San Diego

Ten thousand gallons of sewage spilled into the south end of San Diego Bay on Wednesday night and Thursday morning after a power outage at a pump station caused a backup, a county Department of Health Services spokesman said.

Pumps at the station stopped moving the sewage when the outage occurred, department spokesman Dan Avera said. The backup sent sewage into the bay just north of the pump station, at Silver Strand State Beach and Coronado Cays Park.

The spill began at about 10 p.m. Wednesday and lasted 5 1/2 hours.

It was the second sewage spill of the day, Avera said.


Earlier Wednesday, a sewer main blocked by tree roots forced 2,700 gallons of sewage through a manhole at 760 Dodge Drive and into a storm drain, Avera said.

The waste emptied into the ocean in the 5900 block of Camino de la Costa, just north of La Jolla Hermosa Park. The roots were removed within 90 minutes, Avera said.

Signs were posted at both sites because of potential health problems, Avera said.
