Washington County Consumption
Washington County’s 2025 consumptive use was 145 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 Statute.
To meet the projected demands of Washington County’s growing population through 2046, the district will pursue a combination of initiatives, as outlined in its 20-year water supply outlook.
20-Year Water Supply Outlook
Water Conservation
Extend available supply primarily through lawn replacement incentives, reducing system loss, improving rate structures and installing smart meters
Regional Reuse Purification 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

Meeting Future Demand
Approximately half of the water needed to meet future demand will come from additional conservation. The other half will come from a combination of initiatives (see chart on the left) that will add about 40,000 acre feet to our water supply at a cost of approximately $ 2 billion.
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.
