There’s a bit of fuss about the new water target of 155 litres per person per day.
(It seems particularly fussing were people on talkback radio with big families who couldn’t quite grasp that it’s per person not per household.)
I have an efficient shower head, and generally have sub-4-minute showers, and have a garden that doesn’t need watering — except the shower warmup-time grey-water which goes on the lawn. I don’t know how the nature strip and front lawn stay so green.
The car, naturally, never gets washed, though I occasionally use a little water to remove bird poo. The toilets are both dual-flush, though not particularly new/super-efficient.
Each week the washing machine runs perhaps 5 times; the dishwasher 2-3 times, hand washing the other stuff 2-3 times (though I confess recently I managed to go a full week without handwashing anything).
According to my last water bill, our household sits at 207 litres per day. Domestic arrangements mean there are 13 “person nights” spent in the house per week, so unless my maths is askew, that’s 111.5 litres per person per day. And that’s almost without even trying.
So a target of 155 per person per day? No big issue… at least, not for me. Though I’m sure it’s harder for households with thirsty gardens and where lots of people are at home all day.
