Snapshot of slip-lining work that recently took place on Drumm St
Sewer construction crews will be doing Saturday work at the intersection of Spear St at Mission, 8am to 8pm, Sat, February 22. Work includes potholing for utilities underground to make sure there are no conflicts before installing the sewer pipeline.
What you can expect during this work:
* Parking will be restricted throughout work zone. Please see posted signs for exact details.
* Traffic will be reduced to one lane; traffic controls will be in place, with flaggers and SFPD officers. Please allow extra time when driving in the work zone.
* A city construction inspector will be on-site during work hours and may be able to assist you with construction concerns.
* Although MUNI buses will shift slightly through the intersection to accommodate this work, the location of bus stops remain the same, so rider commutes should not be affected.
Non-SFPUC utility work on Spear Street between Mission and Market: PG&E will be doing work on Spear St between Mission and Market St from 8pm Friday, 2/21 through the weekend if needed.

Crews have removed the concrete slab, and will be continuing work for ground stabilization. Upon completion of this activity, sewer pipe installation using the “auger-boring” method will start. .
Drumm Street will remain closed between Market and Clay Streets, with two-way traffic on southbound lanes of Drumm Street. Commuters traveling to/from the area should remember:

Other SFPUC Construction Activities Nearby: Empire Engineering & Construction, contractor for the SFPUC, will begin the installation of a new 8” water main pipe on Jackson St from Stockton to Grant & Sansome to Front; Washington St from Davis to Battery; Sacramento St from Battery to Drumm (crews will replace the sewer main on Sacramento between Front & Battery); and Davis St from Sacramento to Market. This project will replace pipes in the street that are approaching the end of their useful life. While the projects are unrelated, there will be coordination between these projects to minimize impacts. For more information on the water main installation project, please see the public notice.
Construct a bypass to the existing North Shore Force Main with a redundant pipeline so that this existing pressurized sewer pipeline can be taken off line for repairs without disruption to service or sewage overflows to the Bay.
The existing force main is near the end of its useful life and has failed twice in 2008, and most recently in March 2012. Currently this pipeline transports combined wastewater to the Southeast Wastewater Treatment Plant -- serving more than 350,000 people.
The contractor, KJ Woods, will construct a new 3,300-foot-long sewer force main pipeline to divert combined wastewater away from the portion of the existing force main that is susceptible to failure, install a new underground vault and other supporting facilities. The contractor will also replace or relocate approximately 1,600 feet of water mains, and repave most of the affected streets.

Comparing the Embarcadero wharf from centuries ago with today’s built up environment, helps us understand the difficulties the design engineers and contractor constantly struggle with as they encounter unmarked piers, buried brick sewers and other remains from the 1800s.
