The district’s annual, renewable average water yield is approximately 30,000 acre feet. The majority of the district’s water is sold to its local municipal partners who manage water resources for their respective constituents. The district also operates small retail, secondary and wastewater systems. In addition, the district is federally-mandated to contribute water resources for environmental purposes. Allocations of the district’s water source are noted in the following chart.
Public community water system use throughout Washington County includes residential, commercial and industrial allocations, as outlined in the following chart prepared by the Utah Division of Water Resources.
Latest estimates prepared by the Utah Division of Water Resources report Washington County’s culinary residential water use was 144 gallons per capita per day (GPCD) with 63 GPCD for indoor use and 81 GPCD for outdoor use in 2013.
GPCD is a common metric used to measure water use. States and cities use GPCD numbers primarily to track use for planning purposes and to measure conservation accomplishments. Since there is not a national standard for calculating GPCD, numbers should not be used to compare water use efficiencies between states and municipalities. Each measuring entity sorts through dozens of variables and determines what to include and omit from their calculations, which creates substantial differences in the numbers.
Washington County’s water use has decreased significantly during the past few decades. The county is leading the state in terms of conservation accomplishments having achieved a 26 percent reduction between 2000 and 2010. The district and its municipal partners are committed to continued conservation efforts and incorporating new technology to better use and preserve our water resources.
