Closed - Combined Sewer Overflow No. 12

This project is complete. CSO 12 was the final project to eliminate combined stormwater and sewer that discharged to CSO #ZZ outfall to the Mascoma River. The project replaced approximately 4,700 feet of Sewer, and 4,300 feet of Water Main and replaced and added over 4,000 feet of Storm Drainage. Most of the Sanitary Sewer was constructed in the 1940s of Vitrified Clay Pipe that was subjected to inflow and infiltration. CSO 12 also added a sidewalk along Mascoma Street to complete the sidewalk connection from Peabody Street to the other side of the bridge over Interstate 89.
