Progress toward mandatory water reduction*

California Water Service Company Westlake water use decreased by 33.35 percent between June 2015 and February 2016 — the nine months of the initial statewide conservation mandate — but the agency failed to meet a 36 percent reduction.
38.267
billion gallons consumed
over the same months in 2013.
25.505
billion gallons consumed
between June 2015 and February 2016.

*: Approved by the State Water Resources Control Board in 2015, the reduction target was meant to achieve a 25 percent reduction in water use statewide. It is tied to an average July through Sept. 2014 daily per capita residential water use rate that placed water agencies into nine tiers.

About the data: This data is for urban water suppliers and is based on the the most recent reports submitted to the State Water Resources Control Board. Since the gallons of water used per person per day measurement does not take into account rainfall, temperature, humidity and population density, the State Water Resources Control Board discourages comparisons between water suppliers.
