I was in a discussion earlier today. It seems we personally use, at home in UK, about double the proposed personal limits [according to my very detailed water bill]. But ... that includes a large bubble-bath, dishwasher and washing machine.
i doubt Armageddon is yet upon us, but we can/should try to help. This was in our shower and bathroom in Stellenbosch last month ... we would fill 3/4 of that shower bucket, that they then recycled.
KEEP CALM, AND CARRY ON ... ECONOMICALLY
.... And drink WINE, not water!
