security. By fostering synergistic collaboration across these interconnected sectors, EIT Water establishes a dynamic platform for crucial knowledge transfer and the sharing of innovative technologies, effectively addressing shared challenges such as sustainability, resource efficiency, and climate resilience. For instance, the integration of the water sector’s advanced analytical capabilities, such as sophisticated digital water management tools, with the maritime sector’s established expertise in IoT-driven logistics and efficient port operations can lead to groundbreaking innovations like real-time water quality monitoring systems for ports or sustainable ballast water treatment solutions. Simultaneously, the marine sector’s advancements in eco-friendly materials and cutting-edge sensor technologies can significantly bolster the resilience of water infrastructure, while maritime’s extensive global trade networks can facilitate the worldwide scaling of water-efficient solutions. Through EIT Water’s comprehensive pan-European framework, collaborative cross-sector education, joint research initiatives, and dedicated startup acceleration programs will drive a unified and thriving blue economy, delivering impactful innovations that effectively bridge freshwater systems, vital marine ecosystems, and critical maritime operations for a truly sustainable and resilient future.
In summary, while the path towards achieving comprehensive water security is loaded with significant challenges, there is considerable hope in our collective determination to address them. The persistent undervaluation of water poses a serious threat to Europe’s vital ecosystems, key industries, and ambitious digital agenda. However, the progressive EU Water Resilience Strategy, the strengthened revised Urban Wastewater Treatment Directive, and forward-thinking initiatives like EIT Water provide a robust and promising framework for meaningful progress. These concerted efforts demonstrate that strategic innovation, effective collaboration, and targeted capacity building have the power to fundamentally transform how we manage our precious water resources. By truly valuing water as our most critical resource and working collaboratively, we can collectively build a resilient and sustainable future where clean water effectively powers Europe’s ambitions, diligently protects our planet, and reliably ensures prosperity for generations to come.
