Sinkhole forms in SF after water main break

2 mins read

A water main break in the area of Fillmore and Green streets in San Francisco’s Cow Hollow neighborhood has led to a sinkhole forming in an intersection, the San Francisco Public Utilities Commission confirms. 

PG&E was on the scene attempting to isolate a gas main and once that is complete, crews will continue to work on the water mains. 

The sinkhole formed at the intersection of Union and Green at around 11 a.m. on Monday. 

The sinkhole has disrupted bus service and Muni is replacing trolley buses with motor coaches. 

District 2 Supervisor Catherine Stefani says city staff are at the location and conducting outreach to businesses and homes impacted by the water main break. 

PG&E and SF Fire are monitoring a gas line in the area. 

The water main, which was installed in 1949, according to the San Francisco Public Utilities Commission, broke shortly before midnight on Sunday. The break in the 16-inch water main also affected a nearby 8-inch main at Fillmore and Union Street, according to SFPUC. The 8-inch man has been repaired and normal water service has been restored as of 2:25 p.m., according to SFPUC.

“Customers in the surrounding area are experiencing intermittent water service and temporary service interruption,” SFPUC said. “Our crews are working to restore water service as soon as possible.”

Crews remain in the area and work on the main and sinkhole is ongoing.
