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
Planning and design commenced December 2019.
The 100% design documents for the line valve on Snell Pipeline have been completed. The 60% design documents for the line valves on the West Pipeline have been completed.
The following design review meetings were held:
- January 27, 2021 – West Pipeline at Santa Clara Distributary 60% design review
- January 28, 2021 – Snell Pipeline 90% design review
- March 3, 2021 – West Pipeline between Rainbow and Mann 60% design review
