Project Update
The Draft Environmental Impact Report (DEIR) for the proposed San Antonio Backup Pipeline Project is expected to be completed by the end of 2010. The Project Design is expected to be complete in July, 2011 with construction expected to begin in winter 2012.

Project Description
The proposed San Antonio Backup Pipeline project would consist of 6,900 feet (or 1.3 miles) of 66-inch-diameter (or 5 ½ foot) steel pipe extending from the Alameda Siphons to the south to the SMP-24 Quarry, near the intersection of Calaveras Road and San Antonio Creek . The alignment of the Backup Pipeline is parallel to that of the existing San Antonio Pipeline. The project also includes new chemical storage, feed and water quality monitoring facilities for any discharges.

Currently water between the San Antonio Reservoir, the Hetch Hetchy Pipelines, and the Sunol Valley Water Treatment Plant to the south, where it is treated before delivery to customers, can move in one direction at a time through the San Antonio Pipeline. The SFPUC cannot discharge water into San Antonio from Hetch Hetchy supplies and discharge from the reservoir to the treatment plant at the same time.

Upon completion, the proposed San Antonio Backup Pipeline will enable the SFPUC to discharge Hetch Hetchy water that does not meet water quality standards and still treat San Antonio Reservoir Water at the Sunol Valley Water Treatment Plant to help provide 160 million gallons of water per day to our customers after an earthquake or major emergency.
