Storage basins · 1,000–1,400 mm/year
Viticulture: reserve water before harvest
Wineries store winter water for supplemental irrigation. Exposed basins can exceed 1,200 mm/year evaporation.
Sector challenge
Yield and quality depend on summer irrigation under tightening restrictions.
Orders of magnitude
3,000 m² at 1,100 mm/year loses 3,300 m³. 88% cover preserves over 2,900 m³.
Solution
Modular HDPE cover, pour-in deployment, no framework.
Data-backed case study
3,500 m² irrigation basin in Occitanie: 4,025 m³/year gross loss, 3,542 m³ secured with Hexprotect AQUA cover (η = 0.88).
