The Massachusetts Water Resources Authority is working on the design of a rehabilitation of its Reading Extension Sewer and Metropolitan Sewer, which are a part of the Northern Collection System serving the communities of Wakefield, Stoneham, Woburn and Reading. The 12,240-linear-foot, 95-year-old Reading Extension Sewer was constructed from 1919 to 1921, and consists vitrified clay pipe, 90% of the which is located in the Town of Stoneham.
Internal television inspections of the Reading Extension Sewer revealed that many segments of the pipeline are cracked, broken, or have partially deformed segments. In addition, there are numerous areas of heavy root intrusion. Many manholes along the Reading Extension Sewer are mostly of brick construction and also require repair.
A 2,280-linear-foot portion of the Metropolitan Sewer, which is included in this project, is also a vitrified clay pipe segment, which was constructed in the late 1800s. Recent inspections of this sewer segment, which runs parallel to a portion of the Reading Extension Sewer, revealed both structural and non-structural deficiencies.
In order to address these issues, MWRA has awarded a contract for the design and construction of cured-in-place-pipe rehabilitation and 62 associated manholes and structures. The contractor performing the construction is Green Mountain Pipeline of South Royalton, Vermont. This work is close to MWRA’s on-going Northern Intermediate High water pipeline project.
