Water main break reported in Mission Terrace neighborhood

Utility crews are working to shut off water following a water main break this morning in San Francisco’s Mission Terrace neighborhood, a
spokeswoman for the city’s public utilities commission said.

As of at 10:10 a.m., there had been only one report of flooding, at a building on Onondaga Avenue, near Alemany Boulevard, San Francisco Public Utilities Commission spokeswoman Alison Kastama said.

The 8-inch water main line is in the process of being shut off, Kastama said.

While crews make repairs, the SFPUC is shutting off water to buildings on Onondaga Avenue between Mission Street and Alemany Boulevard, as well as on Alemany Boulevard between Onondaga Avenue and Ocean Avenue, according to Kastama.

Repairs are expected to take between four and six hours, she said.

Kastama said the ruptured water main line is located about 3 to 4 feet beneath the ground. While the cause of the break has not been determined, she said ruptures are most commonly a result of age.

She said some of the 1,200 miles of water mains beneath the city date back to 1895.

Kastama said the age of the main that ruptured today hasn’t been determined.Mission TerraceSFPUCwater main break
