In Spain, rainwater collection basins in Teruel and Lleida secure irrigation for orchards during seasonal rainfall fluctuations and droughts. High-quality geosynthetics provide long-term waterproofing, reduce water loss and support reliable agricultural production.

Efficient water storage is essential for agriculture, particularly in regions where water resources are scarce. In Spain, farmers increasingly struggle with seasonal rainfall fluctuations and prolonged droughts, making sustainable irrigation solutions crucial. To secure the water supply for their orchards, large-scale rainwater collection basins were constructed in Teruel and Lleida. These reservoirs enable efficient irrigation, ensuring optimal growing conditions despite climatic challenges.
The use of high-quality geosynthetics plays a vital role in this process. They provide long-term waterproofing, reduce water loss, and lower operational costs. This innovative approach not only enhances farm profitability but also supports efficient and reliable agricultural production.

To meet the rising irrigation demand in Spain’s dry regions, modern water storage systems were developed. Large-scale irrigation ponds ensure a stable water supply throughout the growing season.
Locations: Teruel & Lleida, Spain – Regions with insufficient natural precipitation for orchard irrigation.
Objective: Minimise water loss and ensure sustainable irrigation through long-term rainwater storage.
Technical solution: Naue Carbofol® geomembranes provide an impermeable seal, while Secutex® geotextiles protect the sealing system from mechanical damage and enhance reservoir stability.
Result: A reliable, cost-efficient water supply that reduces dependence on external sources and stabilises agricultural production.
The installation process is key to ensuring the longevity and efficiency of the rainwater collection basins. It begins with soil preparation, where the subsoil is compacted and sharp materials removed to prevent damage to the geomembrane. Next, a Naue Secutex® nonwoven geotextile is placed over the prepared ground. This protective layer prevents punctures and dust contamination before the Carbofol® geomembrane is installed. The membrane is joined using a double-welding method, creating an intermediate air channel for precise leak testing via air pressure. To maintain stability during installation, sandbags or other securing methods prevent wind uplift, ensuring the geomembrane remains in place until final covering layers are applied. This structured approach guarantees the long-term functionality of the reservoirs.
With innovative irrigation solutions, geosynthetics play a crucial role in efficient water management. Rainwater collection basins with advanced sealing systems enable long-term crop yields. Thanks to modern technology, farmers benefit from a secure irrigation supply and increased resilience to climate variability.
Reduced water losses and lower maintenance requirements help decrease operating costs, while the reservoir provides a reliable water supply and reduces dependence on external sources.
UV resistance, chemical stability and mechanical strength are highlighted as factors supporting the long service life of the system.
The Carbofol® geomembrane sheets are joined using a double-weld seam. The intermediate air channel allows precise leak testing by air pressure.
