San Onofre treatment plant problem leads to release of 7,000 gallons of partially treated sewage into ocean
In an alert to state regulators, Southern California Edison, which operates the power station, said an unexpected surge of wastewater led to an “upset” at the treatment plant that morning, triggering an alarm but allowing the sewage to flow through a 6,000-foot pipe out into the ocean before workers could turn off the pumps.
