Westside Potable Emergency Firefighting Water System

The San Francisco Public Utilities Commission (SFPUC) is proposing construction of the Westside Potable Emergency Firefighting Water System project (project), which would add a dual-purpose, earthquake-resistant high-pressure water transmission pipeline within existing public streets to provide both fire protection and redundancy for potable water conveyance to western San Francisco. The project would include installation of approximately 16 miles of belowground pipeline and associated appurtenances. In addition, improvements would be installed at existing SFPUC facilities as follows: 1) pump station upgrades at the Lake Merced Pump Station; and 2) two new emergency pump stations at the existing Central Pump Station/Merced Manor Reservoir and at Sunset Reservoir. The project would be designed and constructed in phases as funding becomes available, with construction over approximately 15 years from 2026 through 2040. The project would extend generally from Lake Merced in the south to Lincoln Park and the Presidio in the north, generally bounded by Park Presidio Boulevard and 19th Avenue on the east and the Great Highway on the west.
