This project constructs four (4) line valves at various locations along the East, West and Snell treated water pipelines in Saratoga, Cupertino and San José. Once constructed, this project will allow Valley Water to isolate sections of pipelines for scheduled maintenance and repairs following a catastrophic event, such as a major earthquake, and allow the network of emergency wells to operate, even when there is damage upstream and downstream of individual wells.
Planning and Design Updates
The 100% design documents for the four line valves have been completed
The following design review meetings were held:
- July 7, 2021 – East Pipeline Design Transition
- July 13, 2021 – West Pipeline at Santa Clara Distributary Design Transition
- July 29, 2021 – West Pipeline between Rainbow and Mann 90% design review
- September 8, 2021 – West Pipeline between Rainbow and Mann Design Transition
Construction is scheduled for FY23 through FY28, in conjunction with the 10-Year Pipeline Inspection and Rehabilitation Program.
