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 were completed in FY22.
The Snell Pipeline line valve was advertised for construction in FY23.
In FY24 Q1 (July 1, 2023 – September 30, 2023), the Snell Pipeline line valve was awarded for construction, and construction activities commenced.
Construction of the remaining line valves is scheduled between FY24 and FY28, in conjunction with the 10-Year Pipeline Inspection and Rehabilitation Program. The construction of the Snell Pipeline valve will be followed by two valves along West Pipeline, and the final valve along East Pipeline.
No current documents.
