In April 2015, the Regional Groundwater Storage and Recovery project kicked off construction at the Linear Park site in South San Francisco. Only one year later, the project is more than 32 percent complete and overcoming construction challenges to reach the finish line.
Workers install steel rebar to prepare for the wall pours at the Linear Park well station in July 2015. On the right is the completed exterior of the Linear Park well station in March 2016.
In November 2015, the project started well drilling activities at the Treasure Island site in South San Francisco. The project completed drilling all wells apart of this contract in early 2016.
Construction crews finished installing new pipeline on South Spruce Avenue in South San Francisco in March 2016.
With these milestones successfully complete, the project team knows there is still a lot of work to be done before completion in October 2017.
Thank you for being wonderful customers and neighbors throughout construction in 2015. It has been a busy year on the Peninsula, the SFPUC’s Water System Improvement Program (WSIP) celebrated the completion of the Harry Tracy Water Treatment Plant in San Bruno and the last major water transmission pipeline in the Peninsula region coming into service.
While the Water System Improvement Program overall is now 90 percent complete, we still have a long way to go and our crews are hard at work this holiday season. Below are the construction schedules for the Peninsula Pipeline Seismic Upgrade, Regional Groundwater Storage & Recovery Projects and the San Andreas Pipeline #2 at Junipero Serra Park.
Construction will be suspended Thursday, December 24 through Sunday, December 27.
Construction will be suspended Thursday, December 31 through Sunday, January 3.
Regular construction schedules will resume Monday, January 4.
The Regional Groundwater Storage & Recovery (GSR) Project has multiple active sites across five cities: Daly City, South San Francisco, Millbrae, Colma and San Bruno. In an effort to keep you informed about construction activities, detours and other project updates associated with GSR Project’s 13 sites, we have developed a Geographic Information System (GIS) Map. This GIS map will be located on the project webpage www.sfwater.org/GSR. The map will be updated regularly depending on construction activities. A a snapshot of the GIS map with functionality capabilities is below.

The Peninsula Pipelines Seismic Upgrade (PPSU) is starting construction! The construction contract was awarded to Ranger Pipelines, Inc. Pre-construction work is already underway with construction activities scheduled to begin in August 2014. The PPSU project consists of seismic upgrades to three critical water delivery pipelines in Northern San Mateo County. These upgrades are needed to ensure drinking water delivery to our customers following an earthquake. We will replace segments of the pipeline, open-trench construction, surface restoration and installing structural support within an existing tunnel. The PPSU project spans six improvement components in four different cities on the San Francisco Peninsula within San Mateo County: Millbrae, South San Francisco, San Bruno and Colma. For more details, view the project fact sheet here. This pipeline project is one of more than 80 water improvement projects that are part of the Hetch Hetchy Water System Improvement Program (WSIP). The PPSU project is the final pipeline replacement project in the WSIP program. To kick off construction, the PPSU project team will host an open house event on Thursday, July 24 at the City of Millbrae Public Library (1 Library Avenue, Millbrae, CA, 94030). The public is invited to talk with the project team about upcoming construction activities between 5:30 p.m. and 7:30 p.m. To receive project updates, please subscribe to this blog or visit our project web page www.sfwater.org/PPSU.
