Water Footprint

Since 2015, Ferrovial has carried out a project consisting of the development of a methodology for the calculation and reporting of water consumption and associated effluents. In addition, we analyze the risks and opportunities related to water, knowing our Water Footprint.

Ferrovial has a methodology to calculate the Water Footprint that covers all companies in the group that have operational control. This water methodology is specific to Ferrovial and has been developed based on the principles of The Water Footprint Assessment Manual (WFM), the Global Water Tool (GWT) and GRI-G4. These indices consider aspects such as the water stress of the country, impact on water resources, impact on vegetation management, quality and accessibility to water. In this way the impact on this resource is quantified.

METHODOLOGY

The Ferrovial Water Footprint is composed of three indices:

  • Business Water Index (BWI) , related to the consumption of water and its discharge carried out in activities developed by Ferrovial.
  • Water Treatment Index (WTI) , related to the impact of the water treatment activity on resources (WWTP, Wastewater Treatment Plant, iWWT, Industrial Wastewater Treatment Plant, PWTP, Potable Water Treatment Plant, and SWDF, Seawater Desalination Facilities).
  • Water Access Index (WAI) , related to water supply projects within the Social Action Program.

In 2016, we published for the first time data from Water Footprint with a 100% scope. In addition, in the same year the company first presented itself to the Water category of the CDP index, obtaining an A- rating, a recognition of the Company’s strategy and performance.
