If you drive from Precita up to Bernal Hill on Alabama, you'll see a lot of construction. It's the "Bernal Heights Pipeline", which is being replaced by digging a tunnel under Bernal. Tikirobot has some good pictures and more information about this.

Construction Update: Affholder Construction, the tunneling contractor continues boring work within City property through Bernal Hill. The closure of Powhattan Street between Nevada & Nebraska (the "tunnel head") continues until October. Work continues at Cortland Avenue and Nebraska Streets. Some parking has been temporarily removed at Alabama & Ripley and traffic patterns have slightly changed. The storing of some materials and equipment is located at Powhattan & Nebraska and also at Bernal Heights Boulevard near Bradford Street.

The target completion date for this project is October 2007.

Work has now started at Ripley and Alabama, another "tunnel head". Apparently, the tunnel goes directly under some homes. The old tunnel went directly under some homes, but the new tunnel is trying to avoid going under homes. (This is what I've been told, but don't have a reference to back it up.)

Here's a map of the San Francisco water system. You can see this main on the upper left side of SF.
