The Silicon Valley Advanced Water Purification Center, SVAWPC, offers free tours to the public to teach them about the advanced treatment processes and the role of recycled and purified water as a future sustainable water supply.
The award-winning facility uses advanced technologies to purify secondary treated wastewater, which is wastewater that has already been cleaned twice and is similar to river water. The plant produces clean high-quality water through microfiltration, reverse osmosis and ultraviolet light.
The result is eight million gallons a day of highly purified water that is expected to match California drinking water quality standards. NBC Bay Area sent a sample of water from the purification center to an independent lab to be tested, and it passed with flying colors!
Sign up for a free tour of the SVAWPC, the largest plant of its kind in Northern California, and a showcase of how water reuse will grow as a drought-proof, environmentally friendly water supply in the coming years. Tour registration closes when tours are fully booked and will not show on the tour registration page.
Location of the facility is 4190 Zanker Road, San Jose CA 95134.
Innovation for Future Water Supply
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.
Total dissolved solids (TDS) is a good water quality marker and it’s the key factor that non-potable recycled water users are concerned with. The highly purified water produced at the purification center has an average TDS concentration of around 40 milligrams per liter.
The addition of this purified water to recycled water reduces the recycled water TDS levels from the 2013 average of 750 ppm to the targeted 500 ppm, thus making a good product even better. This enhancement in water quality will allow for a wider use of recycled water for a variety of purposes, such as irrigation, commercial and industrial. For example, with lower TDS industrial customers would require less pre-treatment to avoid scaling, while landscape users would see reduction in leaching to remove excess salt from the soil.

The center demonstrates proven technologies to produce highly purified water that can be used for a variety of purposes, including potentially expanding Silicon Valley’s future drinking water supplies.
The water district, which is the largest funder with $47.5 million, owns and operates the facility. The City of San José has provided $11 million. The purification center has received $8.25 million from the federal American Recovery and Reinvestment Act and $5.25 million from the California Department of Water Resources.
