Crystal Springs Pipeline No. 2 (CSPL) extends from a point near the Crystal Springs Pump Station CSPS in unincorporated San Mateo County to the University Mound Reservoir in San Francisco. The pipeline is primarily 60-inch-diameter pipe with a 3.2 mile section that is 54-inch-diameter pipe. The purpose of the project is to improve seismic reliability of the pipeline. The project is provided in response to the Seismic Reliability level of service goals

Description
The proposed major project elements consist of:

• Seismic reliability improvements, which would include replacing or relocating a total of 1.7 miles of pipe at 12 locations, sliplining, which removes obstructions such as roots, large joint offsets, rocks or other debris, 3.5 miles of pipe, replacing pipe bridge pier supports at two creek crossings, providing a new connection at the (CSPS), and providing a connecting segment with a blind flange for later connection to the New Crystal Springs Bypass Tunnel.  The tie-in to the New Crystal Springs Bypass Tunnel would be performed under project CUW-35601 (Lower Crystal Springs Dam Improvements), eliminating the need for a second shutdown of the CSPL No. 2.
• Installation of a new isolation valve at the CSPS.
• Facility improvements, which would include installing fences and enclosures for exposed facilities, concealing exposed portions of pipe, and painting exposed portions of pipe.
• Upgrading the cathodic protection system along the length of the pipeline.
