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.
