November Conservation Data

2015 was a groundbreaking year in the number of laws, and legislation passed aimed at solving the drought.  It was a also a flagship year in the amount of per person water use reduction that that took place.  The long and short of it is that Californians saved a lot of water and are conscious of their current drought environment.   Here we take a look at the numbers to provide a quantitative view of what happened this winter with water usage.

  • For June through November, the cumulative statewide reduction was 26.3 percent, compared with the same months in 2013. That equates to over 1 million  acre-feet, putting the state more than 80 percent of the way to meeting the 1.2 million acre-feet savings goal to be achieved by February 2016.
  • Statewide water savings for November 2015 was 20.3 percent, a decrease from October 2015’s 22.3 percent savings.
  • Statewide average for November 2015 was 75 gallons, a significant decrease from the 87 residential gallons per capita per day reported for October.

Conservation Must Continue Through Winter

Despite recent rain and snow, most of California is still experiencing severe drought. Residential water users are urged to keep up their efforts to conserve through the winter months. That includes complying with urban water supplier directives to switch to watering schedules of once a week as well as a prohibition against watering during a rain event and 48 hours directly following a rain event.


In his April 1, 2015 Executive Order, Gov. Brown mandated a 25 percent water use reduction for cities and towns across California. In May 2015, the State Water Board adopted an emergency regulation requiring an immediate 25 percent reduction in overall potable urban water use. The regulation uses a sliding scale for setting conservation standards, so that communities that have already reduced their R-GPCD through past conservation will have lower mandates than those that have not made such gains since the last major drought.

The State Water Board tracks water conservation for each of the state’s urban water suppliers (those with more than 3,000 customers) on a monthly basis, but compliance with individual water supplier conservation requirements and the statewide 25 percent mandate is based on cumulative savings. Cumulative tracking means that conservation savings will be added together from one month to the next and compared to the amount of water used during the same months in 2013.

California has been dealing with the effects of an unprecedented drought. Every Californian should take steps to conserve water.
