Conserve water. The average family of four in the U.S. uses about 400 gallons (1,514 L) of water every day.[3] Make conscious choices to lower your consumption of water.
Take shorter showers or fill the bathtub only one-quarter to one-third full.
Turn off the faucet while you brush your teeth.
Install low flow faucets (taps) or aerators, low-flow shower heads, and low-flush toilets.
Run your dishwasher only when it is completely full.
Wash full loads of laundry in a washing machine. Choose a front-load machine if possible.
If you hand wash your car, park it on your lawn and use buckets and sponges. Use the hose to rinse. Use a hose nozzle to stop the water or turn the hose off between rinses. Keep in mind, however, that the soap and other cleaning products might go down the storm drain (if you have one), leading to pollution.
If you have a swimming pool, use pool covers to reduce evaporation and keep leaves out.
Plant drought tolerant landscaping, and consider xeriscaping. Maintain your outdoor irrigation and water no more than is necessary.
