Today we have tested how much more we spend water if we wash our hands "lazy" or "quickly but properly". Test group (10 pupils) spent 22 litres (2,2 l/pupil) compared with 4,5 litres (0,5 l/pupil). The conclusion we made: You have to wash your hands properly and with soap but not using too much water (the faucet not at maximum).
Have a nice energy saving week!
