Dishwashers are also a large water consumer.
Both of these machines take up a very significant part of the water bill every month. If you are just washing a pair of socks and a shirt, make sure that you change the setting of your machine to a small load. This can save up to 30 gallons per load. For dishwashers, wait until the entire machine is full to wash dishes. If you only have a few dishes you wish to clean, do them by hand.
