A modern dishwasher can use as little as 15 litres of water for each wash. Compare that to around 63 litres that hand washing uses each time, or 150 litres if the dishes are rinsed as well, and you can see just how much water and money you could save†. Make sure you wait for a full load before you turn the dishwasher on though or you’ll end up wasting even more than hand washing.
You can save when using your washing machine too, remember that one full load uses less water than two half loads, and less energy
