The Army Corps of Engineers issued a news release this week seeking public comment on the proposed construction. The pipes will be laid under Salem Harbor and under the federal navigation channel, extending from the SESD plant on Fort Avenue to Marblehead property on Stamski Way.
The old pipelines will be abandoned in place once the new pipes are installed, the release said.
Dredging and excavation will impact 150,000 square feet of “essential fish habitat.” However, the Army Corps made a preliminary determination that the adverse impact “will not be substantial.”
The 20-inch and 24-inch pipes were installed in 1977, when Marblehead joined the SESD, a regional agency that also treats sewage from Salem, Beverly, Peabody and Danvers. The pipes were expected to last at least another 10 years, Taubert said.
“It kind of caught us all by surprise,” he said.
