Water Use

Water Use Totals

Per capita water use in the Water Authority’s service area – shown in green on the graphic to the right – has fallen from more than 200 gallons per person/day to about 150 gpcd over the past decade. The blue bars in the graph show that in 2013 total regional use of potable water was less than it was in 1990, even with a population increase of approximately 30 percent over that period.

The table below details regional water use (excluding recycled water) by month and year. It shows that total potable water use for the Water Authority service area for the 12 months ended June 2014 was up 3.5 percent compared to the year-earlier period. Urban (municipal and industrial) potable use for the same period was up 2.9 percent. For June 2014, total potable water use was up 0.1 percent over the same month a year earlier.
