Which uses less water for washing dishes?

Using a dishwasher generally uses less water than hand-washing dishes. A typical dishwasher uses about 10 to 12 gallons (38 to 45 liters) of water per load, while hand washing dishes can use up to 27 gallons (102 liters) of water. However, the water consumption can vary depending on the model of the dishwasher and how efficiently the water is used. Using a water-saving dishwasher and selecting the right cycle for the load can further reduce water usage.
