Drought is the new normal

Watering basin dried out by drought — the flock gathers around a reserve reduced to cracked mud. Sicily, summer 2022.

In Andalusia, Catalonia, the Po Valley or Occitanie, operators lose thousands of m³ yearly to evaporation from storage basins.

* Evaporation reduction: 96% — from AWTT / Hexprotect AQUA field monitoring on an industrial basin in Nevada (2024), under extreme arid conditions. In Europe, performance varies with wind and geometry (80–96%).

Conserved water is an irreplaceable resource — its value goes far beyond the price per m³ when supplies run short.

Frequently asked questions

What evaporation reduction is realistic? +

Up to 96% measured on an industrial basin in Nevada in 2024 (extreme arid conditions, AWTT / Hexprotect AQUA field reference). In Europe, depending on wind, basin geometry and sun exposure, performance typically ranges from 80 to 96%. The simulator applies 96% as a high reference — an on-site audit refines the figure for your facility.

Does the calculator replace a hydraulic study? +

No. It provides an order-of-magnitude estimate to raise awareness and qualify a need. A study or on-site audit accounts for the actual basin shape, inflows (rain, runoff), water quality, operational constraints and the real cost of water in your context — essential before investment.

Who installs the covers? How does deployment work? +

Hydro Innov delivers Hexprotect AQUA modules directly to your site. There is no conventional installation: your teams simply open the transport bags and pour the elements onto the basin or reservoir. Once on the water, the patented hexagonal modules position and interlock themselves thanks to their shape — no further human intervention, no load-bearing framework and no long-term specialist crew. One operator can cover thousands of m² per day.

Can the cover eliminate chemical treatments? +

Yes — it is a major lever for preserving the resource. By blocking light at the surface, the cover prevents photosynthesis and therefore algae and cyanobacteria growth. The need for algaecides, chlorine or other anti-algae chemical treatments drops sharply. Stored water quality is stabilised passively, with no recurring chemical input.

Does the cover withstand wind and frost? +

Yes. Hexprotect AQUA modules are designed to stay in place in strong winds common on exposed basins (steppes, Mediterranean coast, plateaus). They also withstand freeze–thaw cycles without functional degradation — a decisive advantage for mountain basins or winter storage.

Does the cover protect wildlife? +

The covered surface no longer appears as open water to birds: floating modules greatly reduce perching and avian mortality risk on reservoirs, while preserving the stored water volume. This is a frequent regulatory and environmental argument for municipalities and large projects.

What is the return on investment (ROI)? +

Depending on surface area, climate and local water cost (or resource value during restrictions), payback is typically 3 to 5 years — sometimes less on large agricultural basins with high evaporation. Every cubic metre not lost to evaporation is water you already paid to store or treat.
