Document Description
The San Francisco Public Utilities Commission (SFPUC) proposes to implement the San Antonio Backup Pipeline (SABPL) project to provide reliable conveyance capacity for planned and emergency discharges of Hetch Hetchy water out of the SFPUC regional water system under future flow conditions. The proposed improvements include a 7,000-foot-long backup pipeline, discharge facility, cutoff wall, dewatering facilities, pump station and wet well, and new conveyance pipelines. The proposed improvements would allow the SFPUC to discharge the full maximum future flow to a quarry pit, and subsequently conserve the discharged water by pumping the water to either San Antonio Reservoir for storage or to the Sunol Valley Water Treatment Plant for treatment and subsequent delivery to customers. The proposed project would also increase operational flexibility and delivery reliability during emergencies and planned maintenance activities, thereby minimizing the risk of water supply service interruption. The proposed project has a 21-month construction schedule, from approximately October 2012 through June 2014. All project components would be located in the Sunol Valley on Alameda watershed lands owned by the City and County of San Francisco (CCSF) and managed by the SFPUC.
