• Aging infrastructure
• Affordability
Pure Water Silicon Valley (PWSV) Project Overview
• Collaboration with the Cities of San José and Santa
Clara by receiving treated wastewater
• Adjacent to the existing SVAWPC
• Full Scale Facility - Capable of producing up to 24,000 Acre feet per year by 2035
• Implemented in two Projects:
• Demonstration Facility Project
o Pilot Facility (2025-2028)
o Learning Center (2025-2030)
• Full Scale Facility Project (2028-2035)
Direct Potable Reuse Facility

Water Supply Outreach
Our Goals:
• To educate
• To be transparent
• To raise awareness
• To build public support for Potable Reuse
October 13 Recommendation
▪ Support the development of needed agreements to
implement the full-scale PWSV project
▪ Support for coordinated public education and outreach programs to ensure the success of a Direct Potable Reuse project.
▪ Support project updates twice a year or as needed to
JRWPAC – next meeting scheduled for 10/29/26 focused on grants and outreach, including polling
