Santa Clara Valley Water District staff will tell the board Tuesday that the county's long-range water supply plan needs no changes this year, in the first annual check since the board adopted its Water Supply Master Plan 2050 last November.
The 22-page Monitoring and Assessment Program report goes to the board at its meeting Tuesday, Oct. 27, in the open session that starts at 1 p.m. at Valley Water headquarters, 5700 Almaden Expressway in San Jose, and on Zoom. It is listed for discussion and board feedback, not a vote.
The district's goal is to meet all of the county's water demand in normal years and at least 80% in droughts.
Where the big projects stand
- Pure Water Silicon Valley, a plant in North San Jose that would turn treated wastewater into as much as 24,000 acre-feet of drinking water a year, is in design for a demonstration facility and learning center budgeted at $100 million. The full plant is estimated at $2.45 billion. The report lists mixed public views of potable reuse among its risks.
- Delta Conveyance Project: Valley Water holds a 3.23% stake in the state tunnel, worth about 14,000 acre-feet a year on average, with a share of about $670 million. Staff call it on track but say regulatory changes and the lack of an approved funding method could delay it.
- B.F. Sisk Dam raise at San Luis Reservoir: the district has the largest share among participants, at a cost of $414 million to $512 million.
- Refinery Recycled Water Exchange, which would have traded recycled water to two Contra Costa refineries for federal supply, is not being actively pursued after stalling since 2023.
- A local seawater desalination feasibility study is due in early 2027.
The report also notes the Anderson Dam seismic retrofit construction contract, awarded in July for $1.88 billion, with total project cost expected near $2.8 billion.
