A 100-year-old sewer main collapsed in San Francisco’s Richmond District this morning, a utilities spokeswoman said.
The sewer main failed between 8 a.m. and 9 a.m., causing a 2-foot sinkhole on 15th Avenue between Clement Street and Geary Boulevard, San Francisco Public Utilities Commission spokeswoman Betsy Rhodes said.
No residents lost water service, Rhodes said, though crews closed the street in order to make temporary repairs.
The street should reopen later this evening, Rhodes said.
According to the SFPUC, the aging sewer line that collapsed was scheduled to be replaced this month as part of the agency’s multi-billion dollar program to upgrade the city’s sewer system.
