Dishwashers typically use a relatively small amount of the overall household water consumption. Newer, more efficient models typically use less than 5.5 gallons of water per load, compared to about 10-15 gallons for older versions. For a family of four, this equates to about 1,000 gallons saved per year.
Washing machines use anywhere from 15 – 40% of overall household consumption for a family of four. Older models will use about 40 – 45 gallons per load, compared to the new High Efficiency ones, which use 14 – 25 gallons per load. Upgrading to a High Efficiency machine will save more than 6,000 gallons per year, while simultaneously saving energy, reducing fabric wear, and doing a better job cleaning your clothes.
