Water is going up in price in Barcelona and 22 other cities. The increase will be 2.9% from January 2026. Find out how it will affect your bill and which part of the charge will become more expensive. Why is it rising and which components have an influence? All the details in our analysis.
The price of water will rise again in Barcelona and 22 metropolitan municipalities from January 2026. After two years of steep increases, this time the rise will be 2.9%, amounting to about 80 cents more per two-month bill. This measure affects all consumption bands equally and marks the third consecutive year of increases after a decade of frozen tariffs.
Unlike in previous years, the Área Metropolitana de Barcelona (AMB) has decided to apply the same percentage increase to all users, regardless of their consumption. The increase, in line with the forecast CPI in Catalonia, translates into almost five euros more per bill over the last three years.
In 2024, the water bill rose by 11%, which meant about five euros extra every two months. In 2025, the increase was 5%. Now, in 2026, the rise has moderated to 2.9%. It is important to point out that the price of water supplied by ATL (Ter Llobregat) did not vary either in 2024 or in 2026, so the increase affects only the part managed by Aigües de Barcelona. In other cities outside the AMB, both public and private companies have also increased their tariffs. The water levy, collected by the Generalitat, is not rising for the moment, although it could do so if new budgets are approved.
The new tariff will come into force in January 2026. The main reason for the increase is inflation, with CPI forecast at 2.9% in Catalonia. In addition, Aigües de Barcelona is considering a possible increase in the cost of supply from ATL, although this has not yet been officially confirmed.
The water bill is made up of several items: 16% corresponds to municipal charges (sewerage and waste), 36% to supply by Aigües de Barcelona, 15% to the AMB levy, a further 15% to the Agència Catalana de l'Aigua (ACA) charge, 13% to the purchase of water from ATL, and the remaining 5% to VAT and other state taxes.
