Run your dishwasher only when it's full. Don't pre-rinse dishes - tests show pre-rinsing doesn't improve dishwasher cleaning, and you'll save as much as 20 gallons of water per load. When you buy a new dishwasher, look for one that saves water. Water-efficient models use only about only about 4 gallons per wash.
