Conservation Tips

Landscaping accounts for about 50%the water Californians use at home. Showers and baths account for another 13%, while toilets use about 10%. Faucets use about 9% and washers also use about 9%. The remaining 9% is from leaks. Thus, landscape is the easiest place to save water. 

If every household in America had a faucet that dripped once each second, 928 million gallons of water a day would leak away. A leaky faucet can waste 100 gallons a day.

One flush of the toilet uses about 1 ½ gallons of water. An average family of four uses about 250 gallons of water per week just by flushing the toilet. Avoid flushing the toilet unnecessarily. Dispose of tissues, insects and other such waste in the trash and NEVER in the toilet or it could clog.

The average 10-minute shower uses about 25 gallons of water. Take short showers instead of baths. A full bathtub requires about 36 gallons of water.

You use about 5 gallons of water if you leave the water running while brushing your teeth. Don’t leave the water running when brushing your teeth or shaving. Get in the habit of turning off the water when it’s not being used.

If you water your grass and trees longer, but less often, this saves water and builds stronger roots. Water your lawn only when it needs it. If you step on the grass and it springs back up when you move, it doesn’t need water. If it stays flat, it does need water.

Water lawns during the early morning hours, or evening when temperatures and wind speed are the lowest. This reduces losses from evaporation.

Run your dishwasher and washing machine only when they are full.

When washing a car, use soap and water from a bucket. Use a hose with a shut-off nozzle for rinsing. Never put water down the drain when there may be another use for it such as watering a plant or garden, or cleaning.
