The sustainable management of site water where it is withdrawn, used and disposed of encourages the maintenance and improvement of water use efficiency, ensuring less waste and reduced environmental impact.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 has conducted a number of water-saving initiatives. These include 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’s “Water management guidelines” are 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 office and production sites.

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

The use of water is mainly for civil purposes. Water consumption at the Tito Scalo (Italy), Riom (France) and Batesburg (US) sites is very low. These sites reduced their withdrawal of water substantially (-21.6%) from 2014 to 2016, as the Tito Scalo plant cut the amount of industrial water it used for fire drills and irrigation of green areas. The amount of water used for production decreased because electrical circuit cards are no longer rinsed.

Compared with 2015, withdrawal fell at the office sites as well (-11.1%); particularly affecting this result was the decrease recorded at the Naples site.

The water consumption per employee indicator shows a reduction of 24.7% at the production sites and a 27.1% reduction at the office sites, both due to the combined effect of reduced consumption and increase in the number of employees.
