As Hyperion sewage spill worsened, communications failed
Multiple failures in communication between Los Angeles city and county agencies delayed crucial public warnings and a full emergency response to a massive sewage discharge earlier this month at the Hyperion Water Reclamation Plant, according to a report obtained by The Times that was discussed Tuesday by county officials. The report provides new details regarding plant flooding and the evacuation of staff just before an hours-long discharge of 17 million gallons of raw sewage into the waters off Dockweiler and El Segundo beaches July 11 and 12.
