Europe is facing a greater threat around water scarcity. In fact, this is already a reality affecting communities, infrastructure and economic activity across the continent. As extreme weather intensifies, droughts disrupt rainfall patterns and increases the frequency of extreme flooding, Europe is facing an urgent challenge to secure a robust and resilient water infrastructure.
With 40% of the world’s water supply projected to be in deficit by 2030*, the EU’s newly adopted Water Resilience Strategy arrives at a critical moment. Its ambition is clear: restore the water cycle, improve water efficiency by 10% by 2030, strengthen infrastructure against droughts and floods, and drive industrial water reuse. Yet policy alone will not deliver resilience at the speed or scale required. Real progress depends on partnership, technical expertise and practical delivery. Industry must be part of the solution.
Europe’s Water Stress Is Already Here
Water stress is no longer isolated or seasonal across Europe. Thirty percent of the population experiences water stress every year, while 12% live in areas prone to river flooding — floods that have caused more than €170 billion in damage since 1980. At the same time, groundwater, which supplies two thirds of the EU’s drinking water, is under increasing pressure from pollutants such as nitrates and pesticides.
Droughts are also becoming more frequent and severe, costing Europe up to €9 billion annually*. The European Commission estimates that €255 billion will be needed by 2030 simply to meet existing water legislation and improve efficiency. This is not just an environmental issue; it is an economic and social challenge that affects housing supply, industrial development, public health and Europe’s overall competitiveness.
Bridging the Water Gap
At CRH, we welcome the ambition of EU water legislation, including the Water Resilience Strategy and the Urban Wastewater Treatment Directive. These frameworks set important goals for pollution reduction, long-term resilience and circular water use. However, ambition must be matched with implementation that reflects engineering reality, operational constraints and market dynamics.
Operating across diverse European markets, CRH brings extensive experience in water infrastructure, stormwater management and resilient construction. From this perspective, we believe three policy barriers must be addressed to accelerate Europe’s water transition:
- Stronger enforcement of existing legislation, closing the gap between ambition and delivery.
- A dedicated central EU fund to support the deployment of essential water infrastructure.
- Harmonized EU wide standards and certifications for water, stormwater and wastewater infrastructure, replacing today’s fragmented national systems.
Without consistent standards and predictable investment, deploying resilient infrastructure at scale will remain slow, complex and costly.
The Case for EU Wide Standards
One of the greatest obstacles to delivering water resilience at scale is the fragmentation of standards across EU Member States. Differing national certification systems slow deployment, increase costs and hinder industrialization. This fragmentation weakens the EU single market and undermines competitiveness.
We believe the solution is clear: EU wide harmonization of standards for stormwater and wastewater management. Common standards would accelerate infrastructure rollout, encourage innovation and allow industry to deploy proven solutions more rapidly across borders.
Designing Cities That Work With Water, Not Against It
Europe’s cities were largely built for a different climate. Impermeable surfaces and aging drainage networks are struggling to cope with heavier rainfall and more intense storms. When these systems fail, flooding can quickly overwhelm homes, businesses and transport networks.
This is why we see growing momentum behind Sponge Cities — urban environments designed to absorb, retain and manage water naturally. Nature-based and engineered solutions such as permeable paving, rain gardens, swales and green roofs help regulate stormwater runoff while delivering wider benefits, including improved biodiversity, local cooling and better air quality.
Across Europe, we support communities through stormwater solutions that drain, filter, retain, infiltrate and transport water, helping protect people, critical infrastructure and the environment from flood risk. Our businesses Tarmac, Stradal, RC Products, Roadstone and Hydro International all have a range of stormwater solutions installed in the UK, France, Denmark and Ireland.
Addressing Water Scarcity Through Circularity
Flooding is only one side of Europe’s water challenge. Many regions are also facing increasing scarcity as population growth, new housing and water intensive industries compete for limited supply. This raises difficult questions about prioritization and long-term resilience.
Decentralized and circular water systems offer part of the answer. Capturing, treating and reusing water locally reduces pressure on freshwater sources, lowers costs, reduces emissions and strengthens resilience to changing weather and conditions.
Across our businesses, we are investing in technologies that support these outcomes, including advanced filtration, water reuse systems and network efficiency solutions. Through investments in VODA.ai, which helps utilities assess pipe condition and prioritize repairs, and FIDO AI, a leader in leak detection technology, we are supporting smarter, more efficient water and wastewater infrastructure aligned with EU digitalization goals.
Reducing leakage is particularly critical. Across Europe, significant volumes of treated drinking water are lost every day through aging pipes. Tackling these losses is one of the most cost-effective ways to improve water efficiency and strengthen system resilience.
Protecting Critical Water Infrastructure
As weather-related risks grow, so too does the need to protect water systems from pollution, power outages, cyber threats and geopolitical disruption. Investing in robust treatment solutions — especially those that require minimal energy to operate — is essential to safeguarding public health and ensuring continuity of supply.
Ensuring the resilience of water infrastructure is not optional. It sits at the very core of adaptation, economic stability and public trust.
No Time to Waste
Europe’s water challenges are intensifying, but the path forward is clear. The EU has set strong policy direction; what is now required is faster implementation, aligned standards and meaningful collaboration between policymakers and industry.
At CRH, we are committed to being a proactive partner in building a water secure future. Our solutions support water capture, treatment, distribution, wastewater management and flood defence across the regions where we operate, and we will continue to invest in innovation to accelerate the deployment of resilient infrastructure
Water is Europe’s most precious resource. There is no time to waste. The decisions made today will determine whether future generations will face a society braced for further disruption and scarcity — or benefit from a foundation ready for whatever comes next.
