8:40 p.m.A Napa city water main broke in west Napa Thursday afternoon at about 5 p.m., disrupting service for residential customers and causing minor damage to two apartments.

The break happened on the 2500 block of Laurel Street, near where Laurel meets Kilburn Avenue and Freeway Drive. Laurel was closed between Freeway Drive and Avon Street while crews worked to repair the damage.

Napa Fire Department Public Information Officer Patrick Young said that a 12-inch water main broke in front of the large apartment complexes on Laurel, knocking out service to about 500 residents, bringing about one inch of water into two apartments and causing water pressure to drop around the neighborhood.

No one was hurt as a result of the break.

The water that erupted into the street was brown, which Young attributed to sediment in the line that had been stirred up when the main broke. He said the water contained no sewage.

As of 8 p.m. Young estimated it would take until midnight to make the repairs and fully restore service.

City workers knocked on doors in the apartment complex Friday evening, warning people not to use the water for drinking at least until morning.
