Last week, you probably noticed some construction and tree maintenance along Haight Street between Divisadero and Pierce. Both are connected to an ongoing major sewer infrastructure project along Haight and Hayes streets.

The Department of Public Works is replacing the Haight Street sewer line in sections. They recently finished construction between Masonic and Central, and last week they began work in the Lower Haight by sawing off part of the sewer trench.

Yesterday, contractors started excavating down the middle of the street so they can install a 12-inch-wide sewer line. After four or five weeks of this, they'll replace the sewer laterals (the connection between the main sewer line and sidewalk).

“Typically, the sequence of work includes installation of the new sewer main, review of a video by the city to determine which laterals, if any, need to be replaced, then the contractor returns to replace laterals per direction of the City,” said Alex Murillo of the DPW.

Expect construction in this area every weekday for the next few weeks. Because the sewer line goes down the middle of the street, traffic must be pushed toward the curb. This, of course, means no parking on this section of Haight during construction.
