The smoke testing of the city’s sewer lines Nov. 18 through 22 was successful. Crews found several problem spots, Paine said.

“Most problems were residential cleanouts, but there are a few places that need to be repaired,” he said.

The testing showed city crews where water was getting into the sewer lines.

“It’s causing some overflow issues at the plant,” Paine said. “There should not be that much water in those lines.”

The city will send out letters to residents with problems.

“We had a few things we need to look at,” he said.

One problem crews will address immediately is a storm sewer catch where smoke was escaping on Birch St. Paine said a couple of fire calls were attributed to the testing.
