Project Description

SFPUC contractor Ranger Pipelines Inc. has replaced or repaired segments of a 19-mile pipeline known as Crystal Springs Pipeline No. 2. The work areas included intermittent sites along El Camino Real between Hillsborough, Burlingame and Millbrae. Other segments of work occurred in unincorporated sections of San Mateo County, Hillsborough, South San Francisco, San Bruno, Brisbane and Daly City.

The goal of this project was to ensure that our region’s water system infrastructure has a sustainable and reliable water supply. This pipeline was one of many water facilities in the region that had been identified for repair under the WSIP. Crystal Springs Pipeline No. 2 was installed between 1900 and 1930, and is one of the oldest and most critical water mains in the regional water system.

Some of the benefits of this project include:

  • Relocating sections of the pipeline to avoid unstable surface area surrounding the pipe
  • Retrofitting pipe bridge supports at two locations to withstand seismic events
  • Inserting new sections of pipes into existing pipeline to strengthen the pipe wall
  • Refining the water system to minimize the potential for corrosion of the pipeline
  • Replacing sections of the pipeline with thicker welded steel pipe
