Crews are working to repair a concrete water main break on the 4600 block of Morena Boulevard.
The 12-inch diameter main broke early Saturday morning, the City of San Diego Public Utilities Department said.
As a result, about 10 customers on the 4400 block of Morena Boulevard do not have water. Water service should be restored by 8 p.m.
A water wagon is on site for those without water to provide water for their drinking, cooking and other needs.
No further information was immediately available.
