Aberdeen's public works director warned Monday that a portion of nearly-century-old sewer line under Route 40 is in danger of imminent collapse.
"We know it's going to fail. We just don't know when," new public works director Kyle Torster told city leaders.
Torster noted the 18-inch sewer interceptor, which runs just south of, and parallel to, Route 22, handles about 750,000 gallons daily.
"That amounts to a lot of sewage," Torster said after the meeting. "The bottom line is, there is no place for us to treat that amount of sewage [if it collapses] and there is no way for us to re-route it."
Replacing the interceptor would cost at least $100,000, he told the City Council during a work session.
The concrete pipe, which carries about a third to half of Aberdeen's total sewage, has been eaten away by hydrogen sulfide gas, Torster explained. He showed council members video of the inside of the ragged pipe, with large sections of it missing completely.
The pipe is "starting to collapse and will be pretty hard to fix," he said.
Although the city's sewer lines are interconnected, the pipe collects sewage from about half the city, mostly west of Route 40, as well as part of the north and south sides of Route 22, Torster said.
According to the map Torster showed the council members, the pipe runs from just north of the CSX train tracks across Route 40 and ends just south of the Amtrak tracks.
