Water is a precious good and the way it is used affects population increase, pollution and environment.
Water management is essential for the safeguard of biodiversity and the development and well-being of society. High water consumption rates compared with locally available natural flows can cause water scarcity. Enel constantly monitors all production sites located in water scarcity risk areas to achieve an efficient water management. The mapping is based on the following analyses:
- Mapping of areas with potential water scarcity: as regards countries whose average renewable water resources per capita is lower than the level established by FAO, production sites with water scarcity are detected also by means of specific software like that developed by the World Business Council for Sustainable Development;
- detection of critical production sites, whose water supply comes from freshwater sources;
- enhanced management efficiency by modifying plants or processes – when necessary – also aimed at improving waste water and sea water supplies.
Waste water can come from industrial use and meteoric water presenting potential oil pollution collected within thermal plants. After its treatment, which always takes place when it is discharged to surface water, it is partly used within these plants, helping meet the needs for industrial use. The rest of the waste water is discharged in water bodies.
