The invention of the shower and the spread of its use has greatly reduced the consumption of water. The situation in Italy is, however, in any case critical. After Japan and Mexico, Italy ranks as the third country for importation, putting it ahead of the United Kingdom and Germany.
A person requires four litres of water per day. Obviously we use more than this for cooking and household use. The average daily consumption for a European family is around 165 litres. The Italian hydraulic footprint, that is, the amount of water used to produce goods and services, is equal to 132 billion square metres annually, or roughly 6,309 litres per day.
Italy consumes more than 250 litres per person each day, more than any other European nation. What measures can be taken to reduce this? Have you ever heard of domestic economics?
