I’m confused when I hear people say they’re saving water by washing their dishes by hand because when I bought my first dishwasher two years ago, I did my research and found that by buying a AAA-rated machine I would be saving not only time, but water and electricity too. Still, the myth that dishwashers are water-gobbling evils prevails, and so I was grateful and relieved to read in The Guardian that it’s now official, get a dishwasher and save water.
A study by Waterwise, an NGO dedicated to reducing water wastage, shows that washing dishes by hand is wasting millions of litres of water every day in the UK.
