SAN DIEGO (CNS) – A ruptured water line in an alley flooded a section of South Mission Beach Wednesday afternoon.

The broken pipeline began inundating the access road off the 2700 block of Bayside Lane about 4 p.m., according to San Diego police.

The overflow submerged parts of nearby Mission Boulevard along with adjacent sidewalks and parts of other alleys. No structural flooding was immediately reported.

Mission Beach resident Tony Serafin said a service truck drove through the water break and sunk.

“When I first saw it, the vehicle already was in the hole,” Serafin said, “and the water was still percolating up and the front end of the service van or vehicle was in the hole.”

He added that the hole is concerning, but he knows city crews have been working along Mission Boulevard.

“They’re working on servicing the pipes down here and stuff,” he said. “It’s in progress. I know it takes time. They’ve serviced North Mission and they’re working their way down.”

Utility crews had the overflow under control by late afternoon, city spokesman Arian Collins said.

“Crews have not yet determined the number of customers affected, and the cause of the break is not yet known,” Collins said shortly before 6:30 p.m.

As of about 10:15 p.m., the city issued a precautionary boil water notice for about 25 homes in the 2700 block of Bayside Lane.

“Staff from the Public Utilities Dept. will directly notify customers impacted by the boil water notice,” the city said in a tweet.

Repair personnel expected to have repairs to the pipeline completed and water service fully restored to the neighborhood by 2 a.m. Thursday.
