Management of water services

We are the leading Italian operator in the sector of integrated water services, for the number of residents served, and operate in five regions - Lazio, Tuscany, Umbria, Molise and Campania - through subsidiary and investee companies. We are also present in Latin America under partnership agreements.

Integrated and sustainable water management 

The integrated management of water resources begins with a careful analysis of springs and groundwater. We check and ensure the quality of the water throughout its journey: from catchment to distribution. Similar attention is given to the wastewater collection and treatment phases.
We are committed to sustainable management of the resource, we return the purified water to the environment to continue its natural cycle. All this is possible thanks to an efficient management of infrastructures, process digitalisation and the competence of our operators.

Management of the integrated water service is our most important business, which is why we have included in our Business Plan investments totalling 1.9 billion Euro to develop this area.
