Water management

The sustainable management of site water where it is withdrawn, used and disposed of encourages the maintenance and improvement of water use efficiency, ensuring less waste and reduced environmental impact.

Ansaldo STS manages water resources with particular attention and over the years it has carried out initiatives to save water, including the installation of photocell faucets in Italy, projects to recover rainwater at the Riom site (France) and projects to replace the cooling towers with “dry” systems.

Ansaldo STS applies the “Water management guidelines” that Finmeccanica has formalised and applied to all companies with the aim of defining the methods to be followed by the group’s Italian companies for the sustainable management of water at their office and production sites.

Ansaldo STS’ water procurement sources include aqueducts and water tables where water is drawn through wells.

Water is mainly for civil use. Water consumption at the sites in Tito Scalo (Italy), Riom (France) and Batesburg (US) is very low.

The waste water produced at the sites can be classified, on the basis of its use upstream from disposal, as domestic (or similar) and industrial. All Ansaldo STS sites produce waste water that can be exclusively classified as domestic or similar, except for the Tito site. The Naples site uses an organic waste water treatment system. The sites use authorised disposal points.

Total water used [m3]  24,714  109,174 
DIFFERENCE [m3] 4,055  45,753 

The difference in the office sites is mainly due to the use of water for gardens and cleaning and because of evaporation.
