The Barcelona Provincial Council successfully located and fixed 700 leaks in municipal water supply networks through an extensive inspection and repair campaign. This effort recovers a staggering three billion litres of water annually. Running between 2024 and 2025, the initiative launched during Catalonia’s most severe drought on record, highlighting the critical need to conserve every drop.

Engineers and technicians reviewed approximately 2,000 kilometres of pipes across 102 municipalities in the province. As detailed in a report first covered by La Vanguardia, the programme’s results demonstrate a significant step forward in reinforcing the region’s water security. The recovered volume is equivalent to the entire annual water consumption of the Berguedà comarca, or cities like Igualada and Vilafranca del Penedès, both home to over 40,000 residents.
A Sound Investment in Water Security
The Provincial Council of Barcelona, an institution supporting local governments, invested just under half a million euros into the detection programme. This investment yields substantial financial returns for municipalities; the conserved water translates to estimated annual savings of over €3 million. The initiative, therefore, underscores the Council’s crucial role in providing technical and financial resources to smaller towns often struggling to maintain ageing infrastructure.
Some leaks had been losing precious water for many years, a situation that became untenable during the recent historic drought. Consequently, the campaign has yielded dramatic results in several municipalities. For example, Rubió in the Anoia comarca reduced its daily water loss by 71%. Nearby, Calaf and El Bruc recorded savings of 27% and 37% respectively. In the Maresme region, Sant Andreu de Llavaneres cut its losses by 23%, saving enough water for 2,700 people daily. Similarly, Arenys de Munt achieved a 37% saving, equivalent to the daily needs of over 3,500 residents.
A Proactive Strategy for a Drier Future
Although the immediate crisis has eased, with reservoirs in Catalonia’s internal basins now close to full capacity for the first time in a decade, authorities are determined not to become complacent. Both the Provincial Council and local town halls view this campaign as the beginning of a sustained effort to modernise water infrastructure and build resilience against future shortages, an ongoing threat due to climate change.
This leak-detection programme is part of a much broader strategy. It complements a sectoral improvement plan for supply networks, backed by a €100 million budget for the 2024-2027 period. This forward-looking focus on upgrading critical systems reflects a wider trend of infrastructure investment across the region. For instance, recent projects include a €15.5 million overhaul of the Endesa power plant in Sant Adrià, a €9 million plan to restore city bridges and parks, and the steady progress of the L9 metro line extension.
By tackling the persistent problem of network losses, the Provincial Council is not just plugging holes; it is also laying the groundwork for a more efficient and sustainable water management system, better prepared for inevitable climate challenges.
