Water is an essential element to life. The human body contains about 60 to 70%.
He had always understood the importance since the dawn of prehistory, so that, around the water, arose many myths and forms di culto.
L’uomo ha sempre costruito le sue abitazioni in prossimità di una sorgente di acqua perenne. Dove non trovava fiumi o sorgenti, si è procurato l’acqua scavando pozzi ( i Nuragici ) e costruendo acquedotti ( i Romani ).
Oggi, il consumo di acqua potabile varia, mediamente, tra circa 100 litri/giorno, per un abitante dei piccoli centri, fino a oltre 300 litri/giorno, nelle grandi città.
In Italia c’è una sola rete di distribuzione dell’acqua “potabile” per tutti gli usi, con gravi carenze locali che aumenteranno sempre più nell’immediato future.
would, therefore, desirable to have a policy of rationalization and, also, a second network supply of water for human consumption.
In this case, the water that comes from the tap hours, would be used as a less noble purposes, but also necessary, such as those requiring clean water, but with less stringent physical and chemical parameters (that would cost less ).
While the water for drinking and cooking, would pure water source.
This will avoid the high use of mineral waters, with enormous benefits for citizens (almost zero cost), and the environment : Less plastic bottles, to supply less effort (think of the elderly who do their shopping on foot), less than road transport, less car accidents , etc...)
