Catalonia: the Ebro and Segrià under evaporation pressure
In Catalonia, farm reservoirs lose up to 1,300 mm of water per year on exposed surfaces. Structural drought, irrigation quotas and tramontana: every stored m³ must be preserved.
Local hydric context
Ebro, Lleida, Segrià and inland Costa Brava: fruit growing, horticulture and hill reservoirs. Catalan Water Agency and SMC document recurring restriction campaigns.
Orders of magnitude
An 8,000 m² basin at 1,300 mm/year loses 10,400 m³ to evaporation. With Hexprotect AQUA cover (88% conservative), over 9,100 m³ remain for irrigation.
Technical solution
UV-stabilised HDPE modules resistant to tramontana winds, pour-in deployment. Measurable evaporation cut and photosynthesis blocked.
