Vandalism is suspected to have caused a sewage spill that began Saturday morning and forced about 100,000 gallons of untreated waste from manholes into residential streets in Southeast San Diego, said Jim Phillips, a city Water Utilities Department supervisor.
The spill was stopped at 5:30 p.m. Sunday after a 1,500-foot-long snake was used to clear 321 feet of a blocked sewer line running down Elwood Avenue.
On Monday, two cleanup crews were sent to Elwood and Geneva avenues in Encanto, where the spill was first reported, to hose down the neighborhood and remove the remaining rocks and debris from the sewer line, Phillips said. The cleanup was completed Monday afternoon.
"We suspect vandalism and are going to inspect manholes leading into this area," Phillips said.
If it is determined that manhole covers were removed and rocks were put into the sewer system, the manholes will be "strapped and sealed" to render them "vandal-proof," he said.
