This change was made up as follows: slight drop in investments in the integrated water service (-respect to 2013 corresponding to around Euro 3.5 million) essentially due to a reduction in the measures on aqueducts partly offset by an increase in investments in new treatment plants; decrease in the investments with regard to waste management services (-21% with respect to 2013 corresponding to around Euro 1.5 million) due to the end of the work regarding the anaerobic digestion and waste selection plants, partly offset by the increase in investments in the separate waste collection sector thanks in particular to the launch of construction of the underground mini drop- off points in Bologna; slight drop in the investments regarding energy services (-4% with respect to 2013 corresponding to around Euro 1.5 million) due to a reduction in the investments on the district heating and 38 industrial co-generation network partly offset by the increase in investments on gas plants and networks.
