The Government of Catalonia has agreed to pay Acciona EUR53.8 million (US$61.7 million) for the termination of the Aigües Ter-Llobregat (ATLL) concession. ATLL manages a water supply network in the Ter-Llobregat region of Catalonia utilised by more than five million Catalans in 120 municipalities, including Barcelona.

The government initially attempted to cancel the 50-year concession, awarded in 2012, without making any payments to Acciona, ignoring the company's demands for substantial compensation. This was on the grounds that the flawed tender process invalidated the awarding of the contract, as ruled by the Supreme Court of Spain, and thus that it is null and void.

However, the Superior Court of Justice of Catalonia resolved at Acciona's request that the Supreme Court's ruling acknowledges the existence of the ATLL contract, thus it must be annulled, rather than declared null and void.

EUR46 million (US$52.7 million) of the EUR53.8 million that the government has agreed to pay are taxes that the concessionaire has already paid and that it must claim from the corresponding tax agencies. The amount does not include any compensation that Acciona has requested for damages.
