Examples of Successful Projects
Silicon Valley Advanced Water Purification Center
Santa Clara Valley Water District, California
The Silicon Valley Advanced Water Purification Center, the largest plant of its kind in northern California, is the focal point of the Santa Clara Valley Water District’s recycled water expansion.
The $72 million state-of-the-art facility receives secondary-treated effluent from the neighboring San José-Santa Clara Regional Wastewater Facility and purifies it to a very high quality using proven purification processes—microfiltration, reverse osmosis and ultraviolet disinfection.
The result is eight million gallons a day of highly purified water that is expected to match California drinking water quality standards. The highly purified water produced at the purification center is blended with the recycled water supply produced at the regional wastewater facility to enhance its quality and expand its usage via the South Bay Water Recycling system.
Orange County Water District, California
The Groundwater Replenishment System (GWRS) is the world’s largest water purification system for indirect potable reuse. Operational since January 2008, the GWRS is a state-of-the-art water purification project that can produce up to 100 million gallons (379,000 cubic meters) of high-quality water every day. The system takes highly treated wastewater that would have previously been discharged into the Pacific Ocean and purifies it using a three-step advanced treatment process consisting of microfiltration, reverse osmosis and ultraviolet light with hydrogen peroxide.
- Decreases Southern California’s dependency on imported water from the Sacramento-San Joaquin River Delta and the Colorado River.
- Creates a locally-controlled, reliable supply of high-quality water that is drought-resilient.
- Provides Orange County communities added assurance of sufficient water supplies to support economic vitality.
- Produces high-quality water to replenish the groundwater basin.
- Protects Orange County’s groundwater basin from seawater intrusion.
- Serves as a blueprint for water agencies throughout the world to help solve their local water supply issues.
- Protects the environment by reusing a precious resource.
- Reduces the amount of wastewater discharged to the Pacific Ocean.
Hampton Roads Sanitation District (SWIFT)
SWIFT is an innovative water treatment project in eastern Virginia designed to further protect the region’s environment, enhance the sustainability of the region’s long-term groundwater supply and help address environmental pressures such as Chesapeake Bay restoration, sea level rise and saltwater intrusion. SWIFT’s Advanced Water Treatment Process produces drinking water quality SWIFT Water through a multi-step disinfection process that is used throughout the country and the world.
