The sustainable management of site water during withdrawal and use encourages the maintenance and improvement of water use efficiency, ensuring less waste of the resource and reduced environmental impact.
The water is mainly used for sanitary purposes and for the operation and cooling of air conditioning systems; in certain locations it is also used for watering the green areas. Hitachi Rail STS’s water procurement sources include aqueducts and water tables where water is drawn through wells. To reduce water consumption, Hitachi Rail STS has installed devices that mix water and air or, alternatively, photocells or timed controls that effectively control the water flow, in order to minimise the waste of the resource.
Rainwater recovery projects at the Riom plant in France and the replacement of cooling towers with “dry" systems also contribute to sustainable water management.

WASTE WATER
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 Hitachi Rail STS sites produce waste water that can be exclusively classified as domestic or similar, except for the Tito site. All the domestic or similar waste water 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’ disposal points are monitored.
