ACCIONA sustainably manages water at each of its treatment stages, and is committed to ensuring a global distribution of this resource with optimal quality conditions.

So we take part in water's journey from the point it is collected, its purification, the maintenance and control of water storage and management of distribution networks, to supplying water to the population and control of sanitation networks, treatment of urban and industrial waste water and water reuse.

All our processes and facilities are run through tracking and automation equipment, which require specialised maintenance, upgrades and continuous management to optimise water treatment plants and processes. We use all the company's departments to be more competitive and to optimise designs with the aim of ensuring sustainable water management.

  1. Water collection from different sources
  2. Desalination: Removal of salt and other minerals from sea water or brackish water to make it fit for irrigation or human consumption
  3. Purification: Water treatment for human consumption
  4. Distribution: Maintenance of the water distribution network
  5. Water supply to populations and agricultural irrigation
  6. Maintenance of the sanitation network
  7. Water purification: Removing pollutants from waste water so as to achieve optimum quality to return the water to the environment
  8. Water reuse: Tertiary treatment for use in agriculture, urban parks and other activities
