The Quail Creek Water Treatment Plant
Quail Creek Water Treatment Plant is an integral component of the district’s water system. The plant is capable of treating 60 million gallons of water per day — providing a safe, reliable water supply for Washington County’s growing population and economy.
The plant receives water from three sources: Quail Creek Reservoir, Sand Hollow Reservoir and the Virgin River. The water enters the facility through 60-inch pipelines capable of pumping 1,000 gallons per second and travels through numerous filters, purification elements and disinfectants during a four-hour treatment process. Certified lab technicians test water quality multiple times daily to ensure it meets or exceeds federally-regulated safe drinking water standards.
Summary of major milestones completed to date
During its 20-plus years of use, the plant has undergone a series of expansions to meet increased water demand, improve efficiencies and benefit from new technologies.
