In our tests, we found that it took just over 12 gallons of water to wash four place settings by hand. In other words, hand washing used 5 times as much water as an efficient dishwasher, and 3.5 times more water as an average dishwasher. The more dishes you wash by hand, the more water youd waste.

How does a portable dishwasher drain?
