The 12-inch pipe burst around 8:10 a.m. on Story Road at Lyndale Avenue, spokesman John Tang said.
Service was shut off, affecting 25 residents on Story Road between Lyndale Avenue and Stonehedge Way, according to a San Jose Water customer service representative.
Water service is expected to be restored by late this afternoon. "We expect minimal impact," Tang said. "We are not seeing any damage from any flooding."
There is water in the area and crews are working quickly to repair the leak, he said.
A woman answering the phone at the San Jose Foothill Family Community Clinic, located at 2880 Story Road, said around 9 a.m. that the water was spewing from the middle of the road near the Safeway on Story Road.
She said she hadn't seen any flooding and that it's "not to the point where it's scary."
The water main break is one of a handful throughout the city today.
A water company customer service representative said four other smaller breaks were also reported this morning, including at Woodhaven and Dale drives and Alum Rock Avenue and Edgemont Drive.
