8.5 million gallon Carson sewage spill caused by corroded pipe, sewer cover, report says
Five months after 8.5 million gallons of raw sewage spilled from a ruptured mainline in Carson, an independent engineer’s report has pinpointed its cause and offered practical advice for the county agency responsible. … The rupture was primarily caused, the report said, by corrosion of both a 48-inch diameter, 1960s-era concrete pipe and a sewer cover at the intersection of 212th Street and South Lynton Avenue. … Another contributing factor in the failure, the report said, was a rain event on Dec. 30.
