Water Footprint

Since 2015, Ferrovial has carried out a project consisting of the development of a water policy and 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 water policy and 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.

WATER POLICY

Ferrovial identifies water as a finite and irreplaceable natural resource. Directly linked to global change and an underpinning and essential element of the circular economy.

In its role as a consumer and  supplier of water-related services, Ferrovial promotes the following principles to all its stakeholders.

Principles

  • Compliance with water legislation and regulations in force, and also with the specifications of the international standards of reference and those set in-house by our organization, executing water management so as to attain the highest quality standards.
  • Support for the development of regulatory frameworks focussing on efficient and sustainable water use.
  • Responsible and efficient management of the resource, covering the whole of its integral cycle, facilitating social development and the conservation of ecosystems.
  • The search for solutions to the rising demand for potable water and deterioration of water quality due to pollution.
  • Setting indicators, goals, monitoring procedures and strategies to enable ongoing measurement and assessment of the degree of efficiency of the integral water cycle and its responsible use in the company’s direct operations, optimizing the resulting balance in the Group’s water footprint.
  • Support for the development and employment of new technologies enabling a more efficient use of water as a resource.
  • Inclusion of water usage and management in the company’s risk management strategy.
  • Publication of the results of the company’s integral water management.
  • Company engagement to enable access to clean water and sanitation for the population in developing countries.

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. The 2017 BWI index value is 5,482,743
  • 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). The 2017 WTI index value is -199,656,213
  • Water Access Index (WAI) , related to water supply projects within the Social Action Program. The 2017 WAI index value is -535,156

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. The company currently holds a B rating.
