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The sustainable management of site water where it is withdrawn, used and disposed of encourages the maintenance and improvement of water use efficiency, ensuring less waste and reduced environmental impact.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 Tito Scalo, Riom (France) and Batesburg (US) production sites is very low. Moreover, there was a steady reduction in water used by these sites in 2014, thanks to the decrease in industrial water used at the Tito Scalo production site for fire-fighting exercises and irrigation of the green areas. The portion of water used for production activities (rinsing electronic cards) also decreased as the company discontinued this activity during the year.

Conversely, water withdrawn by the office sites increased, especially in Naples, Pittsburgh and Piossasco.

The wastewater 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 wastewater that can be exclusively classified as domestic or similar, except for the Tito site.
All the domestic or similar wastewater is discharged into the sewers. The Naples site uses an organic wastewater treatment system. The sites use authorised disposal points: the Batesburg and the Tito Scalo sites’ points are monitored.
Industrial wastewater, produced only at the Tito Scalo site, decreased due to favourable weather conditions that allowed a large reduction in consumption. The rinsing water is discharged directly into a consortium sewer while the first rinse water is collected in an external tank and eliminated as waste.
