Penitencia Delivery Main and Penitencia Force Main Seismic Retrofit Project

 

About the project

The Penitencia Delivery Main and Penitencia Force Main Seismic Retrofit Project (download project fact sheet) is located within the Santa Clara Valley Water District’s  Penitencia Water Treatment Plan in the City of San Jose.

The Project limits are bounded by Piedmont Road to the west and the Penitencia Water Treatment Plant to the east. The pipeline replacement work is located within the water district’s right-of-way between Grossmont Drive in the west to just west of Vista del Mar.

The Project entails replacement of about 835 feet each of the Penitencia Delivery Main (PDM), Penitencia Force Main (PFM), and the South Bay Aqueduct (SBA). The Penitencia Force Main and the South Bay Aqueduct deliver raw (untreated) water to the Penitencia Water Treatment Plant and these pipes range in size between 5.5 feet and 6 feet in diameter.

The Penitencia Delivery Main delivers treated water to our water retailers such as the San Jose Water Company. The water retailers then distribute water to the residents. The objective of this Project is to replace the existing concrete pipe with new pipelines that will be able to accommodate the gradual creeping ground movement from the active Penitencia Creek Landslide and potentially extensive ground movement from a major seismic event.

In its current condition, the PDM, PFM, and SBA pipelines are vulnerable to pipeline failure from a large earthquake. This Project is necessary to reduce time and costs associated with pipeline restoration, lost revenue, and potential damage to nearby residential and public school property due to a large earthquake. At the completion of the Project improvements, the water district will continue to monitor and maintain the pipelines.

The latest

The project team analyzed a range of alternatives and selected the staff-recommended alternative. The Planning Study Report was completed in November 2014.

The design phase began in September 2014 and was completed by March 2016. On March 22, the water district Board of Directors awarded the construction contract to Ranger Pipelines, Inc. in the amount of $21.5 million.

Environmental Document
In accordance with the California Environmental Quality Act, the water district prepared an Initial Study/Mitigated Negative Declaration (IS/MND) for this Project. The draft IS/MND was circulated for public review between June 22 through July 21, 2015. On September 22, 2015, the water district Board of Directors approved a resolution adopting the Final IS/MND for this Project.
