What is purified water?

Water has always been nature’s renewable resource and is constantly moving through the water cycle. Purifying water simply speeds up that natural process by using a multistep effort to remove potential water contaminants, creating a drought-resilient and sustainable water source. Purified water first starts out as highly treated wastewater that has already gone through a multi-step treatment process at a wastewater facility. Once that highly treated wastewater arrives at the Silicon Valley Advance Water Purification Center, it goes through a multi-step purification process, which can include micro-filtration, reverse osmosis, UV light disinfection, and advanced oxidation. This purified water is treated to strict standards set by the Division of Drinking Water and is rigorously monitored by local, state, and federal agencies to ensure it continuously meets those standards. All purified water in Santa Clara County meets or exceeds standards set by the state.

How Safe is Purified Water?
As mentioned, purified water is safe and meets or exceeds state and federal drinking water standards. It is tested regularly by our certified Water Quality Lab to ensure safety and quality. Upon completion of the Purified Water Project, Valley Water will be able to expand its drinking water supply by integrating purified water with Santa Clara County’s existing drinking water resources. Valley Water will join many other places in the United States and worldwide in using this advanced water purification process including Monterey and Orange counties in California, Big Spring and El Paso in Texas, Australia, and Singapore.

The Silicon Valley Advanced Water Purification Center (SVAWPC) and the Purified Water Project
To learn more about how purified water is used as a drinking water source and the purification treatment process, please visit purewater4u.org. There, you can also sign up for tours of the existing SVAWPC, which currently produces up to eight million gallons per day of highly purified water.

This highly purified water is blended into existing recycled water provided by SBWR, which improves overall recycled water quality so that the water can be used for a wider variety of irrigation and industrial purposes.
