The volume of water abstracted for drinking use amounted to 9.5 billion cubic meters in 2015, broadly stable compared to 2012 (+0.3%)<\/p>\n
84.3% of the water abstracted for drinkable use derived from fresh groundwater (48.0% from well and 36.3% from spring), 15.6% from fresh surface water (9.9% from artificial basin, 4.8% from river and 0.9% from natural lake) and the remaining 0.1% from sea or brackish waters.<\/p>\n
Nearly one third (33.0%) of the water withdrawn came from treatment plants so as to ensure the drinking water standards.<\/p>\n
8.3 billion of cubic meters of water for drinking use were placed in the municipal distribution networks: 375 liters per capita per day, with a slight decrease of 0.4% compared with 2012.<\/p>\n
220 liters per capita was the quantity of water daily delivered by public water supply to the users (21 liters less than 2012). A total volume of 4.9 billion cubic meters is necessary to meet the drinkable needs of
\nthe territory.<\/p>\n
In 2015 total water losses amounted to 41.4% of the water in input in the supply network, indicating a worsening compared to 2012, when the indicator was 37.4%.<\/p>\n
The real losses, after deduction of customer meter inaccuracies, systematic data handling errors in customer billing systems and unauthorized consumption, were equal to 38.3% of the volume input in the network. It was a huge volume, equal to 3.2 billion cubic meters which, upon estimating 80 m3<\/sup> per inhabitant each year, represented the yearly water necessity for about 40 million people.<\/p>\n All regions showed, although with different levels, a general deterioration of the losses level in water supply networks, with the exception of Valle d’Aosta and Piemonte.<\/p>\n For information<\/strong><\/p>\n Stefano Tersigni
