ABG provides leak detection solution for tropical fruit irrigation basin on El Hierro

As the first cold weather of the winter starts here in the UK it is a good time to imagine being in warmer climes! The Balsa de El Golfo reservoir basin is located on the small island of El Hierro (the most westerly of the Canary Islands) and with a capacity of 120,000 cubic metres, the basin provides irrigation for 200 hectares of tropical pineapple, banana and subtropical fruit crops on which the El Hierro economy depends.

Over 22,000 sq m of ABG’s Pozidrain geocomposite was specified for the leak detection and drainage layer and to alleviate the risk from pore water pressure causing wider spread damage in the event of a tear. The 6mm deep cuspated drainage core provides a controlled in-plane flow rate that is equivalent to an approximately 150mm thick layer of stone, whilst the integral geotextile bonded to the upper surface of the core serves to filter and prevent any sediment from blocking the drain.
