About the data: These charts show the daily per capita residential water use rate in California as calculated by the State Water Resources Control Board. The charts cover the July 2017 reporting period, and are compared to the previous month unless specified. Since the per capita measure (which reflects gallons of water used per resident per day) does not take into account rainfall, temperature, humidity and population density, the State Water Resources Control Board discourages comparisons between water suppliers.
