Our state government has suggested that we limit ourselves to 155 litres of water per day per person. We come in under that, just, but then we don't have a garden to water. I felt guilty when I read Daniel's post, but then it is not really apples and oranges. We are two people here all the time.
Our consumption is around 295 litres per day, so that is 148 litres per day each.
The dishwasher is used almost daily but it uses very little water, far less than any other model we have had. It is nearly always full, but if not, I will put in perhaps some glasses from the auto trolley that are getting dusty or bits of the range hood.
Our washing machine is a top loading model, three years old, so not good to change for water saving reasons if other environmental matters are taken into account. Perhaps six loads of washing a week.
R showers twice a day, I would average 1.5 times a day over a week. They are rarely long showers, usually less than three minutes. We have tried water saving shower heads of many varieties and hate them. We have tried flow restrictors and hate them also.
Where we really go wrong is no fault of ours. Ten litres of run off before hot water arrives at the tap.
We don't use hot water for handwashing. It is such a waste of water and time waiting.
But say four showers, twice hot water at the sink is sixty litres, or thirty each. Make it forty as we might once a day each want hot water at the bathroom basin. Subtract that from 147 litres and we are down to 107. With water saving showerheads, we could perhaps knock it down to one hundred, but I ain't doing that.
I grew up in the country where we often lacked water and bathed in a couple of inches of muddy water and you would have a complimentary tadpole in your glass of water. I didn't expect to almost live in the city proper of Melbourne in 2008 but if I had imagined it, I am sure I would have expected plentiful water.
