College Hill Reservoir Outlet & Pipeline Project

Overview

The San Francisco Public Utilities Commission (SFPUC) and its contractor (Ranger Pipelines) is replacing a portion of an existing large diameter water transmission pipeline (College Hill Pipeline) which runs from the College Hill Reservoir; through SFPUC’s Right of Way and across the unpaved portion of Prospect Avenue to Cortland Avenue.  Additional new pipeline connections will also be made on Santa Marina Street from Prospect to Mission Street with an upgrade to the fire hydrant connection on Gladys Street at Santa Marina. The project also includes the installation of new reservoir roof vaults, improved road access (within the reservoir) and electrical upgrades. 

Current work on this project is taking place within the Reservoir grounds and on the right-of-way leading to Santa Marina Street. This includes construction of a vault to house valves for seismically resistant water mains.

Drivers should exercise caution as construction vehicles will utilize entrances on both on Appleton Avenue and Elsie Street during working hours. See shaded areas on map below.
