Water consumption (m3)

Per capita consumption (m3)

  • The objective of reducing per capita consumption by 5% during the 2010-2012 three-year period was not achieved because of a series of leaks in the water pipes of some sites in recent years, which have now been rectified.
  • In 2012, 588,723 m3 of water was consumed, mainly for hygienic and sanitary purposes and for the operation and cooling of air conditioning equipment; only at some sites was water also used to water the green spaces. Moreover, 420,752 m3 of industrial water from the Po River, in Italy, and Lake Lugano in Switzerland, was used as industrial water for the cooling systems. As such, a total of 1,009,475 m3 of water was withdrawn.
  • Almost all of the water consumed comes from municipal or state water mains; only an extremely small quantity of the water consumed, equal to 0.1%, is groundwater, which is used only rarely, above all in the summer, in Austria (200 m3) and Germany (170 m3). In addition, 240 m3 of rainwater was collected using special tanks at some sites in Germany and then reused.
  • The increase in consumption recorded in Switzerland in 2012 was due to the greater use of water for the DPC cooling system. The high per capita consumption level in Italy was due to the fact that many air conditioning systems at the various sites are cooled using water.

To reduce water consumption some Group sites have systems that mix water and air; alternatively, there are photocells or timed controls that make it possible to control water flows and reduce the waste of this resource to a minimum.

In order to reinforce and demonstrate its commitment to reducing water consumption, in 2011 the Group signed the CDP Water Disclosure Project, an international initiative that seeks to raise the awareness of companies as regards the sustainable management of water.

Initiatives to reduce water consumption in 2012
COUNTRYTYPE OF INITIATIVE
ItalYSustainability assessments were carried out on all of the buildings included in the System;
these assessments also include the analysis of water consumption and the definition of
measures to reduce consumption. In addition, a technical comparison was made between air
and water condensation which showed that - for medium-high levels of cooling power - water
condensation is preferable as it consumes less electricity.
