If everyone in the United States could manage to use just one less gallon of water per shower every day, we could save some 85 billion gallons per year. By keeping the shower pressure lower or by making your showers a few seconds shorter. If someone in your family likes to shave with water running in the basin, they probably use at least one gallon per minute, most of it wasted. A stoppered basin needs one-half gallon or so of water for adequate razor rinsing. Pipes Wrap hot water pipes with insulation to avoid waiting for hot water.
Faucets 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. Check the water taps in your home to see if they all have aerators or spray taps. An aerator mixes air with the water, which not only cuts the flow but reduces splashing. The spray tap is similar, but can also swing from side to side like a tiny showerhead.
