A 2011 study of a sampling of 735 California homes across ten water districts found that the weighted average annual total water use of these homes was 132,000 US gallons (500 m 3) per year or 362 US gallons (1.37 m 3) per household per day. [44]
The equivalent average use per person is 52.1 gpcd (gallons per capita per day) or 197 liters per capita per day. Because the distribution of indoor use in the sample of homes is positively skewed, a more appropriate measure of central tendency is the median, which is about 125 gphd (or 472 lphd). Toilet flushing is the largest indoor use of ...
Data on functional metrics show schools' use between 3 and 15 gallons per school day per student for indoor use. and between 4.7 and 23.6 gallons/student/day in Santa Fe, New Mexico. There are 389,000 school buildings in the U.S. with the total floor space of 12,239 million square feet.

The recommended daily amount of drinking water for humans varies. [1] It depends on activity, age, health, and environment.In the United States, the Adequate Intake for total water, based on median intakes, is 4.0 litres (141 imp fl oz; 135 US fl oz) per day for males older than 18, and 3.0 litres (106 imp fl oz; 101 US fl oz) per day for females over 18; it assumes about 80% from drink and 20 ...

This is an average amount per capita of 1.385 Gm 3 /yr., or 3.800 liters per person per day. [42] On average 92% of this is embedded in agricultural products consumed, 4.4% in industrial products consumed, and 3.6% is domestic water use. The global water footprint related to producing goods for export is 1.762 Gm 3 /y. [43]
On March 20, 2023, Trinity Lake was losing 1 billion gallons per day to Flow Augmentation. [59] This happened during historic drought, while Trinity was at only 50% of historical average, and all other major California lakes were at least 91% of historical average. The Trinity River Restoration Program is responsible for regulating the flow. [60]
