Purified Water Project
About the Project
Valley Water must meet future water demand and identify a sustainable water supply to combat the effects of future droughts and climate change. A Potable Reuse Project will help reach those water supply goals, which include meeting at least ten percent of water demand in Santa Clara County through recycled and purified water. This project is envisioned to be a Direct Potable Reuse project located in San José and will allow Valley Water to develop the use of purified water to supplement existing drinking water sources in a manner that minimizes environmental impacts and protects public health.
The Valley Water Board of Directors has directed staff to develop a potable reuse project with the cities of San José and Santa Clara who own and operate the San José -Santa Clara Regional Wastewater Facility, the largest in the county.
What is Purified Water? How is it different from recycled water?
Water has always been nature’s renewable resource. Purifying and recycling water simply speeds up that natural process. Recycled water generally refers to municipal wastewater that has been cleaned and meets requirements for industrial and irrigation use. Purified water is highly treated municipal wastewater that has gone through additional advanced treatment and disinfection to meet and exceed state and federal drinking water standards.
How Safe is Purified Water?
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 use purified water to add to our groundwater replenishment efforts. Valley Water will join many other places in the United States and worldwide in using this water purification and replenishment method, including Monterey and Orange counties in California, Texas, Australia, and Singapore. 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 Silicon Valley Advanced Water Purification Center.

SANTA CLARA COUNTY MEDICAL ASSOCIATION ENDORSES VALLEY WATER’S PURIFIED WATER PROJECT
Share on Facebook Share on Twitter Share on Linkedin Email this link
Following a series of presentations and discussions with representatives from Valley Water, the Santa Clara County Medical Association (SCCMA) endorsed the Purified Water Project as a safe and healthy option to add to our water supply. According to the SCCMA Committee on Environmental Health, “based on its extensive regulation and treatment, recycled [purified water] is safe for human consumption.”

CEQA Public Review (Spring 2021)
In addition to the scoping meeting, Valley Water is welcoming public comment on the scope of environmental analysis in the Environmental Impact Report (EIR). Brief details about the proposed project's purpose and objectives, an alternative to the proposed project, potential environmental impacts, and the resulting need for the EIR will be found in the project's Notice of Preparation (NOP). The NOP is posted and available for review at Valley Water's "Public Review Documents" site.
Responsible and trustee agencies, and other interested agencies, organizations, and individuals, are invited to provide written comments on the scope and content of the Draft EIR. Comments must be sent at the earliest possible date, but no later than 5 p.m. on Tuesday, April 27, 2021. Please include a name and contact information alongside your formal comments to:
