About eight to 10 homes in Los Altos will be without water Sunday night and Monday morning as crews work to repair a water main break in the city, police said.
The break was first reported at 7:11 p.m. at Rosita Avenue and Springer Road.
Utility crews with California Water Service have shut off the water but repairs won't start until a PG&E crew marks the area so digging can begin, Los Altos police Agent Mark Thomsen said.
No homes have been flooded and no one has been evacuated, according to Thomsen.
Eighty to 90 percent of the water is flowing into nearby Hale Creek, so it's not affecting the homes. The rest of the water is flowing down Springer Road, Thomsen said.
Rosita Avenue between Parma Way and Springer Road is closed because of the break.
Thomsen said the closure will probably not affect traffic in the morning because it can be rerouted onto nearby streets.
The cause has yet to be determined and Thomsen did not say when service might be restored.
