Washington County Water Conservancy District, Utah, USA – Planned Reservoir Augmentation

The Regional Reuse Purification System is a planned water infrastructure network comprised of reclamation facilities, advanced water purification technology, conveyance and storage facilities to optimise the use of all existing water supplies and create new local water resources for the communities of Washington County, Utah.

The system will extend the region’s reusable supply, making it available to residents, businesses and farms. With a focus on improving resilience, the system is a key pillar of One Water Washington County, which aims to make the most efficient use of all water throughout the region.

Washington County is one of the fastest growing regions in the United States and is dependent on one limited water source – the Virgin River Basin. The region’s drinking water supply comes from a combination of surface and groundwater sources in this basin. Reuse has been used for irrigation since 2006.

The system will serve approximately 350,000 full-time residents by the 2040s as well as a high number of seasonal populations and visitors, which increase resident population by almost 40 per cent. By 2045, approximately 28 per cent of water demand will be met with purified recycled water.

An advanced water purification demonstration facility is currently in the planning phase with an anticipated completion date of 2028. The facility is anticipated to produce 200 gpm of water that meets or exceeds drinking water standards.
