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.
