HOW IT WORKS to operate 300 wastewater treatment plants and 600 pumping stations in Sardinia (Italy). “In the Mediterranean islands, water resources depend greatly on very fluctuating rains. Therefore, their management must ensure a balance between the conventional water and unconventional water originating from desalination to compensate for the lack of rain. In addition, in summer the greatest water needs due to tourism coincide with the driest season,” explains Luigi Patimo, Italy Country Manager at ACCIONA. Islas Pelagias (Lampedusa, Linosa y Pantellería) (ITALY) For decades, they were supplied by ships, like in Carthaginian times. Thanks to the project awarded to a consortium of com-panies led by ACCIONA, today the supply is guaranteed through modular osmosis desalination plants that has saved more than €240 million in 10 years, in addition to a more constant and durable supply. Before, no such thing existed, and when waves were high it was impossible to dock the tanker ships, so there were frequent shortages. The modular plants are located in Sataria and Maggiuluvedi (Pantelleria).
