Boothbay Harbor Sewer District Superintendent Chris Higgins said Friday that Sargent Corporation is currently on schedule with the Union Street Pump Station project. The project was originally planned to see through the Oak Street portion of work before moving along to the Union Street portion. Last Thursday, Oct. 12, the Boothbay Register reported that Sargent Corporation was considering swapping the two phases of work which Higgins has confirmed is the case.
