The average daily water consumption is approximately 220 litres per person. For a family, because of economies of scale, the total consumption will be less than the sum.
The last census on water for civil use by Istat dates to 2012. In this year, the daily consumption of water supplied to users was 241 litres per inhabitant. A sobering figure is the volume of leaks from municipal water distribution networks which amount to 37% of the total volume fed into the network, that does not reach end users.
The average consumption of an average Italian family is approximately 200 cubic meters per year.
Only a small part of the total is used for cooking and drinking while most of it is used for non-food purposes: in the bathroom, for washing clothes and dishes, for watering plants …
The value can therefore vary from family to family.
