Alternative water resources plan

The Alternative Water Resources Plan aims to move towards sustainable and rational water management focusing on water saving, optimization and substitution by alternative water resources. The plan identifies existing water resources and their potential uses according to their characteristics (chemical and biological), dimensioned potential demand and provides city infrastructure necessary for their use. The plan provides a global map of alternative resources to drinking water in Barcelona and gives visibility to the water supply across the city. In addition, it ensures synergies between the different municipal and private operators in the city for improvement in supply.
