Cities Accelerate Repairs to Stop Water Leak Crisis

Brussels is investing billions to digitise Europe’s water networks, aiming to cut leaks and improve data quality even as cyber threats test the new systems.

Smart meters roll out in Poland

In Bytom, a mining town in southern Poland, engineers from Emitel have spent the past year fitting remote‑reading devices to more than 6,000 water meters. Further west, in Wrocław, the same firm is installing 70,000 additional meters in partnership with HSB Stella, a local distributor of Itron devices. The installations replace traditional analog meters with radio‑enabled units that transmit usage data in real time.

Local officials say the upgrade allows town halls to detect a burst pipe from a control‑centre dashboard rather than waiting for a resident’s emergency call. The technology mirrors the European Commission’s broader plan to modernise water infrastructure across the bloc.

EU policy and funding framework

On May 27 the Commission launched a call for evidence on an EU‑wide Action Plan for the Digitalisation of the Water Sector, inviting utilities, river‑basin managers and tech firms to respond by June 24. Commissioner Jessika Roswall said the plan would “unlock the potential of new technologies and digital solutions.” The Commission estimates that smart meters could cut water consumption by up to 25 percent, while digital monitoring could save an additional five to eight percent and automated leak detection another seven to 14 percent.

Funding is already moving ahead of the policy. Edouard Perard, head of the European Investment Bank’s water division, oversees a €15 billion lending programme scheduled for 2025‑2027, intended to attract another €25 billion of private capital. “This is where water meets business,” he told the outlet last year.

On Spain’s Costa del Sol, the local utility Acosol is implementing a €348 million investment plan approved after repeated droughts, with the EIB covering €175 million. In March, commission vice‑presidents Raffaele Fitto and Roxana Mînzatu signed a mid‑term reprogramming that redirected €3.1 billion of cohesion funds toward water resilience, part of a €34.6 billion shift across five strategic priorities. Cyprus, despite its small size, allocated €64 million of its own budget to water projects.

Cybersecurity risks emerge

Digitalisation also brings new vulnerabilities. In December, Romania’s National Cyber Security Directorate confirmed a ransomware attack on Apele Române, the state water agency. The breach affected around 1,000 IT systems and ten of the agency’s eleven river‑basin administrations. Attackers used Windows BitLocker to encrypt files and demanded contact within a week.

The agency reported that dam operations and flood‑defence systems continued to run, managed locally with phones and radios, but its website remained offline for days. The incident highlighted a gap: Romania’s water infrastructure had not yet been linked to the national cyber‑protection system designed for critical services. A smart meter, after all, is a networked device.

For the private sector, the gap between ambition and readiness creates business opportunities. Pieter Fossel, chief executive of Hydrosat, raised €51 million in January to expand a satellite‑based water‑monitoring service into Central Asia, the Middle East and Latin America. Water Europe, an industry body, is pushing Brussels to adopt a Digital Single Market for Water Data, enabling sensors, meters and monitoring platforms to communicate across borders rather than remain siloed in national systems.

In a region that stretches from the Western Balkans to the Caucasus, much of the pipework still dates back to the Soviet era. Interoperable standards and EU financing could matter more than the meters themselves, because they provide a framework for upgrading aging infrastructure.

Nearly a third of the water pumped into the EU’s public supply networks disappears before it reaches a tap, according to the European Environment Agency. Losses exceed 40 percent in Bulgaria, Croatia and Italy, while the Netherlands records losses of about five percent. The figures suggest there are still many leaks to plug.

Past modernization efforts often focused on replacing hardware without a coordinated digital strategy, limiting the potential for real‑time leak detection. The current approach ties financing to measurable efficiency gains, a shift that could accelerate the closing of water loss gaps.

While the EU’s funding and policy framework promises substantial improvements, the Romanian ransomware episode serves as a reminder that digital transformation must be paired with robust cybersecurity. Without such safeguards, the very tools intended to reduce waste could become points of failure.
