  • Italy was the biggest beneficiary of EIB resources for the water sector from 2016 to 2022, receiving €2.9 billion.

The European Investment Bank (EIB) has provided a €435 million loan to Acea with the primary goal of strengthening and improving infrastructure for more efficient and resilient water services. The transaction signed by EIB Director General of Operations Jean-Christophe Laloux and Sabrina Di Bartolomeo, Chief Financial Officer  today in Rome is the first, €235 million tranche of a loan totalling €435 million approved by the EIB Board of Directors.

The EIB is co-financing the 2023-2026 investment plan of Acea Ato 2, the Acea Group company responsible for managing water services in Rome and the surrounding area.
