How is water wasted and systems reused

Sanitary technology portal: water recycling / gray water

in memory of: As so-called gray water, the reuse of shower and bath water offers largely unused possibilities to replace drinking water in larger quantities in the house. The techniques for treatment are mature and remarkable water quality can already be achieved.
Grauwasser doesn't really deserve its name, because the perspectives are anything but dreary and gray. Gray water comes from the bathtub, shower and hand basin and does not contain faeces (because then it would be "black water"). According to the European standard 12056-1, it also includes highly polluted wastewater from the kitchen and washing machines. However, only the first three areas are suitable for further use. This can replace 50 percent of the drinking water requirement in the household - by using gray water to flush toilets and water the garden.
