  15. Cost summary and other considerations

  16. Summary of resources and production costs

  17. OUR WATER RESOURCES MUST BE SUSTAINABLE • The cost of production, an exponential increase

  18. OUR WATER RESOURCES MUST BE SUSTAINABLE • Growth of the Ter-Llobregat water supply • In the last 35 years: • resources: 20% • population:  40%

  19. ALERT ALERT ALERT ALERT ALERT ALERT OUR WATER RESOURCES MUST BE SUSTAINABLE • The threat of restrictions: a latent risk RESERVOIR CAPACITIES Ter: 398 hm3 Evolution of the water resources in the Ter-Llobregat system Llobregat: 213 hm3
