PITTSFIELD -- City officials hope to definitively identify a sewer line leak that has resulted in sewage spills from a stormwater drainpipe into Silver Lake.
Commissioner of Public Utilities Bruce Collingwood said Friday his office was notified of sewage leaking into the lake in the vicinity of Fourth Street and Silver Lake Boulevard on Oct. 10. City crews the following week tentatively traced the problem upstream to a suspected hole in a sewer line.
The damage apparently was caused by a contractor doing utility work and accidentally drilling a hole in both sewer and stormwater drain pipes, he said.
The flows into Silver Lake have been intermittent, Collingwood said, because the leak likely only occurs during periods of peak sewer flow. It is believed the leak from the sewer pipe seeps into the nearby stormwater drain pipe, which eventually empties into the lake, Collingwood said.
He said the site will be excavated on Monday, with city officials present, to determine the cause and extent of the damage and method of repair.
