Here are some interesting facts about water conservation:

* Less than 2% of the Earth's water supply is fresh water.

* Landscaping accounts for about half the water Californians use at home. Showers account for another 18 percent, while toilets use about 20 percent.

* The average American uses 140-170 gallons of water per day.

* There are 7.48 gallons in a cubic foot of water. Therefore, 2000 cubic feet of water is 14,960 gallons.

* An acre foot of water is about 326,000 gallons. One-half acre foot is enough to meet the needs of a typical family for a year.

* It takes 3.3 acre feet of water to grow enough food for an average family for a year.

* If you water your grass and trees more heavily, 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 does not need water. If it stays flat, it does need water.

* Never put water down the drain when there may be another use for it such as watering a plant or garden.

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

* Public water suppliers process 38 billion gallons of water per day for domestic and public use.

* Approximately 1 million miles of pipelines and aqueducts carry water in the U.S. & Canada. That's enough pipe to circle the earth 40 times.
