Water Utility Infrastructure Master Plan Implementation Projects
The Valley Water Board of Directors approved three new projects to define long-term needs and ensure the reliability of Valley Water's water utility infrastructure.
Water Treatment Plant Master Plan Implementation Project
This project (No. 93044001) will develop a comprehensive 30-year implementation plan to identify projects to repair, replace, and/or upgrade the infrastructure at our four water treatment plants; address increasingly stringent water quality regulations; and integrate with the recently completed Water Supply Master Plan (WSMP).
Supervisory Control and Data Acquisition (SCADA) Master Plan Implementation Project
This project (No. 95044002) will prepare an update to the process control systems/SCADA master plan (2011), produce design and implementation standards for new projects, and recommend a coordinated suite of improvement projects (15-year implementation plan).
Distribution System Master Plan Implementation Project
This project (No. 95044001) will develop a comprehensive 30-year implementation plan to identify improvements to Valley Water’s raw and treated water systems based on current demands and future growth. The project will optimize our raw and treated water distribution systems, evaluate retailer needs, and recommend direct capital actions needed to protect existing distribution systems.
March 20, 2025 Notice of Preparation (NOP) and Scoping Meeting
On March 20, 2025, Valley Water held a scoping meeting on the Water Treatment Plant Master Plan Implementation Project Program Environmental Impact Report Notice of Preparation. The hybrid event took place in the Valley Water Headquarters Board Room and was offered through Zoom. Vice Chair Santos provided opening remarks to the seven public participants who joined online, which included Directors Nai Hsueh and Rebecca Eisenberg.
The presentation included a project overview and information on how to submit formal comments. It was followed by a Question-and-Answer session, where staff engaged with community members.
Valley Water, as the lead agency under the California Environmental Quality Act (CEQA), has published the NOP, which is available online (http://www.valleywater.org/public-review-documents) for a 30-day public review period.

June 13, 2024 Water Treatment Plant Master Plan Public Meeting
During this public meeting at the Vietnamese American Service Center, Valley Water presented a comprehensive and long-term plan to update and upgrade its water treatment plants. Several potential projects have been identified for each plant in the plan. The presentation addresses the need for and importance of having a Master Plan and an open forum for questions.

The status of each of the implementation projects is provided below as of August 7, 2026.
Water Treatment Plant Master Plan Implementation Project:
Staff completed the Project Development, Evaluation, and Planning Study Report and the Project Implementation Plan, including the Basis of Design Reports and Technical Baseline Document. These deliverables establish the recommended long-term capital improvements and implementation strategy for Valley Water's water treatment facilities and provide the technical basis for future capital project development.
Staff continues to advance environmental planning by developing the Programmatic Environmental Impact Report (PEIR) and supporting implementation-focused supplemental studies, including the Silicon Valley Advanced Water Purification Center and Liquid Ammonium Sulfate (LAS) projects. Current efforts include advancing LAS 10% design development and preparing the Public Draft PEIR for release.
SCADA Master Plan Implementation Project:
SCADA platform selection activities are ongoing. Staff is currently reviewing a qualitative evaluation of ten solutions based on design considerations, including system architecture and programming environment; performance considerations, including cybersecurity and alarm management; and support considerations, including revision control and lifecycle cost.
Staff is also developing standardized testing scenarios for on-site demonstrations by up to four shortlisted vendors later this year.
Distribution System Master Plan Implementation Project:
Staff completed the Pump Station Evaluation Technical Memorandum (TM), documenting condition assessments, estimated remaining useful life, and renewal recommendations for the Pacheco, Coyote, Intertie, and Wolfe Road pump stations, as well as the Campbell Well Field and San Tomas Injection Well facilities. These evaluations provide the technical foundation for future capital planning and long-term asset management.
Staff is also advancing the evaluation of Valley Water's inactive canals and recycled water facilities. Recent work includes preparing a draft evaluation memorandum for a recycled water pipeline and continued refinement of GIS-based condition and consequence-of-failure information. Concurrently, staff is developing the Problem Definition Report, which organizes and prioritizes system needs and potential capital improvement projects to support the development of the long-term capital program.
