The indicator in term of energy per unit of length is useful in account of the cost for the water distribution: it
must be considered that the drinking water is transferred by a pressure system while the sewage is collected by
gravity. For the distribution network, the value was equal to 8.3 kWh/m, while for the sewage network, it was 0.9
kWh/m. The consumption of thermal energy has been evaluated for the Water treatment phase as the heat to warm
the locals and the laboratory of the main WTPs on the Po river, equal to 4,9 GWh/y from the local district heating of
Turin. In the phase Wastewater treatment the amount of thermal energy used is 51,197 MWh/y of which 18,780 MWh/y are produced from the combustion of biogas.
