Washington County’s 2022 consumptive use was 153 gallons per capita per day (GPCD). This figure represents the total water consumed divided by the total population divided by 365 days, as set forth in Utah State Statue.
To meet the projected demands of Washington County’s growing population through 2042, the district will pursue a combination of initiatives, as outlined in its 20-year water supply plan. The plan will provide 46,615 acre feet of water at a cost of more than $1 billion through the following efforts:
Water Conservation: extend available supply primarily through lawn replacement incentives, reducing system loss, improving rate structures and installing smart meters
Regional Reuse System: construct new reuse water infrastructure for agricultural and irrigation purposes, including reservoirs, pipelines and water treatment facilities, to free up potable water
Potable Water Development Projects: develop new reservoirs and expand well systems to augment local potable water supplies and available storage facilities
Municipal Groundwater Optimization: conduct hydrologic studies of groundwater accessibility and reliability to identify availability and safe yields of local aquifer storage
Agricultural Conversion: transition available agricultural water to municipal development
The district is planning water resources decades in advance because Washington County is one of the fastest-growing regions in the nation and water projects take decades to permit and build.
To conserve potable water supplies for Washington County’s rapidly growing population and economy, reuse and secondary (untreated) water is used to irrigate parks, golf courses, schools, churches, cemeteries and other landscapes.
