Last night's rain caused a power outage in the Sunset District around 8:30 p.m. that left some 5,800 PG&E customers in the dark and knocked out power to part of the city's wastewater treatment system. According to the Ocean Beach Bulletin, without power the treatment system evacuated partly treated wastewater in the waters near Lincoln Way, Vicente Street and Lake Merced. Due to the accidental sewage evacuation, the SF Public Utilities Commission has posted warnings to avoid contact with the waters along Ocean Beach and Fort Funston.

Power was restored to the PG&E Customers before 10 p.m., but no-contact warnings at Ocean Beach and Fort Funston are still in place. If anyone is hoping to get in a St. Patrick's Day surf session, check SFPUC's water quality site first for status updates.
