City of Fitchburg, MA – CSS 4D Sewer Separation Project Information
A sewer and drain construction project will begin construction in October, 2013 and continue through the summer of 2015. The project area is generally bound by the Nashua River to the south, Holman Street to the north, Cedar Street and Atlantic Avenue to the west, and Boutelle Street to the east. A related project includes the replacement of the sanitary sewer along John Fitch Highway from Pearl Street to Intervale Road. 

The goal of the project is to construct a new storm sewer system in order to eliminate three Combined Sewer Overflows (CSOs) in the project area and improve water quality in the Nashua River. The project includes installation of approximately 25,000 feet of storm sewers and sanitary sewers, sewer and manhole rehabilitation, water main replacement, and paving. 

Revoli Construction Company from Franklin, MA will be the general contractor for this project.
