Check every faucet in the house for leaks. A single dripping faucet can waste far more water in a single day than one person needs for drinking in an entire week. Don't wait to fix a drip. Each load of laundry uses between 27 and 54 gallons of water. To save water, select the appropriate water level for the size of your laundry.
Most washers now offer preset levels for small, medium, and large loads.
