Hydropreserve · Southern Europe
Modular floating covers for lakes, reservoirs and irrigation basins — up to 96% less evaporation (Nevada field reference). Supplied across Europe by Hydro Innov (AWTT distributor).

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

* Conservative simulator coefficient: 88% evaporation avoided (η = 0.88). Maximum measured: 96% — AWTT / Hexprotect AQUA field monitoring, Nevada (2024). 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.

→Hydropreserve is Hydro Innov's specialist European showcase — supply and installation of Hexprotect AQUA (AWTT) floating covers across Spain, France, Italy and Portugal.
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 88% as a conservative default coefficient — an on-site audit refines the figure for your facility.
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.
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.
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.
Yes. Hexprotect AQUA modules are moulded in UV-stabilised high-density polyethylene (HDPE). Their aerodynamic hexagonal geometry limits wind uplift: they stay in place in strong winds on Mediterranean coasts, steppes and plateaus. They also withstand freeze–thaw cycles without degradation — decisive for mountain basins or winter storage.
HDPE floating modules allow air circulation beneath the cover while removing the appearance of open water: birds no longer land or drown on reservoirs, reducing avian mortality. The opaque surface also stabilises bacteriological water quality — a frequent regulatory argument for municipalities and large projects.
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.
