How much water do we use?

earthRemember that 7.48 gallons = 1 cubic foot of water

The average Californian uses about 192 gallons per day.

Typical water-use patterns vary according to geography, climate, lot size and other factors. As a general rule, per capita water use is higher in hotter, inland regions than in cooler, coastal locations.

If you live in a single-family home, 50% or more of the water you use every day may be going to your lawn or landscaping. Since a thirsty lawn can be the largest user of water in a home, finding ways to save water outdoors can make a big difference in your water bill.

Indoors, activities such as bathing, cleaning and flushing toilets account for more than half of all water used inside the home. Toilets alone account for about 26% of typical residential water use.
